Key Highlights
- OKEA discovered oil in the Talisker exploration well Brage field in the North Sea.
- The licensees are considering tying it back to Brage.
OKEA ASA discovered oil in Talisker exploration well 31/4-A-15 B in production license (PL 055) near Brage field in the North Sea, where the license partners are considering a tieback. The Norwegian Offshore Directorate provided additional details about the exploration well in a Sept. 11 release.
The well was drilled from the Brage platform to 10,223 m MD and 2,759 m TVD subsea. It was terminated in the Lunde formation in the Upper Triassic. The objective was to prove petroleum in Lower Jurassic reservoir rocks in the Cook formation and the Statfjord group.
The well encountered 25 m of oil in the Cook formation in sandstone layers totaling 52.4 m with moderate reservoir properties. The oil-water contact was not encountered.
In the Statfjord group, the well encountered 63 m of oil in a total of 171 m of sandstone with moderate-to-good reservoir properties. The oil-water contact was encountered at 2,616 m subsea.
The preliminary estimated size of the discoveries is 0.3-1.11 million std cu m of oil equivalent (2-7 million bbl) in the Cook formation and 2.2-4.1 million std cu m of oil equivalent (14-26 million bbl) in the Statfjord group in the Talisker area.
The well was not formation-tested, but data collection and sampling have been carried out. The well has been plugged.
Appraisal of hydrocarbons encountered in the Brent group is expected to be completed during fourth-quarter 2025.
OKEA ASA is operator of the license with 35.2% interest. Partners are Lime Petroleum AS (33.8434%), DNO Norge AS (14.2567%), Petrolia NOCO AS (12.2575%), and M Vest Energy AS (4.4424%).
