(Trondheim, 25 August 2025) OKEA ASA (OSE: OKEA) announces oil discoveries in
the Talisker exploration well at the Brage field (PL 055). The discoveries were
made in the Cook and Statfjord formations and are considered commercial with
preliminary estimates of gross recoverable resources in the range of 16 - 33
mmboe combined. In addition, appraisal of hydrocarbons encountered in the Brent

The Talisker exploration well (31/4-A-15 B), a 10.223 meter long well, was
drilled from the Brage platform in the North Sea. Discoveries were made in the
Cook and Statfjord formations and are considered commercial with preliminary
estimates of gross recoverable resources in the range of 2 - 7 mmboe in the Cook
formation and 14 - 26 mmboe in the Statfjord formation respectively. In
addition, hydrocarbons were encountered in two thin sandstones in the Brent
group which will be further appraised by the upcoming well paths, expected
completed during Q4 2025.

"This discovery is another example of OKEA's strategy to utilise existing
infrastructure, subsurface knowledge and drilling technology to unlock more
value in the Brage area, and extend the lifetime of the field", says Svein J.
Liknes, CEO of OKEA.

More information on the final well result will be published by the Norwegian
