Turkey: Pinarova-1 Testing Update

UK Oil & Gas plc (London AIM: UKOG) is pleased to announce that Aladdin Middle East, the Pinarova-1 operator, has advised that the resumption of testing operations within the Germik/Hoya sequence, utilising larger and more powerful 7-inch perforating guns, capable of fully penetrating the well's 9?-inch casing, is expected in around 4 weeks once the guns are on site.

Testing will cover the section where strong oil odours at surface were recorded over a 12-hour period during drilling and mobile light oil was recovered from the mud pit. Subsequent geochemical analysis revealed that the Pinarova mud pit oil is near identical to and from the same source rock as the 42? API seismic shot hole oil seep, located around 1.5 km to the west (see RNS of 22nd September 2023).

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.

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.
