Through this audit we examined how Statoil is able to document that all the challenges have been identified and risk-assessed and that necessary measures have been established for performing permanent plugging of the wells in a safe manner.

The audit also looked at how Statoil ensures that established barriers in the wells comply with the regulations in respect of positioning, length and soundness.


Two non-conformities were identified in connection with:

  • Decision support
  • Non-conformity handling

In addition, an improvement point was identified in connection with the overview of historical data.

Statoil has been given a deadline of 22 February 2018 to report on how the non-conformities and improvement point will be addressed.
