Petroleum Safety Authority conducts Barents Sea South-East audit

Petroleum Safety Authority has completed an audit of Statoil's planning process and preparations for exploration drilling of well 7435/12-1 in Barents Sea South-East.

Barents Sea South-East is a new area for exploration drilling, without nearby wells from which to draw significant experience. Great distances and the Arctic location may entail particular area and location-specific challenges for the planning and execution of exploration drilling.

The purpose of the audit was to examine how Statoil, along with the drilling contractor and other parties involved, have conducted the planning process. This included gathering information, use of the relevant experience and risk assessments for preparing robust plans for exploration drilling in the new areas opened up in Barents Sea South-East, and well 7435/12-1 specifically.

No non-conformities were identified. However, improvement points were identified linked to risk reduction, decoupling from blowout preventers in the event of incidents, routines for testing the ice deflection system and monitoring and managing ice fragments.

Petroleum Safety Authority has asked Statoil to report on how the improvement points will be addressed by 21 August.
