Update on year-end 2022 oil reserves

Genel Energy plc ('Genel') today updates on oil reserves across its portfolio.

International petroleum consultants DeGolyer and MacNaughton, working on behalf of the operator DNO, assess that Tawke licence (Genel 25% working interest) gross year-end 2022 2P reserves stood at 327 MMbbls, compared to 357 MMbbls at year-end 2021, after adjusting for production of 39 MMbbls and an upward technical revision of 9 MMbbls. Following implementation and observation of the performance of phase 1 of the Tawke field Enhanced Oil Recovery project, Genel has moved 11.7 MMbbls of the 23.3 MMbbls of those gross 2P reserves that were previously included as 2C resources into 2P reserves.

At Taq Taq (44% working interest, joint operator), gross 2P reserves stood at 24 MMbbls at year-end 2022 (26 MMbbls at end-2021), following production of 1.6 MMbbls. McDaniel & Associates carried out the independent assessment of the Taq Taq licence.

At Sarta (30% working interest, operator) Genel’s estimate of gross 2P reserves at year-end 2022 is 9 MMbbls (32 MMbbls at the end of 2021), following production of 1.7 MMbbls and a technical revision after assessment of the results of the 2022 appraisal wells and pilot production.
