Statoil shut in production at its Gudrun oil and gas field in the Norwegian North Sea Wednesday after a gas leak was detected.
The Norway-based company does not know when output from the field will restart, Reuters said.
Statoil has not disclosed the cause or the size of the gas leak.
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.
