    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 discoveries will be developed together, and the plan for development and operation (PDO) was approved in June 2018. The development concept is a production, storage and offloading vessel (FPSO) with additional subsea solutions including 18 horizontal production wells and 12 injection wells.

    Reservoir
    The reservoirs contain oil with gas caps in three separate sandstone deposits from Late Triassic to Middle Jurassic age in the Tubåen, Nordmela and Stø Formations. The reservoirs are located at depths of 1,350 to 1,900 metres. Reservoir properties in the Tubåen and Stø Formations are generally good; the Nordmela Formation is more heterogeneous with several lateral Barriers.
    17.12.2021
    Recovery strategy
    The field will be produced by pressure support from gas and water injection.
    25.04.2019
    Transport
    The oil will be offloaded to shuttle tankers and transported to the market.
    25.04.2019
    Status
    The field is currently under development, and production is scheduled to start in 2024.
