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 13⅜ 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 12¼ 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 km² 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.

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 fractured reservoir	a fractured reservoir contains open and usually connected cracks 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.
