The field development concept includes a production vessel and an extensive subsea development, with a total of 30 wells distributed across 10 subsea templates and two satellite structures.

The production vessel is a FPSO with subsea solutions. The expected recoverable resources are estimated at 450—650 million barrels of oil equivalent.

Johan Castberg is a major subsea field and is important for potential further development and infrastructure in the Barents Sea.

New volumes have been discovered in the area. Five more discoveries are being considered tied in to Johan Castberg.

The Castberg partnership is planning for further exploration in the areas around the field in the years to come.

Snøhvit is a subsea gas and condensate field northwest of Hammerfest in northern Norway. Hammerfest LNG is a land plant on Melkøya that receives and processes the natural gas from Snøhvit through a 143 km long pipeline.

A total of 16 wells have been drilled on the Snøhvit field, 14 producers and two wells for re-injection of CO2. Approximately 700,000 tonnes of carbon dioxide (CO2) are captured and stored each year.

In May 2023, the authorities approved the Snøhvit Future Project, which includes the installation of a compression module on land and the electrification of the Melkøya facilities.

The project is well under way with expected completion in Q2 2028. The compression will help to maintain the production plateau from existing wells, while the electrification will reduce CO2 emissions in the order of 800,000 tonnes per year by closing the gas power plant.
