Anglo-Dutch supermajor Shell has been hit with a safety order from the Norwegian authorities following an investigation into a well incident on the Draugen platform in December last year.

The Petroleum Safety Authority said today its investigation of the incident identified several serious breaches of the regulations.
The non-conformities are related to inadequate management, inadequate risk assessment, inadequate well barriers, inadequate well barrier sketches, inadequate well control, and inadequate daily reporting of drilling and well activities, said the PSA.
The incident occurred during a wireline operation to replace a gas lift valve in well 6407/9-A-01. The operation resulted in the subsurface safety valve becoming stuck in the Xmas tree, blocking the upper mast valve, and leaving only one barrier against a potential leak.
