Technical post-well investigation of planning and execution performance relating to plug and abandonment of a subsea exploration well were 28 rig days lost due to gas leak from the well.

What we did

We collected and analyzed data and conducted interviews to compare plans and execution performance versus requirements in the local regulations, Client’s Management system and the NORSOK D-010 Well Integrity standard.


The planned P&A design solution was compliant with requirements. The final well status was compliant with regulations, partially compliant with Client’s requirements and non-compliant with NORSOK D-010. Improvements to the Client’s Well Barrier Philosophy were suggested.
