    Development
    Vest 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, and the plan for development and operation (PDO) was approved in 1973. The field was developed with a combined drilling, production and living quarters facility. The production started in 1977. From 1994, the Vest Ekofisk 2/4 D facility was remotely controlled from Ekofisk 2/4 T.
    09.12.2023
    Reservoir
    Vest Ekofisk produced 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.
    09.12.2023
    Recovery strategy
    The field was produced by pressure depletion.
    28.02.2023
    Transport
    The well stream was transported via pipeline to the Ekofisk Complex for further export to Emden in Germany and Teesside in the UK.
    28.02.2023
    Status
    Vest Ekofisk was shut down in 1998, and the facility was removed in 2012. The field is currently being evaluated for redevelopment in combination with other decommissioned fields in the area.
