Johan Castberg is a large oil field with estimated recoverable volumes of between 450 and 650 million barrels. The field will produce for 30 years, and at its peak, Johan Castberg may produce 220,000 barrels per day. The field development concept includes 30 wells distributed across ten subsea templates and two satellites that will now be tied back to the FPSO. So far, 13 of these wells have been drilled, and drilling operations will continue into 2026.
Johan Castberg is located 240 kilometers northwest of Hammerfest. The field has a supply and helicopter base in Hammerfest and an operations organization in Harstad.
“Johan Castberg is important for our development plans in Northern Norway. When the field comes on stream, a new province will be opened for oil recovery in the Barents Sea. This provides new opportunities for the exploration and development of new discoveries in the area. Working with our partners, we are already maturing five discoveries towards a possible tie-in to Johan Castberg,” says Grete Birgitte Haaland, Equinor’s senior vice president for Northern Norway.
The Norwegian supply industry has accounted for more than 70 percent of the total deliveries to the Johan Castberg project. In the operating phase, 95 percent of deliveries are expected to come from Norwegian suppliers. The North Norwegian content is estimated at about 40 percent, and every third of Johan Castberg employees lives in Northern Norway.
