A drilling campaign has boosted production at CNOOC International’s Golden Eagle field in the UK North Sea.
Chinese operator CNOOC said four infill wells were drilled using the Noble Sam Hartley heavy duty jack-up drilling rig.
The campaign began in August 2020 and the fourth well came on stream earlier this month.
CNOOC said it delivered the project early, under budget and with no reportable HSE incidents.
The four wells, which are located in the central area of the field, exceeded subsurface expectations and have added significant, immediate production, it said.
Craig Paveley, vice president, developments, at CNOOC International, said: “We are delighted with the Golden Eagle infill campaign which was completed safely, ahead of schedule and under budget.
“This is testament to the expertise and efforts of everyone involved, offshore and onshore, who have delivered excellent results throughout the challenging conditions of the COVID-19 pandemic.”
The Golden Eagle area, located about 70 miles north-east of Aberdeen, produced first oil in October 2014.
London-listed EnQuest is buying Canadian firm Suncor’s 26.69% stake in the area.
EnQuest said the purchase would give it additional production of 10,000 barrels of oil equivalent per day and reserves of 18 million barrels.
