OKEA and its partners have announced a petroleum discovery in the Knockando Fensfjord prospect in the Norwegian North Sea, identified through development well 31/4-A-15 D from the Brage installation. Brage is located in the northern section of the North Sea, positioned approximately 10km to the east of the Oseberg field, in a water depth of 140m. The Brage field was discovered in 1980 and has been in production since September 1993. Preliminary assessments suggest that the discovery may contribute additional resources to the Brage field, with estimates ranging from 500,000 to 1.5 million standard cubic metres (mscm) of oil equivalent, if oil is present.
