The Johan Castberg oil field is an offshore petroleum development in the Barents Sea on Norway’s continental shelf, operated by Equinor. Located about 240 km northwest of Hammerfest, it is one of the northernmost producing fields in Norway. The project achieved first oil on 31 March 2025 and reached peak production of around 220,000 barrels per day on 17 June 2025, less than three months after start-up, becoming a significant contributor to Norway’s crude output.
The field is developed around a Floating Production, Storage and Offloading (FPSO) vessel linked to 30 subsea wells across 10 templates. Recoverable reserves are estimated at 450–650 million barrels of oil, with an expected operational life of around 30 years, and drilling of the remaining planned wells is expected to continue through late 2026. Johan Castberg is operated by Equinor with a 46.3 stake, alongside partners Vår Energi (30 ) and Petoro (23.7 ).
The field was officially opened on 8 August 2025 by Norway’s Minister of Energy. In December 2025, the partners approved an investment of more than NOK 4 billion to tie back the Isflak discovery to the Johan Castberg hub, with start-up planned for Q4 2028. Offshore logistics and safety coverage are supported by helicopter services, including a NOK 1.9 billion contract awarded on 2 February 2026 to Bristow for helicopter transportation and search and rescue operations in the Barents Sea through at least 2029, while additional nearby discoveries such as Drivis Tubåen and the Skred prospect are being evaluated for future tie-backs.
