The Enoch field could remain shut until the middle of this year as the ongoing technical problems which have left it closed for two years continue.
The field, which straddles the UK and Norwegian borders 160 miles off Aberdeen, was closed at the end of January 2012 after mechanical issue with the subsea equipment on the site.
The Talisman operated field was originally due to restart late last year, but now field partner Noreco has warned it could be the middle of summer before it finally resumes production.
“The Enoch field which was closed for maintenance almost two years ago will most likely remain shut well into the second quarter this year,” the company warned in a statement last night.
At peak production, the field is expected to produce around 15,000barrels of oil equivalent, which is processed at Brae Alpha 10 miles away. The field was first developed in 2007.
The news came as Noreco revealed it had been boosted by the output from the Huntington field.
The field, which was shut in for several days over Christmas due to weather conditions, has returned to full operations after the technical problems which cut output last year.
Noreco said production had reached more than 32,000 barrels of oil equivalent per day.
