Audit of Statoil and Songa Offshore – Troll field

We have carried out an audit of Statoil Petroleum (Statoil), Songa Offshore (Songa) and relevant drilling and well service contractors as concerns their planning and execution of drilling and well activities on the Troll field using Songa Endurance.

The objective of the audit was to verify that Statoil and Songa, and their contractors, are complying with the regulatory requirements for planning, risk assessment and execution of drilling and well operations.

In the audit, we emphasised how decision support, criteria and processes, including risk assessments and analyses, are established and implemented in order to safeguard well control and ensure robust operations.

Four non-conformities were identified in connection with:

  • Intersecting wellbores
  • Risk analyses
  • Capacity and competence in Statoil's Troll organisation
  • Well/fire service companies

In addition, two improvement points were identified in connection with:

  • Application of Management of Change (MoC)
  • Understanding of risk and responsibilities

Statoil and Songa have been given a deadline of 15 January 2018 to report on how the non-conformities and improvement points will be addressed.
