OKEA ASA discovered petroleum in the Knockando Fensfjord prospect in the North Sea and is considering development opportunities with partners.
The well was drilled from the Brage platform, and the discovery was made in connection with drilling a development well for oil (31/4-A-15 D) in production licence 055, the Norwegian Offshore Directorate said in a release Jan. 28.
Brage has been in production since 1993, and efforts are being made to increase recovery from the field. New oil and gas discoveries have been made in the Brage area in recent years. Talisker Cook/Statfjord (31/4-A-15 B) and Prince (31/4-A-23 G) were proven in 2025.
Knockando Fensfjord prospect
Well 31/4-A-15 D was drilled to 10,009 m MD and 2,309 m TVD subsea. It was terminated in the Oseberg formation in the Middle Jurassic. The well was drilled into the reservoir section in the lower Fensfjord formation of Late Jurassic age on its way to the Talisker production target in the Brent Group of Middle Jurassic age.
A 38.5-m column of hydrocarbons was proven in an interval of multiple sandstone layers with moderate to good reservoir quality. The petroleum-water contact was not encountered, and data was collected in the discovery interval.
Preliminary estimates indicate additional Brage resources of 0.5-1.5 million std cu m of recoverable oil equivalent if the discovery is oil. If it is gas, the preliminary volume estimate is 0.4-0.9 million std cu m of oil equivalent.
The well started producing from the 31/4-A-1 B Talisker discovery on Jan. 11, 2026.
OKEA is operator of PL 055 (35.2%) with partners Lime Petroleum AS (33.8%), DNO Norge AS (14.2%), Petrolia NOCO AS (12.2%), and M Vest Energy AS (4.4%).
