Production at the Breagh gas field, one of the biggest in the North Sea, resumed on December 27 following a shutdown in November.
The shutdown came just one month after operations started, project stakeholder Sterling Resources said in a statement on Monday.
The launch of the field was plagued by delays and equipment issues have added to the series of problems since it opened for production in mid-October.
The field is majority owned by German RWE Dea.
“Sterling Resources is pleased to announce the restart of Breagh production on December 27, 2013. This follows a period of approximately seven weeks shut-in as a result of a significant production incident on November 7th,” the company said in a statement.
The Breagh field is expected to produce around 112 million cubic feet per day in 2014, and will pump gas to Britain’s Teesside onshore gas processing terminal.
Sterling Resources also said that Breagh already has two planned shutdowns scheduled for the first week of January 2014.
