- Equinor, Vår Energi, and Petoro invest over NOK 4 billion in Johan Castberg's first subsea tie-back.
- The new development targets 46 million barrels of recoverable oil, starting Q4 2028.
- Johan Castberg currently produces 220,000 barrels per day, with potential for 250-550 million more recoverable barrels.
- Equinor plans 75 subsea developments, focusing on efficient collaboration with partners and authorities.
Investment and Development
Equinor, Vår Energi, and Petoro are investing over NOK 4 billion in the first subsea development tied to the Johan Castberg field in the Barents Sea. This decision follows eight months after the field began production. The new development aims to recover an estimated 46 million barrels of oil, with operations expected to start in the fourth quarter of 2028.
Infrastructure and Efficiency
The rapid development is facilitated by utilizing standardized solutions from Johan Castberg, as the reservoir is within the same license and similar to previous discoveries. This approach allows for the reuse of equipment and well solutions, enhancing efficiency and reducing costs. The Johan Castberg field, which started production in March, currently produces 220,000 barrels per day and serves as a hub for future developments in the area.
Future Prospects
There is potential to add 250-550 million new recoverable barrels to Johan Castberg. The partnership is planning six new wells for improved oil recovery and will continue exploration in the area. A recent discovery in the Drivis Tubåen segment is under evaluation for quick production integration.
Strategic Planning
Equinor aims to maintain production levels on the Norwegian continental shelf from 2020 to 2035, despite declines in current fields. This will be achieved through new wells and projects, with approximately 75 subsea developments planned. The Isflak discovery will involve two wells in a new subsea template, connected to existing facilities, and Equinor has applied for regulatory confirmations to proceed efficiently.
