OKEA discovers oil near North Sea Brage field

OKEA ASA discovered oil near Brage oil field in production license (PL) 055 in the North Sea, the Norwegian Petroleum Directorate said in a release Oct. 26. About 0.2-0.5 million std cu m of recoverable oil reserves were proven.

Two wells were drilled from the platform on Brage field in 137 m of water. Well 31/4-A 13 E was drilled as a horizontal sidetrack based on data collected during the drilling operation. The well encountered the Sognefjord formation 2,147 m subsea and proved oil in a sandstone layer of about 10 m in reservoir rocks with moderate to good reservoir quality. The oil-water contact was not encountered.

Production well 31/4-A-13 D was drilled in the southern part of Brage field and was extended to reach two exploration targets in a separate structure south of the field. The targets were in Sognefjord and Fensfjord formations, and both were dry. The well was not formation-tested, but data acquisition has been carried out. The well has been plugged.

Brage field was proven in 1980 in reservoir rocks in the Statfjord and Brent Group and in the Fensfjord and Sognefjord formations. 

The field started production in 1993 and comprises a production, drilling, and quarters platform with oil transportation via the Oseberg Transport System-Sture Terminal and gas offtake through Gassco AS’s Gassled pipeline system on the Norwegian continental shelf (OGJ Online, Oct. 9, 2023).

OKEA is operator at PL 055 (35.2%) with partners Lime Petroleum AS (33.8434%), DNA Norge AS (14.2567%), Petrolia (12.2575%), and M Vest Energy AS (4.4423%).
