LONDON – EnQuest is progressing decommissioning activities at various field centers in the UK North Sea.
The company is working with its partners and the UK regulator to secure approval for cessation of production (CoP) at the Dons fields during 2Q 2021.
Production has been impacted by a lack of gas lift, which used to be supplied from Thistle (shut down earlier this year).
Following approval for the Thistle/Deveron CoP application, the decommissioning phase has started, with preservation visits to the Thistle platform ahead of a planned well abandonment program next year.
At Heather, in the same region, FEED is progressing ahead of the resumption of well abandonments in 2021.
And following CoP at Alma/Galia in the central North Sea this summer, the FPSO EnQuest Producer moved off station in September and is currently moored alongside the oil terminal jetty at Nigg, northeast Scotland. EnQuest is assessing future options for the floater.
At Magnus in the East Shetland basin, the company has resolved sea water lift pump system issues. The focus continues on activities to improve production, including well interventions reservoir management, and gas compression optimization.
Magnus has remaining 2C resources of around 38 MMbbl and close to 250 MMbbl of movable oil to evaluate.
At the Kraken heavy-oil field, subsurface and well performance remains good and the company is working on improved injector-producer well management. Water cut rate evolution remains stable.
EnQuest is examining further near-field opportunities via development of the western area, which holds an estimated 70-130 MMbbl of in place oil.
As for the agreement announced in July to acquire a 40.81% share from Equinor in the undeveloped Bressay heavy-oil field, EnQuest has been approved to become operator and well abandonment activities that Equinor had planned have been completed.
Bressay, with potential 2C resources to EnQuest of up to 115 MMbbl, could be developed via a phased subsea tieback to Kraken.
