Statoil confirmed it had successfully resumed partial production at its Snorre B platform.
The North Sea platform was shut down on Monday after the firm identified a shift under a drilling template and then later a leak.
A spokesperson today said: “Production from one template will remain shut in until further examinations have been concluded. The other production from Snorre B has now resumed.”
The Snorre field is one Norway’s biggest oil producers, averaging 88,000 barrels of oil per day.
A quarter of the platform’s staff were evacuated after the alarm was raised.
The area is under continuous ROV surveillance.
Monday’s shut down was the second time in three days Statoil was forced to stop oil production on the platform, which is located in the northern part of the North Sea.
On Saturday, the firm shut production shortly after a subsea robot identified a pit under the drilling template.
