Donnybrook Energy Inc.: Bigstone 13-33 Well Production Tubing Installed

Donnybrook Energy Inc. ("Donnybrook" or the "Company") (TSX VENTURE:DEI) reports
that production tubing string has now been installed in the DEI Bigstone Hz
13-33-60-22 W5M Montney well (DEI 25%) and that the well is now ready for tie-in
to the Company operated Bigstone pipeline system. Construction of surface
facilities and 1,300 metres pipeline installation is anticipated to commence in
mid October with an estimated on-stream date of early November 2012.


The well was flowed back after installation of the tubing string. The average
flow rate during the final 24 hours of a limited flow back production test
period totaling 32 hours and 15 minutes, was 2.87 mmcf/day (DEI net 0.72 mmcf/d)
and 510 bbls/day (DEI net 128 bbls/day) of condensate and load fluid.
Approximately 75% of the load fluid used during fracing operations has been
recovered to date. The 13-33 well was drilled to a total measured depth of 5,336
metres with a lateral length of approximately 2,600 metres and completed with a
23 stage frac. 


At Bigstone, Donnybrook has 8 gross sections (2,048 ha) 3.75 net sections (960
ha) of P&NG rights located approximately 35 kilometres (22 miles) east of the
eastern edge of the Company's Simonette acreage block.


Donnybrook holds interests in 46 gross (22.9 net) sections of petroleum and
natural gas rights in the Bigstone-Simonette-Resthaven liquid rich natural gas
resource play in the Deep Basin area of west central Alberta.

FORWARD-LOOKING STATEMENTS

This press release contains forward-looking statements or information
("forward-looking statements") within the meaning of applicable securities laws
including statements regarding the timing of the construction and completion of
the surface facilities and pipeline installation for the Bigstone 13-33 well.
The use of any of the words "will", "expects", "believe", "plans", "potential"
and similar expressions are intended to identify forward-looking statements. 


The forward-looking statements in this press release are based on certain key
expectations and assumptions made by Donnybrook, including the quality of the
Montney reservoir, continued performance from existing wells, future drilling
programs and performance from new wells, the growth of infrastructure, well
density per section, recovery factors and that development necessarily involves
known and unknown risks and uncertainties. Although Donnybrook believes that the
expectations and assumptions on which such forward-looking statements are based
are reasonable, undue reliance should not be placed on the forward-looking
statements because Donnybrook can give no assurance that they will prove to be
correct. There is no certainty that Donnybrook will achieve commercially viable
production from its undeveloped lands and prospects.


Since forward-looking statements address future events and conditions, by their
very nature, they involve inherent risks and uncertainties. Actual results could
differ materially from those currently anticipated due to a number of factors
and risks. These include, but are not limited to the risks associated with the
oil and gas industry in general such as: operational risks in development,
exploration and production; delays or changes in plans with respect to
exploration or development projects or capital expenditures; the uncertainty of
reserve estimates; the uncertainty of estimates and projections relating to
reserve, production, costs and expenses; health, safety and environmental risks;
commodity price and exchange rate fluctuations; marketing and transportation of
petroleum and natural gas and loss of markets; environmental risks; competition;
incorrect assessment of the value of acquisitions; failure to realize the
anticipated benefits of acquisitions; ability to access sufficient capital from
internal and external sources; stock market volatility; and changes in
legislation, including but not limited to tax laws, royalty rates and
environmental regulations. Readers are cautioned: (i) the foregoing list of
factors is not exhaustive; and (ii) not to place undue reliance on
forward-looking statements. Additional information on these and other factors
that could affect the operations or financial results of Donnybrook are included
in Donnybrook's Annual Information Form, management's discussion and analysis
and other documents filed with applicable securities regulatory authorities and
may be accessed through the SEDAR website (www.sedar.com). The forward-looking
statements contained in this press release are made as of the date hereof and
Donnybrook undertakes no obligation to update publicly or revise any
forward-looking statements, whether as a result of new information, future
events or otherwise, unless so required by applicable securities laws. The
forward-looking statements contained in this press release are expressly
qualified by this cautionary statement. 


Where amounts are expressed on a barrel of oil equivalent ("BOE") basis, natural
gas volumes have been converted to oil equivalence at six thousand cubic feet
per barrel. The term BOE may be misleading, particularly if used in isolation. A
BOE conversion ratio of six thousand cubic feet per barrel is based on an energy
equivalency conversion method primarily applicable at the burner tip and does
not represent a value equivalency at the wellhead. References to oil in this
discussion include crude oil and natural gas liquids ("NGLs"). NGLs include
condensate, propane, butane and ethane. References to gas in this discussion
include natural gas. 


The reader is cautioned that the well test results disclosed in this press
release are not necessarily indicative of long-term performance or of ultimate
recovery.
