"Clearly we are very disappointed with this turn of events at Breagh, as it further delays production from the field," he said in a statement Wednesday.
Sterling, which has headquarters in Canada, said RWE Dea, the German operator of the field, shut it down to resolve "a number of mechanical issues." Repairs should take about two weeks, Sterling said.
"We are still at an early stage in the investigation and will inform the market when a clearer picture of the extent of necessary repairs emerges," Rapach said. "We will continue to work closely with the operator RWE Dea in order to resolve the issues and resume production as quickly as possible."
There was no corresponding statement on the shutdown from RWE.
RWE announced Oct. 14 production from the Breagh field in British waters of the North Sea started with a flow rate of 97 million cubic feet of gas per day.
RWE said it estimates the field holds as much as 699 billion cubic feet of natural gas reserves.
