Turkish Energy Ministry grants formal drilling consent for Basur-3 appraisal well

UK Oil & Gas PLC (London AIM: UKOG) is delighted to announce that the Turkish Ministry of Energy and Natural Resources ("Ministry") has granted UKOG Turkey and Aladdin Middle East formal consent to drill the forthcoming Basur-3 appraisal well, located in the Resan licence AR/AME-UKO/K/M47-b1, b2 ("Licence"). UKOG Turkey, a wholly owned UKOG subsidiary, has a 50% interest in the Licence, which contains the potentially significant Basur-Resan oil discovery.

The Ministry's permission, dated 2^nd April 2021, follows the partnership's 1^st April 2021 submission of the required Pre-Activity Information Form (Annexe-50) and Drilling Programme. The consent requires the Ministry to be notified 5-days prior to the actual spud date of Basur-3.

Drilling pad and access road construction works continue to progress ahead at good pace with completion expected by end May.

As detailed in the Company's announcements of 14^th October 2020, January 15^th and 23^rd March 2021, Basur-3 is the first key step towards establishing the commerciality of the Basur-Resan Mardin oil pool, calculated to contain potentially transformational discovered recoverable oil resources (see: glossary below and Turkey presentations of January 15^th and 23^rd March 2021 on https://www.ukogplc.com ).

Stephen Sanderson UKOG's Chief Executive commented:

"The speedy grant of drilling consent from the Turkish government further illustrates how oil and gas projects can be pushed ahead more rapidly and with more certainty in Turkey than in the UK onshore, a key enabler for value creation and preservation. We commend our partner Aladdin Middle East's efforts in this respect."

Glossary

discovered recoverable volumes/resources (or contingent resources)	those quantities of discovered petroleum estimated, as of a given date, to be recoverable from a known accumulation, but where the project is not yet considered proven for commercial development due to one or more contingencies. In the case of Basur-Resan the contingency being confirmation that a well can recover a commercial volume at commercially viable rates, a normal appraisal stage uncertainty. Discovered resources are further categorised in accordance with the level of certainty associated with the estimates and may be sub-classified based on project maturity and/or characterised by their economic status. Should the Basur-Resan appraisal programme confirm commerciality, it is expected that resources would convert into reserves (see reserves definition below)
discovery	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
reserves	those quantities of petroleum anticipated to be commercially recoverable by application of development projects to known accumulations from a given date forward under defined conditions. Reserves must further satisfy four criteria: they must be discovered, recoverable, commercial, and remaining (as of the evaluation date) based on the development project(s) applied. Reserves are further categorised in accordance with the level of certainty associated with the estimates (i.e., Proven, Probable and Possible) and may be sub-classified based on project maturity and/or characterised by development and production status
