Equinor has struck oil in exploration well 7720/7-DD-1H, Drivis Tubåen, on the Johan Castberg field in the Barents Sea, it said on Monday.
The well was drilled in the Drivis structure on the Johan Castberg field in the Barents Sea. According to preliminary estimates, the size of the discovery is 9-15 million barrels of oil.
“The Johan Castberg volume base originally estimated at 450–650 million barrels, our clear ambition is to increase the reserves by another 250–550 million barrels. To realise this, we are planning six new exploration wells and continuous exploration activity,” says Grete Birgitte Haaland, Equinor’s senior vice president for Exploration & Production North.
Equinor also plans to develop Isflak as a rapid field expansion with planned start-up in 2028.
The oil was proven in a new segment called the Tubåen formation 1769 metres below the seabed in 345 metres of water. The well was drilled by the Transocean Enabler drilling rig as an exploratory extension from a production well. The licensees will consider tie-in of the discovery to the Johan Castberg field.
