UK Oil & Gas Investments PLC ("UKOG" or the "Company")

Acquisition of Additional Interest in PEDL143, Holmwood Prospect, Weald Basin, UK

UK Oil & Gas Investments PLC (London AIM and ISDX:UKOG) announces that it has executed a farm- in agreement with Warwick Energy Exploration and Production Limited ("Warwick") to acquire a further 10% interest in UK onshore Weald Basin licence PEDL143 ("Licence") which contains the Holmwood Prospect. This second farm-in increases UKOG's interest in the Licence to 30%. As previously reported, the Company will participate in the drilling of the planned Holmwood-1 exploration well which will test the Holmwood Prospect's identified Portland sandstone, Kimmeridge limestone and Corallian sandstone reservoir objectives.

PEDL143 covers 35.5 square miles and is located to the immediate west of Horse Hill licence PEDL137, in which UKOG has a 20.163% interest, and to the immediate south of the Brockham oil field, licence PL235, in which UKOG has an interest via its 6% ownership of Angus Energy Limited.

Further details of PEDL143 prospectivity are available on the Company's website www.ukogplc.com

Transaction details:

Subject to receipt of the necessary consent from the Oil and Gas Authority ("OGA"), UKOG will pay a consideration of £25,000 and a 20% share of the Holmwood-1 exploration drilling costs in order to acquire a full 10% working interest in PEDL143 from Warwick.

UKOG's 20% share of well costs will be capped at £0.6 million net to UKOG (i.e. 20% of a gross Holmwood-1 well cost estimate of £3 million). Gross well costs above £3 million, should they arise, will be met by UKOG, Warwick and other partners pro-rata according to their working interests in PEDL143.

Stephen Sanderson, UKOG's Executive Chairman commented:

"We are delighted to follow up our very recent news on the OGA's consent to the Egdon PEDL143 farm-in with the acquisition of a further interest in the Licence from Warwick. These two transactions now provide the Company with a material 30% overall participating interest in the Holmwood exploration well and Licence.

With this acquisition the Holmwood well now provides an excellent low to moderate risk opportunity for UKOG to access a mean estimated 1.68 million barrels of net conventional prospective resources together with the opportunity to confirm the Kimmeridge tight oil in place within the Licence as calculated by Nutech in their recent study of the Company's licences and wider Weald.

We look forward to working with the partnership and to drilling the Holmwood-1 well next winter. "

GLOSSARY

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
mean	or expected value, is the probability-weighted average of all possible values and is a measure of the central tendency either of a probability distribution or of the random variable characterised by that distribution
oil in place	the quantity of oil or petroleum that is estimated to exist originally in naturally occurring accumulations before any extraction or production
prospect	a project associated with a potential accumulation that is sufficiently well defined to represent a viable drilling target
prospective resources	those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects; potential accumulations are evaluated according to their chance of discovery and, assuming a discovery, the estimated quantities that would be recoverable under defined development projects. It is recognised that the development programs will be of significantly less detail and depend more heavily on analogue developments in the earlier phases of exploration
reservoir	a subsurface rock formation containing an individual natural accumulation of moveable petroleum that is confined by impermeable rock/formations
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.
tight oil	oil found or expected to be present within a reservoir with low permeability, i.e. a tight reservoir. The term, in the case of the Weald Tight Oil Plays, is applied to a

play where trapped petroleum accumulations are expected to be pervasive throughout a large area and that are not significantly affected by hydrodynamic influences (also called "continuous-type deposits")
