Normal operation was restored on the Statoil-operated Grane field in the North Sea on 18 October, ending a substantial reduction in output since early October.
The cut-back was caused by problems with the gear shaft on the platform’s injection compressor following an extensive overhaul of this equipment during a planned turnaround in September.
As soon as the difficulties were encountered, an action team was appointed to find a solution. The project resulted in a return to normal operation several weeks earlier than expected.
Grane produced some 30,000 barrels of oil per day during the slow-down, or roughly 20% of normal output.
The field is now back to its normal daily flow of roughly 150,000 barrels, of which Statoil’s share is 36.66%.
