The Oselvar field is located in the Production licence 274 in the southern part of the Norwegian sector in the North Sea, 20km south-west of the Ula field.

Production from the field was sent to the Ula platform for gas separation and injection in the host field reservoir whereas the liquid was sent to Teeside via Ekofisk.

Situated at a water depth of 70m, the field commenced production in 2012 and was shut down in May 2018, due to its inefficiency to live up to its initial expectations.

Decommissioning of the field is planned to be completed by the end of 2022, as per the formal disposal resolution.
