EnQuest details well performance measures on North Sea fields
EnQuest expects to bring three new wells onstream later this year at the Magnus oil field in the UK northern North Sea, following an upgrade of the Magnus platform drilling rig.
The company, which acquired operatorship of the field from BP in 2017, also plans logging and well interventions to improve performance.
In the same region, EnQuest is lining up infill drilling on the Heather field and low-cost well abandonments at both Heather and Thistle.
Production from the company’s Alma/Galia fields in the UK central North Sea dipped last year due to a combination of electric submersible pump (ESP)-related well shut-ins, storm-inflicted production outages, and natural declines.
EnQuest has been addressing these and other issues with projects to optimize power, produced water and sea water injection, and the company has commissioned a workover program to replace certain ESPs during 2018.
Production from Scolty/Crathes (satellite tiebacks to the Greater Kittiwake Area facilities) has been constrained by wax in the flowline. Chemical treatments are keeping the flowline operational while the partners consider rectification measures.
Early this year, EnQuest re-negotiated terms for the drilling rig serving theKraken heavy-oil field development in the UK northern North Sea, which began production last year.
It has managed to reduce both the contract duration and day rates, saving around $60 million in capex payments for 2019.
Full cycle gross capex for Kraken is now set to be roughly $2.3 billion, over 25% lower than the originally sanctioned figure. The DC4 (fourth drill center) well campaign should get under way during the second half of 2018.
Offshore Peninsular Malaysia, EnQuest will drill two wells this year on the PM8/Seligi fields, both of which should start production later in 2018.
