Revision in reserves at the Yme field

Revision in reserves at the Yme field

(Trondheim, 4 October 2023): OKEA ASA (OSE: OKEA) ("OKEA" or the "Company").

Following observation of production performance from the wells drilled at the

Yme field earlier this year, OKEA has performed a decline analysis of the field.

The preliminary results indicate a reduction in reserves net to OKEA from 7.6

Mmboe (adjusted ASR 2022) to an expected range of 5.5-6.5 Mmboe. OKEA will

engage with the license partners to further explore the results of the analysis

and undertake a revised lifetime assessment of the Yme field.

As the Yme asset is held at fair value in the Company's financial statements, an

impairment is expected in the third quarter of 2023. Further information on the

impairment will be provided in the Company's trading update planned for

publication on 19 October 2023.
