At peak, Johan Castberg can produce 220,000 barrels of oil per day, and recoverable volumes are estimated at between 450 and 650 million barrels.

“This is a red-letter day. The Johan Castberg field will contribute crucial energy, value creation, ripple effects, and jobs for at least 30 years to come. We expect that this major field development with a price tag of NOK 86 billion (2024) will be repaid in less than two years,” said Geir Tungesvik, Equinor’s Executive Vice President for Projects, Drilling, and Procurement.

Twelve of the 30 wells are ready for production, which is sufficient to bring the field up to the expected plateau production in the second quarter of 2025.

“Johan Castberg opens a new region for oil recovery and will create more opportunities in the Barents Sea. We’ve already made new discoveries in the area and will keep exploring together with our partners. We’ve identified options to add 250–550 million new recoverable barrels that can be developed and produced over Johan Castberg,” said Kjetil Hove, Equinor’s Executive Vice President for Exploration & Production Norway.

The field’s supply base and helicopter base are in Hammerfest and will be operated from Equinor’s office in Harstad. A total of 30 wells will be drilled on the Johan Castberg field, and drilling operations are expected to continue towards late 2026, which will yield significant activity in Hammerfest.

“Johan Castberg has been a massive and challenging project, and I want to extend my very sincere thanks to everyone who contributed on the road leading to first oil and operation, both our partners Vår Energi and Petoro, our suppliers and our own employees. Seventy-nine million hours of work have been recorded in the project, and the HSE results are very good. Now, the field will produce for 30 years and generate substantial values,” Tungesvik said.
