Canadian Natural Resources Limited Announces 2013 Second Quarter Results

08/08/2013 10:00am

Marketwired Canada


Canadian Natural Resources Limited (TSX:CNQ) (NYSE:CNQ)

"Canadian Natural achieved in the second quarter of 2013 strong quarterly
production from our balanced and diverse asset base," commented Steve Laut,
President of Canadian Natural. "On a per barrel of oil equivalent basis, our
overall Exploration and Production operating costs decreased from last quarter
resulting in excellent overall netbacks. This, along with strong WTI benchmark
pricing, tighter WCS to WTI differentials and better natural gas pricing helped
the Company generate solid cash flow in the quarter.


At Kirby South, we are in the final stages of commissioning. Steam injection is
expected to commence in late August or early September 2013, approximately three
months ahead of the original schedule. Project costs remain within 

our targeted budget. By the fourth quarter of 2014, thermal in situ production
at Kirby South is targeted to grow to 40,000 bbl/d.


Horizon reliability continues to improve after the completion of our first major
maintenance turnaround of the plant in May 2013. We continue to achieve safe,
steady and reliable operations. In June and July 2013, synthetic crude oil
production was 101,000 bbl/d and 110,000 bbl/d, respectively.


During the second quarter, our North America Exploration and Production crude
oil and NGL assets, excluding thermal in situ oil sands, achieved record
quarterly production of approximately 241,000 bbl/d. These volumes were driven
by record quarterly production at our primary heavy crude oil and Pelican Lake
operations. This quarter marks the tenth consecutive quarter that our heavy
crude oil assets have achieved record production and demonstrates the strong
performance ability of the Pelican Lake pool.


As we move into the third quarter of 2013, we expect production volumes to grow
in the quarter. Higher production volumes from thermal in situ operations,
increased reliability at Horizon Oil Sands Mining operations and continued
strong production performance from all other operating areas of the Company are
anticipated. We will continue to operate efficiently and effectively to ensure
industry competitive operating costs."


Corey Bieber, Canadian Natural's Chief Financial Officer, stated, "We are in an
excellent position to realize strong cash flow metrics over the last half of
2013. Midpoint guidance for crude oil production in Q3/13 reflects an increase
of approximately 19% over Q2/13 volumes. Furthermore, heavy oil differentials
have narrowed as expected. At the same time, benchmark North American crude oil
pricing has increased and condensate premium costs have reduced. We target very
robust netbacks in the last half of 2013, which ultimately results in debt
levels reflective of 2012, making our balance sheet even stronger, despite
substantial capital investments of approximately $2.075 billion in the calendar
year of 2013 on the Horizon Project Phase 2/3 expansion."

(1) Adjusted net earnings from operations is a non-GAAP measure that the Company
utilizes to evaluate its performance. The derivation of this measure is
discussed in the Management's Discussion and Analysis ("MD&A"). 


(2) Cash flow from operations is a non-GAAP measure that the Company considers
key as it demonstrates the Company's ability to fund capital reinvestment and
debt repayment. The derivation of this measure is discussed in the MD&A. 


(3) A barrel of oil equivalent ("BOE") is derived by converting six thousand
cubic feet ("Mcf") of natural gas to one barrel ("bbl") of crude oil (6 Mcf:1
bbl). This conversion may be misleading, particularly if used in isolation,
since the 6 Mcf:1 bbl ratio is based on an energy equivalency conversion method
primarily applicable at the burner tip and does not represent a value
equivalency at the wellhead. In comparing the value ratio using current crude
oil prices relative to natural gas prices, the 6 Mcf:1 bbl conversion ratio may
be misleading as an indication of value.


- Canadian Natural generated cash flow from operations of approximately $1.67
billion in Q2/13 compared to approximately $1.57 billion in Q1/13 and
approximately $1.75 billion in Q2/12. The increase from Q1/13 reflects higher
crude oil and NGLs and natural gas netbacks and higher realized synthetic crude
oil ("SCO") pricing partially offset by lower crude oil and SCO sales volumes in
the North America and Oil Sands Mining and Upgrading segments. The cash flow
variance from Q2/12 reflects higher crude oil and NGLs sales volumes, higher
natural gas netbacks, higher realized SCO pricing and the impact of a weaker
Canadian dollar offset by expected lower SCO sales volumes in the Oil Sands
Mining and Upgrading segment and expected lower natural gas sales volumes. 


- Adjusted net earnings from operations in Q2/13 were $462 million compared to
$401 million in Q1/13 and $606 million in Q2/12. Changes in adjusted net
earnings primarily reflect the changes in cash flow from operations.


- Total production for Q2/13 averaged 623,315 BOE/d, within the Company's
previously announced corporate guidance, which ranged from 617,000 BOE/d to
646,000 BOE/d. As expected, production volumes varied from Q2/12 and Q1/13
levels primarily as a result of expected lower volumes in the Oil Sands Mining
and Upgrading segment due to the Company's first major maintenance turnaround at
Horizon Oil Sands ("Horizon") and in the Thermal In Situ Oil Sands segment due
to production cycle timing. 


- In Q2/13, primary heavy crude oil operations achieved record quarterly
production of approximately 136,000 bbl/d, representing the Company's tenth
consecutive quarter of record primary heavy crude oil production. Primary heavy
crude oil production increased 2% and 11% from Q1/13 and Q2/12, respectively.
The Company expects continued strong performance from its primary heavy crude
oil assets during the second half of 2013, which are targeted to deliver a 13%
production increase over 2012 levels. 

 
- In mid-May 2013, facility constraints at Pelican Lake were alleviated with the
completion of a new battery. Both Pelican Lake and Woodenhouse production
volumes ramped up soon afterward. In Q2/13, Pelican Lake operations achieved
record quarterly production volumes of approximately 42,000 bbl/d, 10% higher
than Q1/13 volumes. In June and July 2013, monthly average production increased
to between 45,000 bbl/d and 46,000 bbl/d, demonstrating the reservoir's
continued strong performance. Further production volume increases are expected
through the second half of 2013, with targeted exit volumes for 2013 of
approximately 50,000 bbl/d.


- Kirby South, the next step in the Company's well defined thermal growth plan,
is now in the final stages of commissioning, with first steam-in expected in
late August or early September 2013, three months ahead of schedule. Production
is targeted to ramp up to 40,000 bbl/d of bitumen by Q4/14.


- During May 2013, the first major maintenance turnaround at Horizon was
completed with no major changes to the scope. The sequential start-up of the
operation was executed as planned. Q3/13 Horizon SCO production is targeted to
increase to between 110,000 bbl/d and 115,000 bbl/d as greater reliability and
consistent production is realized after the turnaround. Safe, steady, and
reliable operations continue to be a priority at Horizon.  Annual SCO production
is unchanged and is targeted to range from 100,000 bbl/d to 108,000 bbl/d in
2013. 


- At Septimus, the Company's liquids rich natural gas Montney play, the plant
expansion was completed and expanded production volumes were achieved in July
2013. At the end of July, total production at Septimus reached approximately 90
MMcf/d of natural gas and approximately 8,600 bbl/d of liquids. During Q2/13,
Canadian Natural drilled 6 net wells at Septimus and targets to drill 7
additional net wells in Q3/13. By early September 2013, production is targeted
to grow to plant expansion capacity of 125 MMcf/d of natural gas sales, yielding
approximately 12,200 bbl/d of liquids, through the plant and deep cut
facilities. 


- Subsequent to Q2/13, Canadian Natural announced the acquisition of Barrick
Energy Inc. The production and undeveloped land base is complementary to
Canadian Natural's existing assets and is concentrated in light oil weighted
assets with strong netbacks and a long reserve life. This acquisition adds
approximately 4,200 bbl/d of light crude oil and NGLs and 4.4 MMcf/d of natural
gas production. 


- Subsequent to Q2/13, TransCanada Corporation announced a successful open
season on its Energy East Pipeline project which is anticipated to add 1.1
MMbbl/d of incremental pipeline capacity to the east coast of Canada. Canadian
Natural is a strong supporter of this project and has made commitments of 80,000
bbl/d of crude oil. This commitment is in addition to previously announced
commitments of crude oil to Keystone XL and Trans Mountain Expansion of 120,000
bbl/d and 75,000 bbl/d respectively.

----------------------------------------------------------------------------
----------------------------------------------------------------------------



(i) Based on current indicative pricing as at July 31, 2013.

- As expected, heavy crude oil differentials narrowed during the second quarter,
resulting in more favorable price realizations for the Company. The WCS heavy
crude oil differential ("WCS differential") as a percent of WTI averaged 20% in
Q2/13 compared to 34% in Q1/13 and 24% in Q2/12. In July, August and September
2013, the WCS differential, based on current indicative pricing, narrowed to
14%, 15% and 20%, respectively. 


- The Company uses condensate as a blending diluent for heavy crude oil pipeline
shipments. During Q2/13, condensate price premiums to WTI narrowed to
US$7.27/bbl in Q2/13 compared to US$12.84/bbl in Q1/13. Lower condensate price
premiums are expected to continue in the second half of 2013 resulting in higher
netbacks for the Company's heavy crude oil sales volumes. 


- As expected, the Dated Brent to WTI differential narrowed to US$8.21/bbl in
Q2/13 compared to US$18.09/bbl in Q1/13 and US$14.71/bbl in Q2/12. Overall
pricing relative to Dated Brent pricing for Canadian Natural's North American
crude oil production continues to improve as a result of this narrowing. 


- SCO pricing improved in Q2/13 to US$99.10/bbl compared to US$95.24/bbl in
Q1/13 and US$89.54/bbl in Q2/12 resulting in more favorable price realizations
for the Company.


- Q3/13 production volumes are expected to be strong and will be driven by
increased production volumes from Primrose, strong SCO production due to
improved Horizon reliability, and continued solid performance from the Company's
remaining operating areas. Combining this strong production performance with
favorable WTI pricing, narrow heavy oil differentials, and strong SCO premiums
should result in a strong third quarter performance for the Company.


- Year to date, Canadian Natural has purchased for cancellation 6,937,500 common
shares at a weighted average price of $30.86 per common share.


- Canadian Natural declared a quarterly cash dividend on common shares of
C$0.125 per share payable on October 1, 2013.


OPERATIONS REVIEW AND CAPITAL ALLOCATION 

In order to facilitate efficient operations, Canadian Natural focuses its
activities in core regions where it can own a substantial land base and
associated infrastructure. Land inventories are maintained to enable continuous
exploitation of play types and geological trends, greatly reducing overall
exploration risk. By owning and operating associated infrastructure, the Company
is able to maximize utilization of its production facilities, thereby increasing
control over production costs. Further, the Company maintains large project
inventories and production diversification among each of the commodities it
produces; light and medium crude oil, primary heavy crude oil, Pelican Lake
heavy crude oil, bitumen and SCO (herein collectively referred to as "crude
oil"), natural gas and NGLs. A large diversified project portfolio enables the
effective allocation of capital to higher return opportunities.

Canadian Natural's primary heavy crude oil continues to provide strong netbacks
and a high return on capital in the Company's portfolio of diverse and balanced
assets. In Q2/13 primary heavy crude oil operations achieved record production
volumes of approximately 136,000 bbl/d, resulting in the tenth consecutive
quarter of record primary heavy crude oil production volumes, contributing to
the targeted 13% primary heavy crude oil production growth in 2013. The Company
is targeting to drill another 255 net primary heavy crude oil wells in Q3/13. 


- Production volumes at Woodenhouse during Q2/13 averaged approximately 13,500
bbl/d, representing an increase of 13% from Q1/13 levels of approximately 12,000
bbl/d. Current production from Woodenhouse is approximately 15,000 bbl/d. 


- During Q2/13, reservoir performance from Canadian Natural's industry leading
Pelican Lake polymer flood remained strong. Ten net horizontal production wells
were drilled during the quarter and 13 net horizontal production wells are
targeted in Q3/13. Construction of the new battery at Pelican Lake was
successfully completed in mid-May 2013. Facility constraints that began in Q4/12
have been alleviated by the expansion and as a result, production volumes at
Pelican Lake and Woodenhouse have increased. Pelican Lake operations achieved
record quarterly crude oil production of approximately 42,000 bbl/d in Q2/13,
representing a 10% increase from Q1/13 and a 12% increase from Q2/12.


- North America light crude oil and NGLs Q2/13 production decreased 2% from
Q1/13 due to downtime as a result of expansion activities at Septimus and
Wembley, spring break-up activities and planned turnarounds. The Company drilled
5 net light crude oil wells in Q2/13 and targets to drill 29 additional net
wells in Q3/13. Canadian Natural's light crude oil drilling program will
continue to utilize and advance horizontal multi-frac well technology to access
new reserves in pools across the Company's land base. 


- Total planned drilling activity for Q3/13 includes 297 net crude oil wells,
excluding stratigraphic ("strat") and service wells.

- Q2/13 thermal in situ oil sands ("thermal in situ") production volumes
averaged approximately 90,000 bbl/d due to the timing of steaming and production
cycles.


- During the second quarter of 2013, bitumen emulsion was discovered at surface
at four separate locations in the Company's Primrose development area. The
bitumen emulsion seepage has been controlled to specific containment areas
totaling 13.5 hectares where it is effectively recovered as it reaches the
surface. The rate of bitumen emulsion seepage in all four locations has declined
as expected and currently totals less than 20 bbl/d. Canadian Natural believes
the cause of the bitumen emulsion seepage is mechanical failures of wellbores in
the vicinity of the impacted locations. A complete review is ongoing and
Canadian Natural has a specialized team focused on investigating wells in the
impacted areas for potential required remediation work.


- The Company's near term steaming plan at Primrose has been modified, with
restrictions on steaming in some areas until the investigation with the Alberta
Energy Regulator is complete.  Canadian Natural's July 2013 production was
approximately 120,000 bbl/d with an additional 20,000 bbl/d of production
capacity that was restricted due to available plant capacity. The Company
targets 2013 thermal in situ production to range from 100,000 bbl/d to 107,000
bbl/d. For 2014, even with these modified steaming strategies, the Company
anticipates thermal in situ production, excluding Kirby South, to range from
100,000 bbl/d to 110,000 bbl/d, approximately 10,000 bbl/d less than originally
targeted. The Company is of the view that reserves recovered from the Primrose
area over its life cycle will be substantially unchanged.


- Kirby South remains ahead of plan and on budget. Drilling was successfully
completed on the seventh and final pad in Q2/13. Commissioning is nearing
completion with first steam-in expected in late August or early September 2013,
ahead of the originally scheduled steam-in date of November 2013. Production is
targeted to grow to 40,000 bbl/d by Q4/14.


- Detailed engineering is progressing for Kirby North Phase 1. As of June 30,
2013, the engineering portion was 64% complete. Construction of the main access
road has been completed and site preparation will continue into Q3/13. 


- Kirby South and Kirby North Phase 1 will contribute to a targeted staged
expansion of production volumes from the greater Kirby area over time to 140,000
bbl/d, with the overall thermal in situ development plan targeted to increase to
510,000 bbl/d of production capacity. 


- Planned drilling activity for Q3/13 includes 47 net thermal in situ wells,
excluding strat and service wells.

- During Q2/13, North America natural gas production averaged 1,092 MMcf/d,
representing a 11% decrease from Q2/12 levels and a 3% decrease from Q1/13
levels. The decrease in production levels year over year was due to expected
production declines, reflecting Canadian Natural's strategic decision to
allocate capital to higher return crude oil projects. Q3/13 production volumes
are targeted to increase to 1,135 MMcf/d to 1,155 MMcf/d. 


- At Septimus, the Company's liquids rich natural gas Montney play, the plant
expansion was completed and first production was achieved in July 2013. At the
end of July, total production at Septimus reached approximately 90 MMcf/d of
natural gas and approximately 8,600 bbl/d of liquids. During Q2/13, Canadian
Natural drilled 6 net wells at Septimus and targets to drill 7 additional net
wells in Q3/13. By early September 2013, production is targeted to grow to plant
expansion capacity of 125 MMcf/d of natural gas sales, yielding 12,200 bbl/d of
liquids, through the plant and deep cut facilities.


- Canadian Natural has a dominant Montney land position with over one million
high quality net acres, the largest in the industry. In Q1/13, the Company
commenced the process to monetize approximately 243,000 net acres (approximately
380 net sections) of its Montney land base in the liquids rich fairway in the
Graham Kobes area of Northeast British Columbia. In Q2/13, the Information
Memorandum was completed. The Company targets to open the associated data room
in mid to late August 2013 and conduct presentations in September 2013.

- International crude oil production averaged 36,956 bbl/d during the quarter.
The 6% increase in production from Q1/13 was primarily due to the stabilization
of the midwater arch which resulted in a reinstatement of production at the
Olowi Field in Gabon in late Q1/13. Crude oil production volumes declined 3%
from Q2/12 as a result of natural field declines and the cessation of North Sea
drilling activity following an increase in the Supplementary Charge Tax Rate in
2011. 


- In Q2/13, the Company received a second Brownfield Allowance ("BFA") approval
for its Ninian Field development plan which includes four new production wells,
four injectors and two well upgrades. The Company received its first BFA
approval in Q1/13 for its Tiffany field development plan of a two well infill
drilling program which achieved first oil in May 2013. In September 2012, the UK
government announced the implementation of the BFA, which allows for a property
development allowance on qualifying preapproved field developments. This
allowance partially mitigates the impact of previous tax increases.

 
- The light crude oil infill drilling program at Espoir, Côte d'Ivoire,
originally targeted to commence in late Q2/13, has been delayed as the Company
is demobilizing the current drilling rig due to ongoing operational and safety
issues with the drilling contractor. Canadian Natural is currently re-assessing
its drilling options at Espoir, where the Company expects to undertake an 8-well
drilling program.


- During Q2/13, Canadian Natural acquired operatorship and a 60% working
interest of Block 12 in Côte d'Ivoire, located approximately 35 km west of the
Company's current production at Espoir and Baobab. The Company plans to commence
new 3D seismic acquisition in Q4/13. Potential exploration drilling is targeted
for 2015 to evaluate deepwater channel/fan structures similar to the Jubilee
crude oil discoveries in Ghana and plays elsewhere in offshore Africa.


- Exploration work on Block 514 in Cote d'Ivoire, in which Canadian Natural has
a 36% working interest, is underway and a seismic program has been completed.
Drilling is targeted to commence in the first half of 2014. The Company believes
this block is also prospective for deepwater channel/fan structures similar to
Jubilee. 


- A partner has been selected to jointly conduct exploratory drilling on
Canadian Natural's prospective offshore South Africa property. The Company will
provide further details on the partnership terms upon receipt of regulatory
approval. Targeted drilling windows are from Q4/13 to Q1/14 and from Q4/14 to
Q1/15 and the necessary long-lead equipment has been ordered.

- During Q2/13, SCO production averaged 67,954 bbl/d at Horizon Oil Sands. 
Production volumes were lower than Q1/13 and Q2/12 levels due to the completion
of the Company's first major maintenance turnaround in May 2013. Horizon SCO
production averaged approximately 101,000 bbl/d in June 2013, approximately
110,000 bbl/d in July 2013 and Q3/13 production guidance is targeted to range
from 110,000 bbl/d to 115,000 bbl/d. 2013 annual guidance remains unchanged at
100,000 bbl/d to 108,000 bbl/d of SCO production.


- Canadian Natural's staged expansion to 250,000 bbl/d of SCO production
capacity continues to progress on track. Capital expenditures to date on Phase
2/3 expansion are at or below cost estimates as the Company executes its cost
focused strategy. Expansion work at Horizon will ultimately add an additional
140,000 bbl/d of SCO production in a staged, disciplined manner. Horizon
provides high quality, long life SCO production without decline for decades. 


- An update to the staged Phase 2/3 expansion on an Engineering, Procurement and
Construction basis at the end of Q2/13 is as follows: 


-- Overall Horizon Phase 2/3 expansion is 24% complete. 

-- Reliability - Tranche 2 is 90% complete. An additional 5,000 bbl/d of
production capacity is targeted to be added in 2014.


-- Directive 74 includes technological investment and research into tailings
management. This project remains on track and is currently 18% complete. 


-- Phase 2A is a coker expansion. The expansion is 62% complete, and is targeted
to add 10,000 bbl/d of production capacity in 2015. 


-- Phase 2B is 15% complete. This phase includes lump sum contracts for major
components such as gas/oil hydrotreatment, froth treatment and a hydrogen plant.
This phase is targeted to add another 45,000 bbl/d of production capacity in
2016. 


-- Phase 3 is on track and engineering is underway. This phase is 15% complete,
and includes the addition of supplementary extraction trains. This phase is
targeted to increase production capacity by 80,000 bbl/d in 2017. 


-- The projects which are currently under construction continue to trend at or
below cost estimates. 


- Total capital budgeted for the Horizon Phase 2/3 expansion in 2013 is $2.075
billion. Canadian Natural continues to be disciplined and cost driven in the
Horizon Phase 2/3 expansion to ensure the expansion continues effectively and
efficiently.

(i) Based on current indicative pricing as at July 31, 2013. 

- As expected, heavy crude oil differentials narrowed during the second quarter,
resulting in more favorable price realizations for the Company. The WCS
differential averaged 20% in Q2/13 compared to 34% in Q1/13 and 24% in Q2/12.
The differential narrowed during Q2/13 compared to Q1/13 due to increased
seasonal demand for heavy crude oil, increased pipeline capacity resulting from
improved pipeline reliability, and lower unplanned maintenance activity at
refineries accessible to Canadian heavy crude oil. In July, August and September
2013, the WCS differential, based on current indicative pricing, narrowed to
14%, 15% and 20%, respectively.


- Canadian Natural contributed over 172,000 bbl/d of its heavy crude oil blends
to the WCS blend in Q2/13. The Company remains the largest contributor to the
WCS blend, accounting for over 62% of the total blend this quarter. 


- The Company uses condensate as a blending diluent for heavy crude oil pipeline
shipments. Condensate price premiums to WTI narrowed to US$7.27/bbl in Q2/13
compared to US$12.84/bbl in Q1/13, reflecting normal seasonality. Lower
condensate price premiums are expected to continue in the second half of 2013
resulting in higher netbacks for the Company's heavy crude oil sales volumes.


- As expected, the Dated Brent to WTI differential narrowed to US$8.21/bbl in
Q2/13 compared to US$18.09/bbl in Q1/13 and US$14.71/bbl in Q2/12, reflecting
continued debottlenecking of the logistical constraints between Cushing and the
Gulf Coast as incremental pipeline capacity continued to grow. Overall pricing
relative to Dated Brent pricing for Canadian Natural's North American crude oil
production continues to improve as a result of this narrowing. 


- SCO pricing averaged US$99.10/bbl during Q2/13, representing a 4% and 11%
increase from Q1/13 and Q2/12 pricing, respectively. Pricing increases from
Q1/13 and Q2/12 reflect planned and unplanned supply disruptions in Northern
Alberta and overall higher diesel demand and result in more favorable price
realizations for the Company. 


NORTH WEST REDWATER UPGRADING AND REFINING 

In Q2/13 work continued on the North West Redwater refinery and completion is
targeted for mid-2016. The North West Redwater refinery asset strengthens the
Company's position by providing a competitive return on investment and by adding
50,000 bbl/d of bitumen conversion capacity in Alberta which will help reduce
volatility in pricing all Western Canadian heavy crude oil. 


FINANCIAL REVIEW 

The Company continues to implement proven strategies and its disciplined
approach to capital allocation. As a result, the financial position of Canadian
Natural remains strong. Canadian Natural's cash flow generation, credit
facilities, diverse asset base and related capital expenditure programs and
commodity hedging policy all support a flexible financial position and provide
the right financial resources for the near-, mid- and long-term. 


- The Company's strategy is to maintain a diverse portfolio balanced across
various commodity types. The Company achieved production of 623,315 BOE/d for
Q2/13 with approximately 96% of production located in G8 countries.


- Subsequent to Q2/13, the Company increased its forecasted 2013 capital
spending as a result of the Cold Lake pipeline expansion, the Barrick Energy
Inc. acquisition and a minor increase in capital allocated to Exploration and
Production. 


- Canadian Natural has a strong balance sheet with debt to book capitalization
of 29% and debt to EBITDA of 1.4x at June 30, 2013.


- During Q2/13, Canadian Natural's $3,000 million revolving syndicated credit
facility was extended to June 2017. Additionally, the Company issued $500
million of 2.89% medium-term notes due August 2020.  Proceeds from the
securities issued were used to repay bank indebtedness and for general corporate
purposes.


- In Q2/13, the Company completed a full quarter of its US commercial paper
program. Borrowings of up to a maximum of US$1,500 million are authorized. The
program further diversifies the Company's borrowing base and has been well
received.


- Canadian Natural maintains significant financial stability and liquidity
represented by approximately $2.4 billion of available credit under its bank
credit facilities, net of commercial paper issued.


- The Company's commodity hedging program protects investment returns, ensures
ongoing balance sheet strength and supports the Company's cash flow for its
capital expenditure programs. Approximately 58% of forecasted 2013 crude oil
volumes are currently hedged using price collars and physical crude oil sales
contracts with fixed WCS differentials. Through the use of collars, the Company
has hedged approximately 300,000 bbl/d of crude oil volumes in the second half
of 2013, and approximately 150,000 bbl/d of crude oil volumes in 2014. To
partially mitigate its exposure to widening heavy crude oil differentials, the
Company has entered into physical crude oil sales contracts with weighted
average fixed WCS differentials as follows:

----------------------------------------------------------------------------



Details of the Company's commodity hedging program can be found on the Company's
website at www.cnrl.com. 


- Year to date, Canadian Natural has purchased for cancellation 6,937,500 common
shares at a weighted average price of $30.86 per common share.


- Canadian Natural declared a quarterly cash dividend on common shares of
C$0.125 per share payable on October 1, 2013. 


OUTLOOK 

The Company forecasts 2013 production levels before royalties to average between
482,000 and 513,000 bbl/d of crude oil and NGLs and between 1,085 and 1,145
MMcf/d of natural gas. Q3/13 production guidance before royalties is forecast to
average between 506,000 and 529,000 bbl/d of crude oil and NGLs and between
1,135 and 1,155 MMcf/d of natural gas. Detailed guidance on production levels,
capital allocation and operating costs can be found on the Company's website at

MANAGEMENT'S DISCUSSION AND ANALYSIS 

Forward-Looking Statements 

Certain statements relating to Canadian Natural Resources Limited (the
"Company") in this document or documents incorporated herein by reference
constitute forward-looking statements or information (collectively referred to
herein as "forward-looking statements") within the meaning of applicable
securities legislation. Forward-looking statements can be identified by the
words "believe", "anticipate", "expect", "plan", "estimate", "target",
"continue", "could", "intend", "may", "potential", "predict", "should", "will",
"objective", "project", "forecast", "goal", "guidance", "outlook", "effort",
"seeks", "schedule", "proposed" or expressions of a similar nature suggesting
future outcome or statements regarding an outlook. Disclosure related to
expected future commodity pricing, forecast or anticipated production volumes,
royalties, operating costs, capital expenditures, income tax expenses and other
guidance provided throughout this Management's Discussion and Analysis ("MD&A"),
constitute forward-looking statements. Disclosure of plans relating to and
expected results of existing and future developments, including but not limited
to the Horizon Oil Sands operations and future expansions, Primrose thermal
projects, Pelican Lake water and polymer flood project, the Kirby Thermal Oil
Sands Project, construction of the proposed Keystone XL Pipeline from Hardisty,
Alberta to the US Gulf Coast, construction of the proposed Energy East pipeline
to transport crude oil from Alberta to Quebec and New Brunswick, the proposed
Kinder Morgan Trans Mountain pipeline expansion from Edmonton, Alberta to
Vancouver, British Columbia, and the construction and future operations of the
North West Redwater bitumen upgrader and refinery also constitute
forward-looking statements. This forward-looking information is based on annual
budgets and multi-year forecasts, and is reviewed and revised throughout the
year as necessary in the context of targeted financial ratios, project returns,
product pricing expectations and balance in project risk and time horizons.
These statements are not guarantees of future performance and are subject to
certain risks. The reader should not place undue reliance on these
forward-looking statements as there can be no assurances that the plans,
initiatives or expectations upon which they are based will occur. 


In addition, statements relating to "reserves" are deemed to be forward-looking
statements as they involve the implied assessment based on certain estimates and
assumptions that the reserves described can be profitably produced in the
future. There are numerous uncertainties inherent in estimating quantities of
proved and proved plus probable crude oil, natural gas and natural gas liquids
("NGLs") reserves and in projecting future rates of production and the timing of
development expenditures. The total amount or timing of actual future production
may vary significantly from reserve and production estimates. 


The forward-looking statements are based on current expectations, estimates and
projections about the Company and the industry in which the Company operates,
which speak only as of the date such statements were made or as of the date of
the report or document in which they are contained, and are subject to known and
unknown risks and uncertainties that could cause the actual results, performance
or achievements of the Company to be materially different from any future
results, performance or achievements expressed or implied by such
forward-looking statements. Such risks and uncertainties include, among others:
general economic and business conditions which will, among other things, impact
demand for and market prices of the Company's products; volatility of and
assumptions regarding crude oil and natural gas prices; fluctuations in currency
and interest rates; assumptions on which the Company's current guidance is
based; economic conditions in the countries and regions in which the Company
conducts business; political uncertainty, including actions of or against
terrorists, insurgent groups or other conflict including conflict between
states; industry capacity; ability of the Company to implement its business
strategy, including exploration and development activities; impact of
competition; the Company's defense of lawsuits; availability and cost of
seismic, drilling and other equipment; ability of the Company and its
subsidiaries to complete capital programs; the Company's and its subsidiaries'
ability to secure adequate transportation for its products; unexpected
disruptions or delays in the resumption of the mining, extracting or upgrading
of the Company's bitumen products; potential delays or changes in plans with
respect to exploration or development projects or capital expenditures; ability
of the Company to attract the necessary labour required to build its thermal and
oil sands mining projects; operating hazards and other difficulties inherent in
the exploration for and production and sale of crude oil and natural gas and in
mining, extracting or upgrading the Company's bitumen products; availability and
cost of financing; the Company's and its subsidiaries' success of exploration
and development activities and their ability to replace and expand crude oil and
natural gas reserves; timing and success of integrating the business and
operations of acquired companies; production levels; imprecision of reserve
estimates and estimates of recoverable quantities of crude oil, natural gas and
NGLs not currently classified as proved; actions by governmental authorities;
government regulations and the expenditures required to comply with them
(especially safety and environmental laws and regulations and the impact of
climate change initiatives on capital and operating costs); asset retirement
obligations; the adequacy of the Company's provision for taxes; and other
circumstances affecting revenues and expenses. 


The Company's operations have been, and in the future may be, affected by
political developments and by federal, provincial and local laws and regulations
such as restrictions on production, changes in taxes, royalties and other
amounts payable to governments or governmental agencies, price or gathering rate
controls and environmental protection regulations. Should one or more of these
risks or uncertainties materialize, or should any of the Company's assumptions
prove incorrect, actual results may vary in material respects from those
projected in the forward-looking statements. The impact of any one factor on a
particular forward-looking statement is not determinable with certainty as such
factors are dependent upon other factors, and the Company's course of action
would depend upon its assessment of the future considering all information then
available. 


Readers are cautioned that the foregoing list of factors is not exhaustive.
Unpredictable or unknown factors not discussed in this report could also have
material adverse effects on forward-looking statements. Although the Company
believes that the expectations conveyed by the forward-looking statements are
reasonable based on information available to it on the date such forward-looking
statements are made, no assurances can be given as to future results, levels of
activity and achievements. All subsequent forward-looking statements, whether
written or oral, attributable to the Company or persons acting on its behalf are
expressly qualified in their entirety by these cautionary statements. Except as
required by law, the Company assumes no obligation to update forward-looking
statements, whether as a result of new information, future events or other
factors, or the foregoing factors affecting this information, should
circumstances or Management's estimates or opinions change. 


Management's Discussion and Analysis 

This MD&A of the financial condition and results of operations of the Company
should be read in conjunction with the unaudited interim consolidated financial
statements for the three and six months ended June 30, 2013 and the MD&A and the
audited consolidated financial statements for the year ended December 31, 2012. 


All dollar amounts are referenced in millions of Canadian dollars, except where
noted otherwise. The Company's consolidated financial statements for the period
ended June 30, 2013 and this MD&A have been prepared in accordance with
International Financial Reporting Standards ("IFRS") as issued by the
International Accounting Standards Board. This MD&A includes references to
financial measures commonly used in the crude oil and natural gas industry, such
as adjusted net earnings from operations, cash flow from operations, and cash
production costs. These financial measures are not defined by IFRS and therefore
are referred to as non-GAAP measures. The non-GAAP measures used by the Company
may not be comparable to similar measures presented by other companies. The
Company uses these non-GAAP measures to evaluate its performance. The non-GAAP
measures should not be considered an alternative to or more meaningful than net
earnings, as determined in accordance with IFRS, as an indication of the
Company's performance. The non-GAAP measures adjusted net earnings from
operations and cash flow from operations are reconciled to net earnings, as
determined in accordance with IFRS, in the "Financial Highlights" section of
this MD&A. The derivation of cash production costs is included in the "Operating
Highlights - Oil Sands Mining and Upgrading" section of this MD&A. The Company
also presents certain non-GAAP financial ratios and their derivation in the
"Liquidity and Capital Resources" section of this MD&A. 


A Barrel of Oil Equivalent ("BOE") is derived by converting six thousand cubic
feet ("Mcf") of natural gas to one barrel ("bbl") of crude oil (6 Mcf:1 bbl).
This conversion may be misleading, particularly if used in isolation, since the
6 Mcf:1 bbl ratio is based on an energy equivalency conversion method primarily
applicable at the burner tip and does not represent a value equivalency at the
wellhead. In comparing the value ratio using current crude oil prices relative
to natural gas prices, the 6 Mcf:1 bbl conversion ratio may be misleading as an
indication of value. In addition, for the purposes of this MD&A, crude oil is
defined to include the following commodities: light and medium crude oil,
primary heavy crude oil, Pelican Lake heavy crude oil, bitumen (thermal oil),
and synthetic crude oil. 


Production volumes and per unit statistics are presented throughout this MD&A on
a "before royalty" or "gross" basis, and realized prices are net of blending
costs and exclude the effect of risk management activities. Production on an
"after royalty" or "net" basis is also presented for information purposes only. 


The following discussion refers primarily to the Company's financial results for
the three and six months ended June 30, 2013 in relation to the comparable
periods in 2012 and the first quarter of 2013. The accompanying tables form an
integral part of this MD&A. Additional information relating to the Company,
including its Annual Information Form for the year ended December 31, 2012, is
available on SEDAR at www.sedar.com, and on EDGAR at www.sec.gov. This MD&A is
dated August 7, 2013.

(1) Adjusted net earnings from operations is a non-GAAP measure that represents
net earnings adjusted for certain items of a non-operational nature. The Company
evaluates its performance based on adjusted net earnings from operations. The
reconciliation "Adjusted Net Earnings from Operations" presents the after-tax
effects of certain items of a non-operational nature that are included in the
Company's financial results. Adjusted net earnings from operations may not be
comparable to similar measures presented by other companies. 


(2) Cash flow from operations is a non-GAAP measure that represents net earnings
adjusted for non-cash items before working capital adjustments. The Company
evaluates its performance based on cash flow from operations. The Company
considers cash flow from operations a key measure as it demonstrates the
Company's ability to generate the cash flow necessary to fund future growth
through capital investment and to repay debt. The reconciliation "Cash Flow from
Operations" presents certain non-cash items that are included in the Company's
financial results. Cash flow from operations may not be comparable to similar
measures presented by other companies.

(1) The Company's employee stock option plan provides for a cash payment option.
Accordingly, the fair value of the outstanding vested options is recorded as a
liability on the Company's balance sheets and periodic changes in the fair value
are recognized in net earnings or are capitalized to Oil Sands Mining and
Upgrading construction costs. 


(2) Derivative financial instruments are recorded at fair value on the balance
sheets, with changes in the fair value of non-designated hedges recognized in
net earnings. The amounts ultimately realized may be materially different than
reflected in the financial statements due to changes in prices of the underlying
items hedged, primarily crude oil and natural gas. 


(3) Unrealized foreign exchange gains and losses result primarily from the
translation of US dollar denominated long-term debt to period-end exchange
rates, partially offset by the impact of cross currency swaps, and are
recognized in net earnings. 


(4) During the first quarter of 2013, the Company repaid US$400 million of 5.15%
unsecured notes. 


(5) All substantively enacted adjustments in applicable income tax rates and
other legislative changes are applied to underlying assets and liabilities on
the Company's balance sheets in determining deferred income tax assets and
liabilities. The impact of these tax rate and other legislative changes is
recorded in net earnings during the period the legislation is substantively
enacted. During the second quarter of 2013, the government of British Columbia
substantively enacted legislation to increase its provincial corporate income
tax rate effective April 1, 2013, resulting in an increase in the Company's
deferred income tax liability of $15 million.

SUMMARY OF CONSOLIDATED NET EARNINGS AND CASH FLOW FROM OPERATIONS 

Net earnings for the six months ended June 30, 2013 were $689 million compared
with $1,180 million for the six months ended June 30, 2012. Net earnings for the
six months ended June 30, 2013 included net after-tax expenses of $174 million
compared with net after-tax income of $274 million for the six months ended June
30, 2012 related to the effects of share-based compensation, risk management
activities, fluctuations in foreign exchange rates including the impact of a
realized foreign exchange gain on repayment of long-term debt, and the impact of
statutory tax rate and other legislative changes on deferred income tax
liabilities. Excluding these items, adjusted net earnings from operations for
the six months ended June 30, 2013 were $863 million compared with $906 million
for the six months ended June 30, 2012. 


Net earnings for the second quarter of 2013 were $476 million compared with $753
million for the second quarter of 2012 and $213 million for the first quarter of
2013. Net earnings for the second quarter of 2013 included net after-tax income
of $14 million compared with $147 million for the second quarter of 2012 and net
after-tax expenses of $188 million for the first quarter of 2013 related to the
effects of share-based compensation, risk management activities, fluctuations in
foreign exchange rates including the impact of a realized foreign exchange gain
on repayment of long-term debt, and the impact of statutory tax rate and other
legislative changes on deferred income tax liabilities. Excluding these items,
adjusted net earnings from operations for the second quarter of 2013 were $462
million compared with $606 million for the second quarter of 2012 and $401
million for the first quarter of 2013. 


The decrease in adjusted net earnings for the six months ended June 30, 2013
from the comparable period in 2012 was primarily due to:


- lower crude oil and NGLs netbacks; 

- lower natural gas sales volumes; and 

- higher depletion, depreciation and amortization expense; 

partially offset by:

- higher crude oil and synthetic crude oil ("SCO") sales volumes in the North
America and Oil Sands Mining and Upgrading segments; 


- higher realized natural gas netbacks; 

- higher realized SCO prices; 

- higher realized risk management gains; and 

- the impact of a weaker Canadian dollar. 

The decrease in adjusted net earnings for the second quarter of 2013 from the
comparable period in 2012 was primarily due to:


- lower SCO sales volumes in the Oil Sands Mining and Upgrading segment due to
the May 2013 turnaround; 


- lower natural gas sales volumes; 

- lower realized risk management gains; and 

- higher depletion, depreciation and amortization expense; 

partially offset by:

- higher crude oil and NGLs sales volumes; 

- higher natural gas netbacks; 

- higher realized SCO prices; and 

- the impact of a weaker Canadian dollar. 

The increase in adjusted net earnings for the second quarter of 2013 from the
first quarter of 2013 was primarily due to:


- higher crude oil and NGLs and natural gas netbacks; 

- higher realized SCO prices; and 

- the impact of a weaker Canadian dollar; 

partially offset by:

- lower crude oil and SCO sales volumes in the North America and Oil Sands
Mining and Upgrading segments; and 


- lower realized risk management gains. 

The impacts of share-based compensation, risk management activities and changes
in foreign exchange rates are expected to continue to contribute to quarterly
volatility in consolidated net earnings and are discussed in detail in the
relevant sections of this MD&A. 


Cash flow from operations for the six months ended June 30, 2013 was $3,241
million compared with $3,034 million for the six months ended June 30, 2012.
Cash flow from operations for the second quarter of 2013 was $1,670 million
compared with $1,754 million for the second quarter of 2012 and $1,571 million
for the first quarter of 2013. The fluctuations in cash flow from operations
from the comparable periods were primarily due to the factors noted above
relating to the fluctuations in adjusted net earnings, excluding depletion,
depreciation and amortization expense, as well as due to the impact of cash
taxes. 


Total production before royalties for the six months ended June 30, 2013
increased 1% to 651,921 BOE/d from 645,943 BOE/d for the six months ended June
30, 2012. Total production before royalties for the second quarter of 2013
decreased 8% to 623,315 BOE/d from 679,607 BOE/d for the second quarter of 2012
and 680,844 BOE/d for the first quarter of 2013.

----------------------------------------------------------------------------
----------------------------------------------------------------------------



Volatility in the quarterly net earnings over the eight most recently completed
quarters was primarily due to:


- Crude oil pricing - The impact of fluctuating demand, inventory storage levels
and geopolitical uncertainties on worldwide benchmark pricing, the impact of the
WCS Heavy Differential from West Texas Intermediate reference location at
Cushing, Oklahoma ("WTI") in North America and the impact of the differential
between WTI and Dated Brent benchmark pricing in the North Sea and Offshore
Africa. 


- Natural gas pricing - The impact of fluctuations in both the demand for
natural gas and inventory storage levels, and the impact of increased shale gas
production in the US. 


- Crude oil and NGLs sales volumes - Fluctuations in production due to the
cyclic nature of the Company's Primrose thermal projects, the results from the
Pelican Lake water and polymer flood projects, the record heavy crude oil
drilling program, and the impact of the turnaround/suspension and subsequent
recommencement of production at Horizon. Sales volumes also reflected
fluctuations due to timing of liftings and maintenance activities in the North
Sea and Offshore Africa. 


- Natural gas sales volumes - Fluctuations in production due to the Company's
strategic decision to reduce natural gas drilling activity in North America and
the allocation of capital to higher return crude oil projects, as well as
natural decline rates, shut-in natural gas production due to pricing and the
impact and timing of acquisitions. 


- Production expense - Fluctuations primarily due to the impact of the demand
for services, fluctuations in product mix, the impact of seasonal costs that are
dependent on weather, production and cost optimizations in North America,
acquisitions of natural gas producing properties in 2011 that had higher
operating costs per Mcf than the Company's existing properties, and the
turnaround/suspension and subsequent recommencement of production at Horizon. 


- Depletion, depreciation and amortization - Fluctuations due to changes in
sales volumes, proved reserves, asset retirement obligations, finding and
development costs associated with crude oil and natural gas exploration,
estimated future costs to develop the Company's proved undeveloped reserves, and
the impact of the turnaround/suspension and subsequent recommencement of
production at Horizon. 


- Share-based compensation - Fluctuations due to the determination of fair
market value based on the Black-Scholes valuation model of the Company's
share-based compensation liability. 


- Risk management - Fluctuations due to the recognition of gains and losses from
the mark-to-market and subsequent settlement of the Company's risk management
activities. 


- Foreign exchange rates - Changes in the Canadian dollar relative to the US
dollar that impacted the realized price the Company received for its crude oil
and natural gas sales, as sales prices are based predominately on US dollar
denominated benchmarks. Fluctuations in realized and unrealized foreign exchange
gains and losses are also recorded with respect to US dollar denominated debt,
partially offset by the impact of cross currency swap hedges. 


- Income tax expense - Fluctuations in income tax expense include statutory tax
rate and other legislative changes substantively enacted in the various periods.

Commodity Prices 

Crude oil sales contracts in the North America segment are typically based on
WTI benchmark pricing. WTI averaged US$94.28 per bbl for the six months ended
June 30, 2013, a decrease of 4% from US$98.22 per bbl for the six months ended
June 30, 2012. WTI averaged US$94.23 per bbl for the second quarter of 2013 and
was consistent with the comparative periods. 


Crude oil sales contracts for the Company's North Sea and Offshore Africa
segments are typically based on Dated Brent ("Brent") pricing, which is
representative of international markets and overall world supply and demand.
Brent averaged US$107.41 per bbl for the six months ended June 30, 2013, a
decrease of 5% from US$113.34 per bbl for the six months ended June 30, 2012.
Brent averaged US$102.44 per bbl for the second quarter of 2013, a decrease of
5% from US$108.21 per bbl for the second quarter of 2012, and a decrease of 9%
from US$112.43 per bbl for the first quarter of 2013. 


The Brent differential from WTI tightened for the three and six months ended
June 30, 2013 from the comparable periods due to incremental pipeline capacity
reflecting a continued debottlenecking of logistical constraints from Cushing to
the US Gulf Coast. 


The WCS Heavy Differential averaged 27% for the six months ended June 30, 2013
compared with 23% for the six months ended June 30, 2012. The WCS Heavy
Differential averaged 20% for the second quarter of 2013 compared with 24% for
the second quarter of 2012, and 34% for the first quarter of 2013. The WCS Heavy
Differential tightened in the second quarter of 2013 from the comparable periods
as a result of increased seasonal heavy oil demand and increased pipeline
capacity as pipeline reliability in the second quarter of 2013 improved. The WCS
Heavy Differential per barrel tightened in July 2013 to average US$14.20 per bbl
and in August 2013 to average US$15.57 per bbl. To partially mitigate its
exposure to widening heavy crude oil differentials, as at June 30, 2013, the
Company has entered into physical crude oil sales contracts with weighted
average fixed WCS differentials as follows: 20,000 bbl/d in the third quarter of
2013 at US$21.27 per bbl; 15,000 bbl/d in the fourth quarter of 2013 at US$21.52
per bbl; 8,000 bbl/d in the first quarter of 2014 at US$21.89 per bbl; 9,000
bbl/d in the second quarter of 2014 at US$21.93 per bbl; and 10,000 bbl/d in the
third and fourth quarters of 2014 at US$20.81. 


The SCO price averaged US$97.18 per bbl for the six months ended June 30, 2013,
an increase of 4% from US$93.82 per bbl for the six months ended June 30, 2012.
The SCO price averaged US$99.10 per bbl for the second quarter of 2013, an
increase of 11% from US$89.54 per bbl for the second quarter of 2012, and an
increase of 4% from US$95.24 per bbl for the first quarter of 2013. The increase
in SCO pricing for the three and six months ended June 30, 2013 from the
comparable periods was due to planned and unplanned shutdowns of various
upgrading facilities in Northern Alberta. 


The Company uses condensate as a blending diluent for heavy crude oil pipeline
shipments. During the second quarter of 2013, condensate price premiums to WTI
narrowed, reflecting normal seasonality. 


The Company anticipates continued volatility in crude oil pricing benchmarks due
to supply and demand factors, geopolitical events, and the timing and extent of
the economic recovery. The WCS Heavy Differential is expected to continue to
reflect seasonal demand fluctuations, changes in transportation logistics, and
refinery utilization and shutdowns.


NYMEX natural gas prices averaged US$3.72 per MMBtu for the six months ended
June 30, 2013, an increase of 48% from US$2.52 per MMBtu for the six months
ended June 30, 2012. NYMEX natural gas prices averaged US$4.09 per MMBtu for the
second quarter of 2013, an increase of 81% from US$2.26 per MMBtu for the second
quarter of 2012, and an increase of 22% from US$3.35 per MMBtu for the first
quarter of 2013. 


AECO natural gas prices for the six months ended June 30, 2013 averaged $3.16
per GJ, an increase of 53% from $2.06 per GJ for the six months ended June 30,
2012. AECO natural gas prices for the second quarter of 2013 averaged $3.41 per
GJ, an increase of 96% from $1.74 per GJ for the second quarter of 2012, and an
increase of 17% from $2.92 per GJ for the first quarter of 2013. 


During the second quarter of 2013, natural gas prices continued to recover from
the low pricing levels in 2012. A steady North America production supply
forecast and a return to normal winter weather in North America in 2013 has
allowed natural gas inventories to return to seasonal levels. 


The Company continues to focus on its crude oil marketing strategy including a
blending strategy that expands markets within current pipeline infrastructure,
supporting pipeline projects that provide crude oil transportation to new
markets, and supporting incremental heavy crude oil conversion capacity.
Subsequent to June 30, 2013, the Company entered into a 20 year transportation
agreement to ship 80,000 bbl/d of crude oil on the proposed Energy East
pipeline, subject to regulatory approval.

The Company's business approach is to maintain large project inventories and
production diversification among each of the commodities it produces; namely
natural gas, light and medium crude oil and NGLs, primary heavy crude oil,
Pelican Lake heavy crude oil, bitumen (thermal oil) and SCO. 


Crude oil and NGLs production for the six months ended June 30, 2013 increased
7% to 462,615 bbl/d from 432,993 bbl/d for the six months ended June 30, 2012.
Crude oil and NGLs production for the second quarter of 2013 decreased 7% to
436,363 bbl/d from 470,523 bbl/d for the second quarter of 2012 and decreased
11% from 489,157 bbl/d for the first quarter of 2013. The increase in production
for the six months ended June 30, 2013 from the comparable period in 2012 was
primarily due to the impact of a strong heavy crude oil drilling program, and
the increased production from the Company's cyclic thermal operations and
Horizon. The decrease in production for the second quarter of 2013 from the
comparable periods was primarily due to the decrease in production volumes
resulting from Horizon's planned maintenance turnaround in May 2013 and from
fluctuations in the Company's cyclic thermal operations, partially offset by the
impact of a strong heavy crude oil drilling program. Crude oil and NGLs
production in the second quarter of 2013 was within the Company's previously
issued guidance of 435,000 to 461,000 bbl/d. 


Natural gas production for the six months ended June 30, 2013 decreased 11% to
1,136 MMcf/d from 1,277 MMcf/d for the six months ended June 30, 2012. Natural
gas production for the second quarter of 2013 decreased 11% to 1,122 MMcf/d from
1,255 MMcf/d for the second quarter of 2012 and decreased 2% from 1,150 MMcf/d
for the first quarter of 2013. The decrease in natural gas production for the
three and six months ended June 30, 2013 from the comparable periods was
primarily a result of a strategic reduction of natural gas drilling as the
Company allocated capital to higher return crude oil projects, as well as
expected production declines. Natural gas production in the second quarter of
2013 exceeded the Company's previously issued guidance of 1,090 to 1,110 MMcf/d.



For 2013, annual production guidance is targeted to average between 482,000 and
513,000 bbl/d of crude oil and NGLs and between 1,085 and 1,145 MMcf/d of
natural gas. Third quarter 2013 production guidance is targeted to average
between 506,000 and 529,000 bbl/d of crude oil and NGLs and between 1,135 and
1,155 MMcf/d of natural gas. 


North America - Exploration and Production 

North America crude oil and NGLs production for the six months ended June 30,
2013 increased 9% to average 338,433 bbl/d from 311,048 bbl/d for the six months
ended June 30, 2012. For the second quarter of 2013, crude oil and NGLs
production increased 5% to average 331,453 bbl/d compared with 316,483 bbl/d for
the second quarter of 2012 and decreased 4% from 345,489 bbl/d for the first
quarter of 2013. The increase in crude oil and NGLs production for the three and
six months ended June 30, 2013 from the comparable periods in 2012 was primarily
due to the impact of a strong heavy crude oil drilling program. The decrease for
the second quarter of 2013 from the first quarter of 2013 was primarily due to
the decrease in production from the Company's cyclic thermal operations. Second
quarter 2013 production of crude oil and NGLs was within the Company's
previously issued guidance of 326,000 to 342,000 bbl/d. Third quarter 2013
production guidance is targeted to average between 365,000 and 380,000 bbl/d for
crude oil and NGLs. 


Natural gas production for the six months ended June 30, 2013 decreased 12% to
1,108 MMcf/d compared with 1,255 MMcf/d for the six months ended June 30, 2012.
Natural gas production decreased 11% to 1,092 MMcf/d for the second quarter of
2013 compared with 1,230 MMcf/d in the second quarter of 2012 and decreased 3%
from 1,125 MMcf/d for the first quarter of 2013. The decrease in natural gas
production for the three and six months ended June 30, 2013 from the comparable
periods was primarily a result of a strategic reduction of natural gas drilling
as the Company allocated capital to higher return crude oil projects, as well as
expected production declines. 


North America - Oil Sands Mining and Upgrading 

Production averaged 88,255 bbl/d for the six months ended June 30, 2013 compared
with 80,957 bbl/d for the six months ended June 30, 2012. For the second quarter
of 2013, SCO production averaged 67,954 bbl/d compared with 115,823 bbl/d for
the second quarter of 2012 and 108,782 bbl/d for the first quarter of 2013.
Production increased for the six months ended June 30, 2013 from the comparable
period due to the unplanned maintenance completed during the first quarter of
2012. Second quarter 2013 production reflected the impact of the planned
maintenance turnaround. Due to a 6 day extension of the planned turnaround to 30
days from the 24 days originally forecasted, SCO production was below the
Company's previously issued guidance of 77,000 to 83,000 bbl/d for the second
quarter of 2013. Third quarter 2013 production guidance is targeted to average
between 110,000 and 115,000 bbl/d. Annual 2013 production guidance remains
unchanged and is targeted to average between 100,000 and 108,000 bbl/d. 


North Sea 

North Sea crude oil production for the six months ended June 30, 2013 decreased
7% to 18,838 bbl/d from 20,333 bbl/d for the six months ended June 30, 2012.
Second quarter 2013 North Sea crude oil production increased 7% to 18,901 bbl/d
compared with 17,619 bbl/d for the second quarter of 2012, and was comparable
with the first quarter of 2013. The decrease in production for the six months
ended June 30, 2013 from the comparable period was primarily due to natural
field declines and a reduction in drilling activities as a result of an increase
in the UK corporate income tax rate in 2011. The increase in production for the
second quarter of 2013 from the second quarter of 2012 was primarily due to
higher production from both the Tiffany and Ninian fields in 2013, as well as
the temporary shut in of the third-party operated pipeline to Sullom Voe for
unplanned maintenance for a portion of 2012, which caused all Ninian and
associated fields to be shut in. 


The Company received approval for the Brownfield Allowance for the Tiffany field
in January 2013 and as a result, during the second quarter the Company drilled
one injector well and one additional production well, which came on at Tiffany
with production of approximately 1,500 bbl/d, exceeding original forecasted
volumes. During the second quarter of 2013, the Company also completed its
consolidation of a working interest in a satellite field at the Ninian hub. 


In December 2011, the Banff Floating Production, Storage and Offloading Vessel
("FPSO") and subsea infrastructure suffered storm damage. Operations at
Banff/Kyle, with combined net production of approximately 3,500 bbl/d, were
suspended. The FPSO and associated floating storage unit were subsequently
removed from the field and the FPSO is currently undergoing repairs and is
targeted to be back in the field in the first half of 2014. The associated
repair costs, net of insurance recoveries, are not expected to be significant. 


Offshore Africa 

Offshore Africa crude oil production decreased 17% to 17,089 bbl/d for the six
months ended June 30, 2013 from 20,655 bbl/d for the six months ended June 30,
2012. Second quarter 2013 crude oil production averaged 18,055 bbl/d, decreasing
12% from 20,598 bbl/d for the second quarter of 2012 and increasing 12% from
16,112 bbl/d for the first quarter of 2013. The decrease in production volumes
for the three and six months ended June 30, 2013 from the comparable periods in
2012 was due to natural field declines and lower production from Gabon. The
increase in production volumes for the second quarter of 2013 from the first
quarter of 2013 was due to the stabilization of the midwater arch and the
reinstatement of production at the Olowi field in Gabon late in the first
quarter of 2013. The final repairs and assessment have been made and issues
relating to the long-term operability of the midwater arch have been resolved. 


International Guidance 

The Company's North Sea and Offshore Africa second quarter 2013 crude oil and
NGLs production exceeded the Company's previously issued guidance of 32,000 to
36,000 bbl/d. Third quarter 2013 production guidance is targeted to average
between 31,000 and 34,000 bbl/d of crude oil and NGLs. 


Crude Oil Inventory Volumes 

The Company recognizes revenue on its crude oil production when title transfers
to the customer and delivery has taken place. Revenue has not been recognized on
crude oil volumes that were stored in various tanks, pipelines, or FPSOs, as
follows:

North America 

North America realized crude oil prices decreased 12% to average $63.66 per bbl
for the six months ended June 30, 2013 from $71.99 per bbl for the six months
ended June 30, 2012. North America realized crude oil prices averaged $71.81 per
bbl for the second quarter of 2013, an increase of 6% compared with $67.44 per
bbl for the second quarter of 2012 and an increase of 29% compared with $55.68
per bbl for the first quarter of 2013. The decrease in realized crude oil prices
for the six months ended June 30, 2013 from the comparable period was due to the
widening of the WCS Heavy Differential, lower WTI benchmark pricing, and higher
diluent blending costs, partially offset by the impact of a weaker Canadian
dollar relative to the US dollar. The increase in realized crude oil prices for
the second quarter of 2013 from the comparable periods was due to the impact of
the tightening of the WCS Heavy Differential and the weaker Canadian dollar
relative to the US dollar. The Company continues to focus on its crude oil
blending marketing strategy and in the second quarter of 2013 contributed
approximately 172,000 bbl/d of heavy crude oil blends to the WCS stream. 


North America realized natural gas prices increased 56% to average $3.63 per Mcf
for the six months ended June 30, 2013 from $2.32 per Mcf for the six months
ended June 30, 2012. North America realized natural gas prices increased 96% to
average $3.90 per Mcf for the second quarter of 2013 compared with $1.99 per Mcf
in the second quarter of 2012, and increased 16% compared with $3.37 per Mcf for
the first quarter of 2013. The increase in realized natural gas prices for the
three and six months ended June 30, 2013 from the comparable periods was
primarily due to higher AECO benchmark pricing related to the impact of a steady
North America production supply forecast and a return to normal winter weather
in North America in 2013, that has allowed natural gas inventories to return to
seasonal levels.


Comparisons of the prices received in North America Exploration and Production
by product type were as follows:

North America 

North America crude oil and natural gas royalties for the six months ended June
30, 2013 compared with the six months ended June 30, 2012 reflected movements in
benchmark commodity prices and the fluctuations of the WCS Heavy Differential. 


Crude oil and NGLs royalties averaged approximately 17% of product sales for the
second quarter of 2013 compared with 13% for the second quarter of 2012 and 16%
for the first quarter of 2013. The increase in royalties from the second quarter
of 2012 was primarily due to the increase in realized crude oil and NGLs prices.
Crude oil and NGLs royalties per bbl are anticipated to average 16% to 18% of
product sales for 2013. 


Natural gas royalties averaged approximately 7% of product sales for the second
quarter of 2013 compared with 1% for the second quarter of 2012 and 3% for the
first quarter of 2013. The increase in natural gas royalty rates from the second
quarter of 2012 was primarily the result of the increase in realized natural gas
prices. The increase from the first quarter of 2013 was primarily the result of
the increase in realized natural gas prices, as well as gas cost allowance
adjustments in the first quarter of 2013. Natural gas royalties are anticipated
to average 4% to 6% of product sales for 2013. 


Offshore Africa 

Under the terms of the various Production Sharing Contracts, royalty rates
fluctuate based on realized commodity pricing, capital and operating costs, the
status of payouts, and the timing of liftings from each field. 


Royalty rates as a percentage of product sales averaged approximately 17% for
the second quarter of 2013 compared with 26% for the second quarter of 2012 and
16% for the first quarter of 2013. The decrease in royalties from the second
quarter of 2012 was due to adjustments to royalties on liftings during 2012. 


Offshore Africa royalty rates are anticipated to average 12% to 14% of product
sales for 2013.

(1) Amounts expressed on a per unit basis are based on sales volumes. 

North America 

North America crude oil and NGLs production expense for the six months ended
June 30, 2013 increased 3% to $14.72 per bbl from $14.23 per bbl for the six
months ended June 30, 2012. North America crude oil and NGLs production expense
for the second quarter of 2013 increased 13% to $14.83 per bbl from $13.10 per
bbl for the second quarter of 2012 and increased 2% from $14.61 per bbl for the
first quarter of 2013. The increase in production expense for the three and six
months ended June 30, 2013 from the comparable periods in 2012 was primarily the
result of higher electricity costs, as well as higher trucking costs related to
extended seasonal conditions in heavy oil production. The increase in production
expense for the second quarter of 2013 from the first quarter of 2013 was
primarily a result of higher electricity costs and extended spring season
conditions. North America crude oil and NGLs production expense guidance remains
unchanged from the previously issued guidance of $12.00 to $14.00 per bbl for
2013. 


North America natural gas production expense for the six months ended June 30,
2013 increased 17% to $1.45 per Mcf from $1.24 per Mcf for the six months ended
June 30, 2012. North America natural gas production expense for the second
quarter of 2013 increased 22% to $1.38 per Mcf from $1.13 per Mcf for the second
quarter of 2012 and decreased 9% from $1.52 per Mcf for the first quarter of
2013. Natural gas production expense increased for the three and six months
ended June 30, 2013 from the comparable periods in 2012 primarily due to higher
electricity costs along with lower production volumes related to the reduction
in natural gas activity. Natural gas production expense decreased for the second
quarter of 2013 from the first quarter of 2013 due to normal seasonality. North
America natural gas production expense is anticipated to average $1.35 to $1.40
per Mcf for 2013. 


North Sea 

North Sea crude oil production expense for the six months ended June 30, 2013
increased 20% to $60.38 per bbl from $50.21 per bbl for the six months ended
June 30, 2012. North Sea crude oil production expense for the second quarter of
2013 decreased 30% to $47.85 per bbl from $68.32 per bbl for the second quarter
of 2012 and decreased 36% from $74.65 per bbl for the first quarter of 2013.
Production expense increased on a per barrel basis for the six months ended June
30, 2013 from the comparable period due to the impact of production declines on
relatively fixed costs as well as higher maintenance activity and increased fuel
costs. Production expense decreased for the second quarter of 2013 from the
comparable periods due to increased production volumes on relatively fixed costs
and the timing of liftings from various fields, which have different cost
structures. North Sea crude oil production expense is anticipated to average
$62.00 to $66.00 per bbl for 2013 due to natural declines on a relatively fixed
cost structure. 


Offshore Africa 

Offshore Africa crude oil production expense for the six months ended June 30,
2013 increased 19% to $21.84 per bbl from $18.29 per bbl for the six months
ended June 30, 2012. Offshore Africa crude oil production expense for the second
quarter of 2013 averaged $17.98 per bbl, a decrease of 22% from $22.94 per bbl
for the second quarter of 2012, and a decrease of 30% from $25.72 per bbl for
the first quarter of 2013. Production expense fluctuated for the three and six
months ended June 30, 2013 from the comparable periods as a result of the timing
of liftings from various fields, which have different cost structures. Offshore
Africa crude oil production expense is anticipated to average $30.00 to $34.00
per bbl for 2013 due to timing of liftings from various fields, which have
different cost structures.

Depletion, depreciation and amortization expense increased for the three and six
months ended June 30, 2013 compared with 2012 due to higher sales volumes in
North America associated with heavy oil drilling and higher overall future
development costs. The decrease in depletion, depreciation and amortization
expense for the second quarter of 2013 from the first quarter of 2013 was
primarily due to lower sales volumes in North America.

OPERATING HIGHLIGHTS - OIL SANDS MINING AND UPGRADING 

OPERATIONS UPDATE 

The Company continues to focus on efficient and effective operations at Horizon
and place emphasis on safe, steady, reliable operations. In May 2013, the
Company successfully completed a planned maintenance turnaround. During the
outage, all major scopes of work were completed including the change out of the
catalysts in the hydro-treating units. Repairs to certain equipment extended
slightly beyond the original forecasted timeframe. The impact of the turnaround
has been reflected in the Company's 2013 production, cash production cost and
capital expenditure guidance.

The Company's stock option plan provides current employees with the right to
receive common shares or a direct cash payment in exchange for stock options
surrendered. 


The Company recorded a $22 million share-based compensation expense for the six
months ended June 30, 2013, primarily as a result of remeasurement of the fair
value of outstanding stock options at the end of the period related to an
increase in the Company's share price, together with the impact of normal course
graded vesting of stock options granted in prior periods and the impact of
vested stock options exercised or surrendered during the period. For the six
months ended June 30, 2013, the Company capitalized $5 million in respect of
share-based compensation expense to Oil Sands Mining and Upgrading (June 30,
2012 - $15 million recovery).

(1) Amounts expressed on a per unit basis are based on sales volumes.

Gross interest and other financing costs for the three and six months ended June
30, 2013 were consistent with the comparable periods. Capitalized interest of
$76 million for the six months ended June 30, 2013 was related to the Horizon
Phase 2/3 expansion and the Kirby Thermal Oil Sands Project, which includes the
Kirby South Project.


The Company's average effective interest rate for the three and six months ended
June 30, 2013 decreased from the comparable periods in 2012 primarily due to the
repayment of $400 million of 4.50% medium-term notes and US$400 million of 5.15%
unsecured notes during the first quarter of 2013 and US$350 million of 5.45%
unsecured notes in the fourth quarter of 2012. This indebtedness was retired
utilizing cash flow from operations generated in excess of capital expenditures
and available bank credit facilities, while maintaining the ongoing dividend
program. The Company's average effective interest rate for the second quarter of
2013 decreased from the first quarter of 2013 primarily due to an increase in
the utilization of the US commercial paper program during the second quarter of
2013.

(1) Amounts are reported net of the hedging effect of cross currency swaps.

The net realized foreign exchange gain for the six months ended June 30, 2013
was primarily due to foreign exchange rate fluctuations on settlement of working
capital items denominated in US dollars or UK pounds sterling and the repayment
of US$400 million of 5.15% unsecured notes in the first quarter of 2013. The net
unrealized foreign exchange loss for the six months ended June 30, 2013 was
primarily related to the impact of the weakening of the Canadian dollar with
respect to remaining US dollar debt and the reversal of the life-to-date
unrealized foreign exchange gain on the repayment of US$400 million of 5.15%
unsecured notes in the first quarter of 2013. The net unrealized (gain) loss for
each of the periods presented included the impact of cross currency swaps (three
months ended June 30, 2013 - unrealized gain of $86 million, March 31, 2013 -
unrealized gain of $49 million, June 30, 2012 - unrealized gain of $47 million;
six months ended June 30, 2013 - unrealized gain of $135 million; June 30, 2012
- unrealized gain of $5 million). The US/Canadian dollar exchange rate ended the
second quarter of 2013 at US$0.9513 (March 31, 2013 - US$0.9846; December 31,
2012 - US$1.0051; June 30, 2012 - US$0.9813).

(1) Includes North America Exploration and Production, Midstream, and Oil Sands
Mining and Upgrading segments.


(2) Excludes the impact of current and deferred PRT expense and other current
income tax expense.


The Company files income tax returns in the various jurisdictions in which it
operates. These tax returns are subject to periodic examinations in the normal
course by the applicable tax authorities. The tax returns as prepared may
include filing positions that could be subject to differing interpretations of
applicable tax laws and regulations, which may take several years to resolve.
The Company does not believe the ultimate resolution of these matters will have
a material impact upon the Company's results of operations, financial position
or liquidity. 


During the second quarter of 2013, the government of British Columbia
substantively enacted legislation to increase its provincial corporate income
tax rate effective April 1, 2013. As a result of the income tax rate change, the
Company's deferred income tax liability was increased by $15 million. 


For 2013, based on budgeted prices and the current availability of tax pools,
the Company expects to incur current income tax expense of $600 million to $700
million in Canada and $40 million to $100 million in the North Sea and Offshore
Africa.

(1) Net capital expenditures exclude adjustments related to differences between
carrying amounts and tax values, and other fair value adjustments.


(2) Capitalized interest and other includes expenditures related to land
acquisition and retention, seismic, and other adjustments.


(3) Abandonments represent expenditures to settle asset retirement obligations
and have been reflected as capital expenditures in this table.


The Company's strategy is focused on building a diversified asset base that is
balanced among various products. In order to facilitate efficient operations,
the Company concentrates its activities in core areas. The Company focuses on
maintaining its land inventories to enable the continuous exploitation of play
types and geological trends, greatly reducing overall exploration risk. By
owning associated infrastructure, the Company is able to maximize utilization of
its production facilities, thereby increasing control over production costs. 


Net capital expenditures for the six months ended June 30, 2013 were $3,528
million compared with $2,920 million for the six months ended June 30, 2012. Net
capital expenditures for the second quarter of 2013 were $1,792 million compared
with $1,324 million for the second quarter of 2012 and $1,736 million for the
first quarter of 2013. 


The increase in capital expenditures for the three and six months ended June 30,
2013 from the comparable periods was primarily due to the ramp up of Horizon
site construction activity and the increase in Horizon turnaround and sustaining
capital costs resulting from the planned maintenance turnaround in May 2013.


Subsequent to June 30, 2013, the Company acquired all of the issued and
outstanding common shares of Barrick Energy Inc. ("BEI") for total cash
consideration of approximately $173 million. BEI's assets include working
interests in producing crude oil and natural gas properties and undeveloped
land.

North America 

North America, excluding Oil Sands Mining and Upgrading, accounted for
approximately 57% of the total capital expenditures for the six months ended
June 30, 2013 compared with approximately 73% for the six months ended June 30,
2012. 


During the second quarter of 2013, the Company targeted 8 net natural gas wells,
including 6 wells in Northeast British Columbia and 2 wells in Northwest
Alberta. The Company also targeted 163 net crude oil wells. The majority of
these wells were concentrated in the Company's Northern Plains region where 121
primary heavy crude oil wells, 10 Pelican Lake heavy crude oil wells, and 27
bitumen (thermal oil) wells were drilled. Another 5 wells targeting light crude
oil were drilled outside the Northern Plains region. 


Overall Primrose thermal production for the second quarter of 2013 averaged
approximately 90,000 bbl/d compared with approximately 94,000 bbl/d for the
second quarter of 2012 and approximately 109,000 bbl/d for the first quarter of
2013. Production volumes were in line with expectations due to the cyclic nature
of thermal production at Primrose. As part of the phased expansion of its in
situ Oil Sands assets, the Company is continuing to develop its Primrose thermal
projects. Additional pad drilling was completed and drilled on budget, with
these wells coming on production in late 2013. 


In the second quarter of 2013, the Company discovered bitumen emulsion at
surface in areas of the Primrose field. The Company's view is that the cause of
the occurrence is mechanical in nature and is working collaboratively with the
regulators in the investigation and remediation plans. To minimize the risk of
any future occurrences while the investigation is being conducted, adjustments
were immediately made to the current steaming strategy and monitoring programs.
The Company does not currently expect a change in thermal in situ 2013 annual
production guidance. 


The next planned phase of the Company's in situ Oil Sands assets expansion is
the Kirby South Project. As at June 30, 2013, the overall project was 98%
complete, drilling was complete on all seven pads, and first steam is targeted
for the third quarter of 2013.


Development of the tertiary recovery conversion projects at Pelican Lake
continued and 10 horizontal wells were drilled during the second quarter of
2013. Pelican Lake production averaged approximately 42,000 bbl/d for the second
quarter of 2013 compared with 37,000 bbl/d for the second quarter of 2012 and
38,000 bbl/d for the first quarter of 2013. The new 20,000 bbl/d battery was
completed in mid-May, alleviating the previous facility constraints at Pelican
Lake and Woodenhouse. Field production is currently being optimized at both
Woodenhouse and Pelican Lake.


For the third quarter of 2013, the Company's overall planned drilling activity
in North America is expected to be 297 net crude oil wells, 47 net bitumen wells
and 9 net natural gas wells, excluding stratigraphic and service wells.


Oil Sands Mining and Upgrading 

Phase 2/3 expansion activity in the second quarter of 2013 was focused on field
construction of the gas recovery unit, sulphur recovery unit, butane treatment
unit, coker expansion, tank farms, tailings, hydrotransport and extraction
trains 3 and 4, along with engineering related to the froth treatment plants,
hydrogen unit, hydrotreater unit, vacuum distillation unit and distillation
recovery unit. 


North Sea 

In December 2011, the Banff FPSO and subsea infrastructure suffered storm
damage. Operations at Banff/Kyle, with combined net production of approximately
3,500 bbl/d, were suspended. The FPSO and associated floating storage unit were
subsequently removed from the field and the FPSO is currently undergoing repairs
and is targeted to be back in the field in the first half of 2014. The
associated repair costs, net of insurance recoveries, are not expected to be
significant. 


In September 2012, the UK government announced the implementation of the
Brownfield Allowance, which allows for an agreed allowance related to property
development for certain pre-approved qualifying field developments. This
allowance partially mitigates the impact of previous tax increases. The Company
received approval for the Brownfield Allowance for the Tiffany field in January
2013 and as a result, has commenced drilling additional production wells. During
the second quarter of 2013, the Company drilled one injector well and one
additional production well which came on at Tiffany, with production of
approximately 1,500 bbl/d, exceeding original forecasted volumes. In May 2013,
the Company received approval for the Ninian field Brownfield Allowance and will
commence drilling the second platform in the third quarter of 2013. 


During the second quarter of 2013, the Company also completed its consolidation
of a working interest in a satellite field at the Ninian hub. 


The Company currently plans to decommission the Murchison platform in the North
Sea commencing in 2014 and estimates the decommissioning efforts will continue
for approximately 5 years.


Offshore Africa 

During the fourth quarter of 2011, the Company sanctioned an 8 well drilling
program at the Espoir field in Cote d'Ivoire. Due to ongoing operational and
safety issues with the drilling contractor, the drilling rig currently on site
is being de-mobilized and the Company is assessing its drilling options at
Espoir. 


The midwater arch at the Olowi field in Gabon was stabilized and production was
reinstated in late March 2013. The final repairs and assessment have been made
and issues relating to the long-term operability of the midwater arch have been
resolved.

At June 30, 2013, the Company's capital resources consisted primarily of cash
flow from operations, available bank credit facilities and access to debt
capital markets. Cash flow from operations and the Company's ability to renew
existing bank credit facilities and raise new debt is dependent on factors
discussed in the "Risks and Uncertainties" section of the Company's December 31,
2012 annual MD&A. In addition, the Company's ability to renew existing bank
credit facilities and raise new debt is also dependent upon maintaining an
investment grade debt rating and the condition of capital and credit markets.
The Company continues to believe that its internally generated cash flow from
operations supported by the implementation of its ongoing hedge policy, the
flexibility of its capital expenditure programs supported by its multi-year
financial plans, its existing bank credit facilities, and its ability to raise
new debt on commercially acceptable terms will provide sufficient liquidity to
sustain its operations in the short, medium and long term and support its growth
strategy. 


The Company established a US commercial paper program in the first quarter of
2013. Borrowings of up to a maximum US$1,500 million are authorized. The Company
reserves capacity under its bank credit facilities for amounts outstanding under
this program. 


At June 30, 2013, the Company had $2,384 million of available credit under its
bank credit facilities, net of commercial paper issuances of $263 million. 


During the first quarter of 2013, the Company repaid $400 million of 4.50%
medium-term notes and US$400 million of 5.15% unsecured notes. The Company
retired this indebtedness utilizing cash flow from operations generated in
excess of capital expenditures and available bank credit facilities, while
maintaining the ongoing dividend program. 


During the second quarter of 2013, the $3,000 million revolving syndicated
credit facility was extended to June 2017. Additionally, the Company issued $500
million of 2.89% medium-term notes due August 2020. Proceeds from the securities
issued were used to repay bank indebtedness and for general corporate purposes.
After issuing these securities, the Company has $2,000 million remaining on its
outstanding $3,000 million base shelf prospectus that allows for the issue of
medium-term notes in Canada, which expires in November 2013. If issued, these
securities will bear interest as determined at the date of issuance. 


The Company has US$2,000 million remaining on its outstanding US$3,000 million
base shelf prospectus that allows for the issue of US dollar debt securities in
the United States, which expires in November 2013. If issued, these securities
will bear interest as determined at the date of issuance. 


Long-term debt was $10,033 million at June 30, 2013, resulting in a debt to book
capitalization ratio of 29% (March 31, 2013 - 28%; December 31, 2012 - 26%; June
30, 2012 - 26%). This ratio is within the 25% to 45% internal range utilized by
management. This range may be exceeded in periods when a combination of capital
projects, acquisitions, or lower commodity prices occurs. The Company may be
below the low end of the targeted range when cash flow from operating activities
is greater than current investment activities. The Company remains committed to
maintaining a strong balance sheet, adequate available liquidity and a flexible
capital structure. The Company has hedged a portion of its crude oil production
for 2013 and 2014 at prices that protect investment returns to ensure ongoing
balance sheet strength and the completion of its capital expenditure programs.
Further details related to the Company's long-term debt at June 30, 2013 are
discussed in note 6 to the Company's unaudited interim consolidated financial
statements. 


The Company's commodity hedge policy reduces the risk of volatility in commodity
prices and supports the Company's cash flow for its capital expenditure
programs. This policy currently allows for the hedging of up to 60% of the near
12 months budgeted production and up to 40% of the following 13 to 24 months
estimated production. For the purpose of this policy, the purchase of put
options is in addition to the above parameters. As at August 7, 2013,
approximately 58% of currently forecasted 2013 crude oil volumes were hedged
using price collars and physical crude oil sales contracts with fixed WCS
differentials. Further details related to the Company's commodity related
derivative financial instruments outstanding at June 30, 2013 are discussed in
note 13 to the Company's unaudited interim consolidated financial statements. 


Share Capital 

As at June 30, 2013, there were 1,086,969,000 common shares outstanding (June
30, 2012 - 1,096,497,000 common shares) and 67,463,000 stock options
outstanding. As at August 6, 2013, the Company had 1,087,477,000 common shares
outstanding and 66,328,000 stock options outstanding.


On March 6, 2013, the Company's Board of Directors approved an increase in the
annual dividend to be paid by the Company to $0.50 per common share for 2013.
The increase represents an approximately 19% increase from 2012, recognizing the
stability of the Company's cash flow and providing a return to shareholders. The
dividend policy undergoes periodic review by the Board of Directors and is
subject to change. 


In April 2013, the Company announced a Normal Course Issuer Bid to purchase
through the facilities of the Toronto Stock Exchange ("TSX") and the New York
Stock Exchange ("NYSE"), during the twelve month period commencing April 2013
and ending April 2014, up to 54,635,116 common shares. The Company's Normal
Course Issuer Bid announced in 2012 expired April 2013. 


For the six months ended June 30, 2013, the Company purchased 6,707,500 common
shares at a weighted average price of $30.86 per common share, for a total cost
of $207 million. Retained earnings were reduced by $184 million, representing
the excess of the purchase price of common shares over their average carrying
value. Subsequent to June 30, 2013, the Company purchased 230,000 common shares
at a weighted average price of $30.98 per common share for a total cost of $7
million.

(1) Long-term debt represents principal repayments only and does not reflect
fair value adjustments, original issue discounts or transaction costs.


(2) Interest and other financing cost amounts represent the scheduled fixed rate
and variable rate cash interest payments related to long-term debt. Interest on
variable rate long-term debt was estimated based upon prevailing interest rates
and foreign exchange rates as at June 30, 2013.


In addition to the commitments disclosed above, the Company has entered into
various agreements related to the engineering, procurement and construction of
subsequent phases of Horizon. These contracts can be cancelled by the Company
upon notice without penalty, subject to the costs incurred up to and in respect
of the cancellation.


LEGAL PROCEEDINGS AND OTHER CONTINGENCIES 

The Company is a defendant and plaintiff in a number of legal actions arising in
the normal course of business. In addition, the Company is subject to certain
contractor construction claims. The Company believes that any liabilities that
might arise pertaining to any such matters would not have a material effect on
its consolidated financial position. 


CHANGES IN ACCOUNTING POLICIES 

For the impact of new accounting standards, refer to the unaudited interim
consolidated financial statements for the six months ended June 30, 2013.


CRITICAL ACCOUNTING ESTIMATES 

The preparation of financial statements requires the Company to make estimates,
assumptions and judgments in the application of IFRS that have a significant
impact on the financial results of the Company. Actual results could differ from
estimated amounts, and those differences may be material. A comprehensive
discussion of the Company's significant critical accounting estimates is
contained in the MD&A and the audited consolidated financial statements for the
year ended December 31, 2012.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(tabular amounts in millions of Canadian dollars, unless otherwise stated,
unaudited)


1. ACCOUNTING POLICIES 

Canadian Natural Resources Limited (the "Company") is a senior independent crude
oil and natural gas exploration, development and production company. The
Company's exploration and production operations are focused in North America,
largely in Western Canada; the United Kingdom ("UK") portion of the North Sea;
and Cote d'Ivoire, Gabon, and South Africa in Offshore Africa. 


The Horizon Oil Sands Mining and Upgrading segment ("Horizon") produces
synthetic crude oil through bitumen mining and upgrading operations. 


Within Western Canada, the Company maintains certain midstream activities that
include pipeline operations, an electricity co-generation system and an
investment in the North West Redwater Partnership ("Redwater"). 


The Company was incorporated in Alberta, Canada. The address of its registered
office is 2500, 855-2 Street S.W., Calgary, Alberta, Canada. 


These interim consolidated financial statements and the related notes have been
prepared in accordance with International Financial Reporting Standards ("IFRS")
as issued by the International Accounting Standards Board ("IASB"), applicable
to the preparation of interim financial statements, including International
Accounting Standard ("IAS") 34, "Interim Financial Reporting", following the
same accounting policies as the audited consolidated financial statements of the
Company as at December 31, 2012, except as discussed in note 2. These interim
consolidated financial statements contain disclosures that are supplemental to
the Company's annual audited consolidated financial statements. Certain
disclosures that are normally required to be included in the notes to the annual
audited consolidated financial statements have been condensed. These interim
consolidated financial statements should be read in conjunction with the
Company's audited consolidated financial statements and notes thereto for the
year ended December 31, 2012.


2. CHANGES IN ACCOUNTING POLICIES 

Effective January 1, 2013, the Company adopted the following new accounting
standards issued by the IASB:


(a) - IFRS 10 "Consolidated Financial Statements" replaced IAS 27 "Consolidated
and Separate Financial Statements" (IAS 27 still contains guidance for Separate
Financial Statements) and Standing Interpretations Committee ("SIC") 12
"Consolidation - Special Purpose Entities". IFRS 10 establishes the principles
for the presentation and preparation of consolidated financial statements. The
standard defines the principle of control and establishes control as the basis
for consolidation, as well as providing guidance on applying the control
principle to determine whether an investor controls an investee. 


- IFRS 11 "Joint Arrangements" replaced IAS 31 "Interests in Joint Ventures" and
SIC 13 "Jointly Controlled Entities - Non-Monetary Contributions by Venturers".
The new standard defines two types of joint arrangements, joint operations and
joint ventures. In a joint operation, the parties with joint control have rights
to the assets and obligations for the liabilities of the joint arrangement and
are required to recognize their proportionate interest in the assets,
liabilities, revenues and expenses of the joint arrangement. In a joint venture,
the parties have an interest in the net assets of the arrangement and are
required to apply the equity method of accounting. 


- IFRS 12 "Disclosure of Interests in Other Entities". The standard includes
disclosure requirements for investments in subsidiaries, joint arrangements,
associates and unconsolidated structured entities. 


- The Company adopted these standards retrospectively. 

(b) IFRS 13 "Fair Value Measurement" provides guidance on applying fair value
where its use is already required or permitted by other standards within IFRS.
The standard includes a definition of fair value and a single source of fair
value measurement and disclosure requirements for use across all IFRSs that
require or permit the use of fair value. IFRS 13 was adopted prospectively. As a
result of adoption of this standard, the Company has included its own credit
risk in measuring the carrying amount of a risk management liability. 


(c) Amendments to IAS 1 "Presentation of Financial Statements" require items of
other comprehensive income that may be reclassified to net earnings to be
grouped together. The amendments also require that items in other comprehensive
income and net earnings be presented as either a single statement or two
consecutive statements. Adoption of this amended standard impacted presentation
only. 


(d) IFRS Interpretation Committee ("IFRIC") 20 "Stripping Costs in the
Production Phase of a Surface Mine" requires overburden removal costs during the
production phase to be capitalized and depreciated if the Company can
demonstrate that probable future economic benefits will be realized, the costs
can be reliably measured, and the Company can identify the component of the ore
body for which access has been improved. 


Adoption of these standards did not have a material impact on the Company's
consolidated financial statements.

In addition, the Company has capitalized costs to date of $1,320 million
(December 31, 2012 - $1,021 million) related to the development of the Kirby
Thermal Oil Sands Project which are not subject to depletion. 


The Company acquired a number of producing crude oil and natural gas assets in
the North American and North Sea Exploration and Production segments for total
cash consideration of $11 million during the six months ended June 30, 2013
(year ended December 31, 2012 - $144 million), net of associated asset
retirement obligations of $10 million (year ended December 31, 2012 - $12
million). Interests in jointly controlled assets were acquired with full tax
basis. No working capital or debt obligations were assumed. 


Subsequent to June 30, 2013, the Company acquired all of the issued and
outstanding common shares of Barrick Energy Inc. ("BEI") for total cash
consideration of approximately $173 million. BEI's assets include working
interests in producing crude oil and natural gas properties and undeveloped
land. Due to the timing of the close of the acquisition, the purchase accounting
and related disclosures have not been finalized.


The Company capitalizes construction period interest for qualifying assets based
on costs incurred and the Company's cost of borrowing. Interest capitalization
to a qualifying asset ceases once construction is substantially complete. For
the six months ended June 30, 2013, pre-tax interest of $76 million (June 30,
2012 - $39 million) was capitalized to property, plant and equipment using a
capitalization rate of 4.4% (June 30, 2012 - 4.8%).

Other long-term assets include an investment in the 50% owned Redwater. The
investment is accounted for using the equity method. Redwater has entered into
agreements to construct and operate a 50,000 barrel per day bitumen upgrader and
refinery (the "Project") under processing agreements that target to process
12,500 barrels per day of bitumen feedstock for the Company and 37,500 barrels
per day of bitumen feedstock for the Alberta Petroleum Marketing Commission, an
agent of the Government of Alberta, under a 30 year fee-for-service tolling
agreement. During 2012, the Project received board sanction from Redwater and
its partners. 


As at June 30, 2013, Redwater had interim borrowings of $353 million under
credit facilities totaling $600 million which mature no later than December
2017. These facilities are secured by a floating charge on the assets of
Redwater with a mandatory repayment required from future financing proceeds. At
maturity, under its processing agreement, the Company would be obligated to pay
its 25% pro rate share of any shortfall. 


Redwater has entered into various agreements related to the engineering and
procurement of the Project. These contracts can be cancelled by Redwater upon
notice without penalty, subject to the costs incurred up to and in respect of
the cancellation.

Bank Credit Facilities and Commercial Paper 

As at June 30, 2013, the Company had in place unsecured bank credit facilities
of $4,724 million, comprised of:

During the second quarter of 2013, the $3,000 million revolving syndicated
credit facility was extended to June 2017. Each of the $3,000 million and $1,500
million facilities is extendible annually for one-year periods at the mutual
agreement of the Company and the lenders. If the facilities are not extended,
the full amount of the outstanding principal would be repayable on the maturity
date. Borrowings under these facilities may be made by way of pricing referenced
to Canadian dollar or US dollar bankers' acceptances, or LIBOR, US base rate or
Canadian prime loans. 


The Company established a US commercial paper program in the first quarter of
2013. Borrowings of up to a maximum US$1,500 million are authorized. The Company
reserves capacity under its bank credit facilities for amounts outstanding under
this program.

commercial paper outstanding as at June 30, 2013, was 2.1% (June 30, 2012 -
1.9%), and on long-term debt outstanding for the six months ended June 30, 2013
was 4.4% (June 30, 2012 - 4.8%). 


In addition to the outstanding debt, letters of credit and financial guarantees
aggregating $560 million, including a $77 million financial guarantee related to

medium-term notes.

to repay bank indebtedness and for general corporate purposes. After issuing
these securities, the Company has $2,000 million remaining on its outstanding
$3,000 million base shelf prospectus that allows for the issue of medium-term
notes in Canada, which expires in November 2013. If issued, these securities
will bear interest as determined at the date of issuance.

11. CAPITAL DISCLOSURES 

The Company does not have any externally imposed regulatory capital requirements
for managing capital. The Company has defined its capital to mean its long-term
debt and consolidated shareholders' equity, as determined at each reporting
date. 


The Company's objectives when managing its capital structure are to maintain
financial flexibility and balance to enable the Company to access capital
markets to sustain its on-going operations and to support its growth strategies.
The Company primarily monitors capital on the basis of an internally derived
financial measure referred to as its "debt to book capitalization ratio", which
is the arithmetic ratio of current and long-term debt divided by the sum of the
carrying value of shareholders' equity plus current and long-term debt. The
Company's internal targeted range for its debt to book capitalization ratio is
25% to 45%. This range may be exceeded in periods when a combination of capital
projects, acquisitions, or lower commodity prices occurs. The Company may be
below the low end of the targeted range when cash flow from operating activities
is greater than current investment activities. At June 30, 2013, the ratio was
within the target range at 29%. 


Readers are cautioned that the debt to book capitalization ratio is not defined
by IFRS and this financial measure may not be comparable to similar measures
presented by other companies. Further, there are no assurances that the Company
will continue to use this measure to monitor capital or will not alter the
method of calculation of this measure in the future.

For the six months ended June 30, 2013 the Company recognized a gain of $3
million (December 31, 2012 - gain of $1 million) related to ineffectiveness
arising from cash flow hedges. 


Risk Management 

The Company uses derivative financial instruments to manage its commodity price,
foreign currency and interest rate exposures. These financial instruments are
entered into solely for hedging purposes and are not used for speculative
purposes. 


The estimated fair value of derivative financial instruments has been determined
based on appropriate internal valuation methodologies and/or third party
indications. Fair values determined using valuation models require the use of
assumptions concerning the amount and timing of future cash flows and discount
rates. In determining these assumptions, the Company primarily relied on
external, readily-observable market inputs including quoted commodity prices and
volatility, interest rate yield curves, and foreign exchange rates. The
resulting fair value estimates may not necessarily be indicative of the amounts
that could be realized or settled in a current market transaction and these
differences may be material. 


The changes in estimated fair values of derivative financial instruments
included in the risk management asset (liability) were recognized in the
financial statements as follows:

Financial Risk Factors

a) Market risk

Market risk is the risk that the fair value or future cash flows of a financial
instrument will fluctuate because of changes in market prices. The Company's
market risk is comprised of commodity price risk, interest rate risk, and
foreign currency exchange risk.


Commodity price risk management 

The Company periodically uses commodity derivative financial instruments to
manage its exposure to commodity price risk associated with the sale of its
future crude oil and natural gas production and with natural gas purchases. At
June 30, 2013, the Company had the following derivative financial instruments
outstanding to manage its commodity price risk:

----------------------------------------------------------------------------



(1) Subsequent to June 30, 2013, the Company entered into an additional 50,000
bbl/d of US$80.00 - US$118.26 WTI collars for the period August to December 2013
and an additional 50,000 bbl/d of US$80.00 - US$120.17 Brent collars for the
period January to December 2014. 


The Company's outstanding commodity derivative financial instruments are
expected to be settled monthly based on the applicable index pricing for the
respective contract month. 


Interest rate risk management 

The Company is exposed to interest rate price risk on its fixed rate long-term
debt and to interest rate cash flow risk on its floating rate long-term debt.
The Company periodically enters into interest rate swap contracts to manage its
fixed to floating interest rate mix on long-term debt. The interest rate swap
contracts require the periodic exchange of payments without the exchange of the
notional principal amounts on which the payments are based. At June 30, 2013,
the Company had no interest rate swap contracts outstanding. 


Foreign currency exchange rate risk management 

The Company is exposed to foreign currency exchange rate risk in Canada
primarily related to its US dollar denominated long-term debt, commercial paper
and working capital. The Company is also exposed to foreign currency exchange
rate risk on transactions conducted in other currencies in its subsidiaries and
in the carrying value of its foreign subsidiaries. The Company periodically
enters into cross currency swap contracts and foreign currency forward contracts
to manage known currency exposure on US dollar denominated debt, commercial
paper and working capital. The cross currency swap contracts require the
periodic exchange of payments with the exchange at maturity of notional
principal amounts on which the payments are based. At June 30, 2013, the Company
had the following cross currency swap contracts outstanding:




                                             Exchange

----------------------------------------------------------------------------
----------------------------------------------------------------------------



All cross currency swap derivative financial instruments designated as hedges at
June 30, 2013, were classified as cash flow hedges. 


In addition to the cross currency swap contracts noted above, at June 30, 2013,
the Company had US$2,643 million of foreign currency forward contracts
outstanding, with terms of approximately 30 days or less, including US$250
million designated as cash flow hedges.


b) Credit risk 

Credit risk is the risk that a party to a financial instrument will cause a
financial loss to the Company by failing to discharge an obligation.


Counterparty credit risk management 

The Company's accounts receivable are mainly with customers in the crude oil and
natural gas industry and are subject to normal industry credit risks. The
Company manages these risks by reviewing its exposure to individual companies on
a regular basis and where appropriate, ensures that parental guarantees or
letters of credit are in place to minimize the impact in the event of default.
At June 30, 2013, substantially all of the Company's accounts receivable were
due within normal trade terms. 


The Company is also exposed to possible losses in the event of nonperformance by
counterparties to derivative financial instruments; however, the Company manages
this credit risk by entering into agreements with counterparties that are
substantially all investment grade financial institutions and other entities. At
June 30, 2013, the Company had net risk management assets of $29 million with
specific counterparties related to derivative financial instruments (December
31, 2012 - $18 million).


c) Liquidity risk

Liquidity risk is the risk that the Company will encounter difficulty in meeting
obligations associated with financial liabilities. 


Management of liquidity risk requires the Company to maintain sufficient cash
and cash equivalents, along with other sources of capital, consisting primarily
of cash flow from operating activities, available credit facilities, commercial
paper and access to debt capital markets, to meet obligations as they become
due. The Company believes it has adequate bank credit facilities to provide
liquidity to manage fluctuations in the timing of the receipt and/or
disbursement of operating cash flows. 


The maturity dates for financial liabilities are as follows:



                                           1 to less   2 to less
