P1916 Offshore Isle of Wight Licence Extension, Wessex-Weald Basin, UK

UK Oil & Gas Investments PLC (LSE AIM/ISDX: UKOG) announces that UKOG Solent Limited, a 100%-owned subsidiary, has been advised that the Oil and Gas Authority has granted a one-year extension to the Initial Term of the Company's offshore P1916 licence to 31^st January 2018. The Company holds a 100% interest in P1916.

As previously reported by the Company, P1916 contains an undrilled Portland limestone conventional oil prospect, which is a look-alike to the nearby Arreton Portland oil discovery, located in the Company's adjacent PEDL331 onshore licence. A deeper Triassic sandstone prospect lies directly beneath the Portland target in P1916.

The company plans to submit a planning application to drill one or more prospects in the Isle of Wight during the coming year.

Stephen Sanderson, UKOG's Executive Chairman, commented:

"UKOG's future planned Isle of Wight operations are aimed solely at the extraction of oil from conventional naturally-fractured limestone and sandstone reservoirs, not shale, and therefore will not utilise massive hydraulic fracturing.

Our drilling on the island is intended to cause zero hazards to any groundwater by employing the same drilling fluids and practices used by the water supply industry to drill drinking-water abstraction wells within the UK's limestone aquifers. This drilling technology is intended to include the use of modern biodegradable drilling fluids, manufactured from 100% natural plant starches, which are approved for use under the UK's Water Supply Regulations."

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:

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
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 reservoirs	a petroleum reservoir rock containing tectonically induced open fractures, joints and fissures which are filled with petroleum. The petroleum filled fractures can provide essential reservoir porosity and permeability, essential permeability only, or provide a permeability enhancement alone. Such reservoirs have been created over geological time by nature, not man-made via hydraulic fracturing
prospect	a project associated with a potential accumulation that is sufficiently well defined to represent a viable drilling target
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
shale	a laminated and fissile very fine-grained sedimentary rock, consisting of compacted silt and clay-size mineral particles. Can contain high proportions of organic material, which if subjected to heat and pressure over geological time can generate petroleum (a petroleum source rock)
starch	starch is a carbohydrate of a general formula (C₆H₁₀O₅)n and is derived from corn, wheat, oats, rice, potatoes, yucca and similar plants and vegetables.
