Further Update on Flow Test

Horse Hill-1 Oil Discovery, Weald Basin, UK

Further Significant Oil Flows to Surface from Lower Kimmeridge Limestone

Following the announcement on 16 February 2016, UK Oil & Gas Investments PLC (London AIM and ISDX: UKOG) announces that Horse Hill Developments Limited ("HHDL") has informed the Company that light, 40-degree API, sweet oil has continued to flow naturally to surface from an 80-foot zone within the Lower Kimmeridge limestone interval at a depth of approximately 900 metres below ground level.

Flow re-commenced at around 07.45 am GMT yesterday at a steady oil rate in excess of 456 barrels of oil per day over a further 9.5-hour period using a smaller 28/64-inch choke in order to further stabilise the flow. Yesterday's flow consisted of dry oil with zero water.

As previously announced, Phase 2 and Phase 3 operations will move to the shallower Upper Kimmeridge limestone and Portland sandstone zones at approximately 840 and 615 metres below ground level, respectively, once the Lower Kimmeridge testing is completed.

The HH-1 discovery well, the original exploration drilling phase originally completed at the end of 2014, is located within onshore exploration Licence PEDL137, on the northern side of the Weald Basin near Gatwick Airport. UKOG owns a 20.163% interest in PEDL137.

Stephen Sanderson, UKOG's Executive Chairman commented:

"The well continues to produce high quality oil at good rates. Although further work is required to be done, we are now beginning to establish the commerciality of the project earlier than originally anticipated. The first two tankers full with 348 barrels of oil were sent to be refined at noon yesterday."

UKOG's interest in Horse Hill

The HH-1 well is located within onshore exploration Licence PEDL137, on the northern side of the Weald Basin near Gatwick Airport. UKOG owns a 30% direct interest in HHDL and a 1.02% interest in HHDL via its 6% interest in Angus Energy Limited. HHDL is a special purpose company that owns a 65% participating interest and operatorship of Licence PEDL137 and the adjacent Licence PEDL246 in the UK Weald Basin.

Glossary

choke	Device incorporating a fixed or variable orifice that is used to control fluid flow rate during testing of an exploratory discovery
degree API	A measure of the density of crude oil as defined by the American Petroleum Institute
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
extended flow test	a flow test, as per the permission granted by the Oil and Gas Authority, with an aggregate flow period duration over all zones of greater than 96 hours and up to 90 days maximum.
flow test	a flow test or well test involves testing a well by flowing hydrocarbons to surface, typically through a test separator. Key measured parameters are oil and gas flow rates, downhole pressure and surface pressure. The overall objective is to identify the well's capacity to produce hydrocarbons at a commercial flow rate
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
sandstone	a clastic sedimentary rock whose grains are predominantly sand-sized. The term is commonly used to imply consolidated sand or a rock made of predominantly quartz sand.
sweet oil or crude	A type of oil that contains less than 0.42% Sulphur
