EnQuest assumes full decommissioning control over North Sea GKA project

EnQuest says the partners in the Greater Kittiwake Area (GKA) complex in the UK central North Sea are working to extend the lives of the various satellite fields.

At the same time, planning continues for cessation of production, including well P&A while the GKA platform continues operations. Last August, Shell transferred its remaining GKA decommissioning operator role to EnQuest.

In the northern UK North Sea, the company’s Heather field team completed all Phase 1 and Phase 2 well P&A work last December. Parallel rig campaigns continue on the Heather platform and at Thistle nearby, where the team is deploying a third system to recover conductors.

So far 24 wells at Thistle have been fully abandoned.

At the EnQuest-operated Magnus field in the East Shetland basin, an unplanned outage of the Magnus subsea isolation valve within the 500-m zone of the Ninian Central platform led recently to a shut-in of all system users, including Magnus.

However, production was reinstated within a few days following a collaborative effort by all the system users, with EnQuest managing the operation to repair the subsea hydraulic system.

At the Sullom Voe Terminal on Shetland, work continues on a new stabilization facility that will support future planned new energy projects in the region.
