OKEA NorthSea

OKEA, alongside its partners, has announced a petroleum discovery at the 'Knockando Fensfjord' prospect in the North Sea.

The well was drilled from the Brage installation as part of a development well for oil (31/4-A-15 D) within production licence 055, according to the Norwegian Offshore Directorate.

Preliminary estimates suggest that, if the discovery contains oil, it could add between 0.5 and 1.5 million standard cubic metres (Sm³) of recoverable oil equivalent (o.e.) to Brage’s resources. If the find is gas, estimated volumes range from 0.4 to 0.9 million Sm³ o.e.

Well 31/4-A-15 D recently began production from the 31/4-A-1 B 'Talisker' discovery on 11 January 2026. The licence holders are now evaluating potential development options for the Knockando Fensfjord discovery.

Production licence 055 was awarded in Norway’s fourth licensing round on the Norwegian continental shelf (NCS) in 1978. The Brage field was proven in 1980, with the plan for development and operation (PDO) approved by the Storting in 1990. Several new discoveries have been made in the Brage area in recent years, including “Talisker Cook/Statfjord” (31/4-A-15 B) and “Prince” (31/4-A-23 G), both confirmed in 2025.

The current licensees in production licence 055 include OKEA (operator), Lime Petroleum, DNO, Petrolia NOCO, and M Vest Energy.

The development well 31/4-A-15 D targeted the lower Fensfjord Formation of Late Jurassic age en route to the “Talisker” production target in the Middle Jurassic Brent Group. The well confirmed a 38.5-metre hydrocarbon column across multiple sandstone layers with moderate to good reservoir quality. The petroleum-water contact was not encountered.

The well reached measured and vertical depths of 10,009 metres and 2,309 metres below sea level, respectively, before being terminated in the Oseberg Formation of the Middle Jurassic. Geological and reservoir data were collected throughout the discovery interval.

This latest find adds to OKEA and its partners’ ongoing efforts to optimise resource recovery in the Brage area, further strengthening the field’s contribution to Norway’s oil production.
