March 27, 2026

OKEA has raised its estimate of the recoverable resource in last year’s Talisker West discovery in the Norwegian North Sea from 19 MMboe to 28 MMboe.

This follows further studies of the Talisker Statfjord Formation. OKEA added that the plan of development, which involves drilling and production directly from the Brage platform, is unchanged, with an anticipated breakeven cost of below $10/bbl.

It has also increased its combined recoverable volume estimates from the Statfjord and Cook formations from 16-33 MMboe to 23-44 MMboe.

Talisker West is 10 km east of the Oseberg Field and 120 m west of Bergen. The wellbore for the discovery was drilled to an MC of 10,223 m using the drilling rig onboard the Brage platform.

OKEA expects first oil in 2027. Other partners in the license are Lime Petroleum, DNO Norge, Petrolia NOCO and M Vest Energy.
