Verus Petroleum has completed a deal with Equinor for its stake in the Alba field in the North Sea.
The deal, for an undisclosed sum, sees Verus take a 17% interest in the Chevron-operated development.
Equinor said its share of production from Alba last year was around 2,300 barrels per day.
Other partners include Chevron, Endeavour Energy UK, Mistui E&P, Spirit Energy, EnQuest and EQ Petroleum Sabah.
Equinor is retaining its share of decommissioning liability for the field, while Verus will be liable for any new Alba facilities.
The field facilities include the Alba Northern Platform, and a floating production unit.
