Equinor has made an oil discovery that will be tied into the Johan Castberg field in the Barents Sea.
The discovery was made in the “Polynya Tubåen” prospect (7220/7-5). The well was drilled by the COSL Prospector rig. The preliminary volume estimate is between 14 and 24 million barrels of recoverable oil equivalents.
The volume basis in Johan Castberg was originally estimated at 500–700 million barrels, and Equinor has an ambition to increase this by an additional 200–500 million barrels.
