Production on the Oseberg field center, Oseberg South, Oseberg East and Tune has resumed after the small fire in a switchboard room on the Field Centre on June 15.
The field centre and the three other fields associated with the field centre's processing plant have been shut down during the cleaning and repairs of the switchboard room and the involved equipment.
The gradual start-up of the oil and gas production and the gas exports from the four fields started Tuesday morning. The fields are expected to be back on full stream in a few days.
Production at Brage, Oseberg C and Vesfrikk, which transports oil through the Oseberg field center, resumed on June 16 and has not been affected by the repairs.
