Further Update on Horse Hill-1 Flow Test

Second Zone Continues flowing Oil at a Rate of 838 Barrels Per Day

Following the announcement on 01 March 2016, UK Oil & Gas Investments PLC (London AIM and ISDX: UKOG) announces that Horse Hill Developments Limited ("HHDL") has informed the Company that the well resumed flowing 100% dry oil from the Upper Kimmeridge Limestone, through a one-inch choke, at an instantaneous rate of 1008 barrels per day ("bopd") and continued to flow for a further 7.5 hours from 2234hrs on 29 February at an average rate of 838 bopd. The well was shut in at 0600 01 March for a 12-hour pressure build up test.

As previously announced, on completion of this Upper Kimmeridge test, operations will move to the shallower Portland sandstone zone at approximately 615 metres below ground level.

Horse Hill-1 Discovery Well and Licence

The exploration drilling phase of the HH-1 discovery well was originally completed at the end of 2014. The well is located within onshore exploration Licence PEDL137, on the northern side of the Weald Basin near Gatwick Airport. UKOG owns a 19.968% interest in PEDL137.

Stephen Sanderson, UKOG's Executive Chairman commented:

"The well continues to perform above management's expectations. We look forward to testing the overlying Portland shortly."

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 0.72% interest in HHDL via its 6% interest in Angus Energy Limited.

Glossary

choke	a device incorporating a fixed or variable orifice that is used to control fluid flow rate during testing of an exploratory discovery
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
