The incident occurred in connection with a wireline operation on Draugen in Well A1 to replace a downhole safety valve. The safety valve got stuck in the christmas tree, preventing operation of the upper and lower master valve.
The PSA will start its investigation on Tuesday with the objective of clarifying the course of events and identifying triggering and underlying causes.
The investigation will result in a report that will be published on the PSA’s website.
The operator on Draugen is A/S Norske Shell.
