The Norwegian Petroleum Safety Authority said Thursday that it will investigate a gas leak at Statoil’s Gudrun field.
The leak was detected on Wednesday and production at the field was shut down and the facility was depressurized.
The size of the leak is currently unknown.
There were 26 people on board the Gudrun facility when the leak occurred and 97 people at the nearby West Epsilon mobile drilling facility.
No injuries were reported.
“The objects of the investigation include clarifying the chain of events and identifying proximate and underlying causes,” the PSA said.
The field produced 4.6 million cubic meters of gas per day, 821 cubic meters of condensate and 1,410 cubic meters of NGL in November, according to the Norwegian Petroleum Directorate.
Statoil holds a 51 percent operating stake in the field.
France’s GDF Suez holds a 25 percent stake and Austria-based OMV holds a 24 percent stake.
