Production from Statoil's Sleipner East and West fields in the North Sea has been halted for the next few weeks to permit a major turnaround.
The Sleipner A, B and T platforms shut down on the evening of 14 August, with the first of these units due to resume production after 20 days and the other two after 24 days.
A process train for Sleipner condensate at Statoil's Kårstø treatment complex north of Stavanger has also been closed down for maintenance during this period.
Gas delivery commitments from Sleipner are being met by other fields during the shutdown, reports turnaround coordinator Sven Tømmerås.
Sleipner West cut back production by about 25 per cent a week before the stoppage to permit modifications and improvements to the carbon dioxide separation plant, he explains.
Part of Sleipner A is to be modified because reservoir pressure is sinking as gas and condensate are produced. This shift to low-pressure production includes modifications to wells, inlet separators and recompression facilities.
The previous turnaround on Sleipner A was two years ago, while the B and T platforms also had a maintenance shutdown in 1999.
