ABERDEEN, UK – EnQuest has issued updates on its incremental field development programs in the UK North Sea.
At Thistle/Deveron in the UK northern North Sea, two new cranes have been installed and made operational as part of the platform/field life extension program. The B turbine was recommissioned and returned to service.
At Dons in the same sector, the “TJ” well in Area 22 of Don Southwest was tied-in in August, while a scale dissolver program at Don Southwest appears to have been successful. The water injection system is being upgraded.
Following development approval from the government for development of the Ythan field, adjacent to Don Southwest in the southern area of the Don North East license, EnQuest plans to start drilling soon, with first production to follow by mid-2015.
A new injection well (H64) came online in July at Heather in the northern North Sea. However, a water injection flowline at Broom failed at the end of August. Replacement options are under evaluation for implementation during 1H 2015.
In September, the Mallard workover was completed and the well brought back online, with the existing tree reinstalled. Mallard is one of the fields tied into the Greater Kittiwake Area (GKA) complex that the company acquired recently from previous operator Centrica.
Another workover is under way at Gadwall where production is expected to be reinstated in mid-2015, following side tracking of the existing well. EnQuest claims to have reduced opex/bbl at the GKA significantly, with further reductions to come in 2015. Additionally, front-end engineering and design studies are nearing completion on a new tie-in of the Scolty/Crathes fields.
Early next year the company plans to drill the Eagle exploration well.
As for new field development projects, a pre-first oil drilling program has been completed for the Alma production wells, with five wells now available to come onstream in mid-2015, followed by a water injector on Alma at the end of 2015. The subsea infrastructure is in place, with risers and mooring systems awaiting the arrival of the FPSO.
The heavy-oil Kraken development remains on track for start-up in 2017. The drilling rig is expected to arrive at the field by next summer to start a four-year contract.
As for Bumi Armada’s work on the FPSO, the early focus has been on the hull conversion and the marine system refurbishment. Two integrated subsea templates have been installed at the first drill center, and eight wellheads have been delivered. A survey vessel has completed coring work at the FPSO mooring anchor locations.
Finally, EnQuest says it has been offered eight licenses under the UK 28th North Sea Licensing Round.
