Description
Description TypeTextDate updatedDevelopmentVest Ekofisk is a field in the southern part of the Norwegian sector in the North Sea, five kilometres west of the Ekofisk field. The water depth is 70 metres. Vest Ekofisk was discovered in 1970. The original plan for development and operation (PDO) was approved in 1973, and production started in 1977. The field was developed with a combined drilling, production and living quarters facility. Vest Ekofisk was shut down in 1998, and the facility was removed in 2012. A PDO for the redevelopment of Vest Ekofisk was approved in 2026. The development concept includes a subsea template with three wells tied back to the Ekofisk Centre.08.05.2026ReservoirThe reservoir contains oil and gas from fractured chalk of Late Cretaceous age in the Tor Formation and of early Paleocene age in the Ekofisk Formation. The reservoir is at a depth of 3200 metres above a salt dome.08.05.2026Recovery strategyThe field will be produced by pressure depletion.08.05.2026TransportThe well stream will be transported via pipeline to the Ekofisk Complex for further export.08.05.2026StatusThe field is under development, and the production is planned to start in 2028.08.05.2026 -
