LONDON (Reuters) - Britain’s North Sea Buzzard oilfield has been fully shut down since Wednesday morning for repairs, a statement from the field operator said on Thursday.
The 150,000 barrel-per-day field is operated by Nexen, a subsidiary of China’s CNOOC.
The field was shut earlier this month for about 10 days for repairs.
“A defect on topsides pipework was repaired last week and production safely restarted. A routine follow-up inspection identified that the integrity of the repair was subsequently compromised,” the statement said.
“An alternative repair option is being progressed.”
Buzzard plays a role in global oil pricing as it is the main contributor to the Forties crude stream, the largest of the five North Sea oil grades that underpin the Brent crude oil futures benchmark LCOc1.
