    Development
    Johan Castberg is a field in the Barents Sea, 100 kilometres northwest of the Snøhvit field. The water depth is 370 metres. Johan Castberg consists of the three discoveries Skrugard, Havis and Drivis, proven between 2011 and 2013. The plan for development and operation (PDO) was approved in 2018. The discoveries were developed together, and the development concept is a production, storage and offloading vessel (FPSO) with additional subsea templates including 18 horizontal production wells and 12 injection wells.
    02.04.2025
    Reservoir
    The reservoirs contain oil with gas caps in three separate sandstone deposits of Late Triassic to Middle Jurassic age in the Tubåen, Nordmela and Stø Formations. They are at depths of 1250-1900 metres. Reservoir properties in the Tubåen and Stø Formations are generally good; the Nordmela Formation is more heterogeneous with several lateral barriers.
    02.04.2025
    Recovery strategy
    The field is produced by pressure support from gas and water injection.
    02.04.2025
    Transport
    The oil is offloaded to shuttle tankers and transported to the market.
    02.04.2025
    Status
    The production started in March 2025.
