Turkey: Pinarova-1 Testing Update

UK Oil & Gas PLC (London AIM: UKOG) is pleased to announce that following the temporary suspension of Pinarova-1 testing operations, larger and more powerful 7-inch perforating guns, capable of fully penetrating Pinarova-1's 9⅝-inch casing and cement and that are available for import into Turkey, have now finally been sourced. The Company is working closely with the Pinarova-1 operator, Aladdin Middle East, to facilitate delivery to the site as soon as possible so as testing operations can recommence.

As per the Company's 23^rd May 2023 RNS, downhole pressure gauge data showed that the original 4.5-inch perforating guns, the only size guns available in-country, did not establish direct contact with the formation. Therefore, tests to date did not assess the potential of the zones associated with the 12 hours of strong crude oil odour and oil at surface as previously reported on 3^rd May 2023.

Additionally, new geochemical analyses undertaken by UK/Norway based APT Ltd demonstrate  that both the Pinarova mud-pit oil sample and oil samples from the nearby shallow seismic shot-hole seep are a geochemical close match and most likely originate from the same Mesozoic age oil source rock, located beneath the general area of the shallow Pinarova structure.

With this in mind, should further testing be positive, consideration is being given to the acquisition of a small 3D seismic programme to identify a possible deeper oil pool, seepage/spill from which being the most likely primary source of both the seep and Pinarova oils.

Pinarova-1, located 6 km north of the Basur-1 oil discovery, was designed to test a working hypothesis, supported by well and seismic data, that the active 42˚ API light oil seep found last summer in a seismic shot hole above the Pinarova structure, is directly fed by and connected to an underlying light oil accumulation lying within the Germik and/or Hoya limestones.

UKOG holds a 50% non-operated interest in Pinarova-1 and the surrounding 305 km² Resan licence, which also includes the as yet undeveloped Basur-1 light oil discovery.

Glossary

°API	a measure of the density of crude oil, as defined by the American Petroleum Institute
discovery	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
oil seep	a natural flow of crude oil at or close to the earth's surface whose origin is from a petroleum accumulation or oil source rock at depth.
oil shows	The presence of visible moveable oil on drill cuttings and or within the drilling fluid seen at surface
shot hole	a shallow borehole in which a small amount of explosive is detonated in order to generate a seismic signal
source rock	a sedimentary rock, usually a claystone, mudstone or shale, which contains fossil organic matter known as kerogen derived from the decomposition of fossil phytoplankton, algae, bacteria and occasionally plant material. When the kerogen is subjected to increasing temperature and pressure through burial over geological time, it is transformed into hydrocarbons.
