Drilling Update at 100% Owned Broadford Bridge-1 Kimmeridge Exploration Well

PEDL234 Licence, Weald Basin, UK

UK Oil & Gas Investments PLC (London AIM and NEX: UKOG) announces that 133/8 inch steel casing was set and cemented successfully over the 855 feet thick Weald Clay section on its 100% interest Broadford Bridge-1 ("BB-1") Kimmeridge Limestone exploration well. Directional drilling operations, within 12 1/4 diameter hole, commenced on Monday evening. BB-1 has now reached a depth of over 370 metres (1200 feet) below surface within the Lower Cretaceous Hastings Beds. The uppermost Kimmeridge Limestone target, KL4, is expected to be conventionally cored in around 10-12 days' time. The well remains on schedule and within budget.

About BB-1

BB-1 is located near Billingshurst, West Sussex, within the 300 km(2) PEDL234 licence, in which the Company has a 100% interest via its ownership of the licence's operator, Kimmeridge Oil & Gas Limited. The well, an exploration step-out, is designed to penetrate four naturally fractured Kimmeridge Limestone units (KL1-KL4), the uppermost two units of which flowed at record rates in the Company's Horse Hill-1 discovery near Gatwick Airport.

The well is designed to drill through the target limestones at an inclination of around 50 degrees to vertical and at approximately 90 degrees to the predicted orientation of open natural fractures in the reservoir. The planned overall horizontal deviation of the well is approximately 1 km to the north-northeast of the well site. The Kimmeridge Limestones are expected to be encountered at a drilled depth of approximately 1300-1700 metres, which equates to around 950-1200 metres vertically below surface.

Qualified Person's Statement

Stephen Sanderson, UKOG's Executive Chairman, who has over 35 years of relevant experience in the oil industry, has approved the information contained in this announcement. Mr Sanderson is a Fellow of the Geological Society of London and is an active member of the American Association of Petroleum Geologists.

Glossary:

 
 casing           heavy gauge steel tubing designed 
                   to line the wall of a well. The 
                   casing provides a safe controlled 
                   space in which the drill pipe and 
                   bit can operate in isolation from 
                   conditions in overlying rock units. 
                   The steel tubing is bonded to the 
                   surrounding rock by impermeable 
                   concrete, known as "cement". 
---------------  ------------------------------------------ 
 core or coring   a drilling technique that involves 
                   using a doughnut-shaped drilling 
                   bit to capture or "cut" a continuous 
                   cylinder-shaped core of undamaged 
                   in-situ rock. The core is captured 
                   in a steel pipe or "core barrel" 
                   above the bit. Core is normally 
                   cut in 30 feet lengths, or multiples 
                   of 30 feet, and normally with a 
                   diameter of 3.5 or 4 inches. Core 
                   is taken in petroleum reservoir 
                   rocks for detailed laboratory analyses 
                   of petrophysical and geomechanical 
                   parameters. 
---------------  ------------------------------------------ 
 discovery        a discovery is a petroleum accumulation 
                   for which one or several exploratory 
                   wells have established through 
                   testing, sampling and/or logging 
                   the existence of a significant 
                   quantity of potentially moveable 
                   hydrocarbons 
---------------  ------------------------------------------ 
 electric logs    tools used within the wellbore 
                   to measure the rock and fluid properties 
                   of surrounding rock formations 
---------------  ------------------------------------------ 
 limestone        a sedimentary rock predominantly 
                   composed of calcite (a crystalline 
                   mineral form of calcium carbonate) 
                   of organic, chemical or detrital 
                   origin. Minor amounts of dolomite, 
                   chert and clay are common in limestones. 
                   Chalk is a form of fine-grained 
                   limestone 
---------------  ------------------------------------------ 
 naturally        a fractured reservoir contains 
  fractured        open and usually connected cracks 
  reservoir        or fissures within the rock matrix; 
                   fractures can enhance permeability 
                   of rocks greatly by connecting 
                   pore-spaces together; naturally 
                   fractured reservoirs have been 
                   created over geological time by 
                   nature, not man-made via hydraulic 
                   fracturing 
---------------  ------------------------------------------ 
 step-out well    a well specifically designed to 
                   determine the lateral extent of 
                   a discovered hydrocarbon accumulation 
                   or play.
