PSA has posted the Gullfaks B gas release report in English. Also posted is the report on a lifting incident at Njord A. The reports are comprehensive and timely.
The gas leak occurred during leak testing after maintenance work on a production well. The gas derived from a volume trapped between the downhole safety valve and the Xmas tree. It proved impossible to operate the emergency shutdown valves on the well. The leak lasted about an hour, with an initial rate of 1.3 kilograms of gas per second. The volume of gas released is estimated at about 800 kilograms.
No people were injured in the incident, but the leak created a serious position on the installation.
