Production resumed on the Åsgard B platform in the Norwegian Sea in the early hours of Friday 20 January. The Statoil-operated Mikkel field is also producing again.
The Kristin field, also operated by Statoil, is preparing to start up again soon.
And gas exports from the Statoil-operated Heidrun field are in full swing. The gas is sent via the Åsgard Transport line.
Åsgard B's production was shut down on 15 January after sparks and smoke appeared in an exhaust system in one of the export compressors.
Condensate and gas exports from Kristin and Mikkel were subsequently halted, as was all export of gas from Heidrun via the Åsgard Transport line.
Statoil's gas customers have not been affected by the production shortfall.
