Audit of StatoilHydro – well control competence

Audit: On 23 and 24 April 2009 the Petroleum Safety Authority Norway (PSA) carried out an audit of StatoilHydro (SH) at Forus. The audit targeted the company’s systems, routines and follow-up of well control competence for drilling and well operations. We did not identify any non-conformities in relation to regulatory requirements.


Background for the audit
Prevention of major accidents is a priority area for the PSA and in Storting White Paper No. 12 (2005-2006).

The industry has revised OLF/NR guidelines No. 024 for the 2007 to 2009 period. We are conducting auditing activities focused on well control to follow up how the industry is preventing major accidents. Similar auditing of drilling contractors and operating companies were carried out during the 2003 to 2007 period. 

The PSA carried out a well control audit with Statoil on Veslefrikk in November 2004, and with Hydro on Oseberg Sør in April 2005. The company’s measures following these audits were followed up as part of this audit activity. 

Reports submitted to “Risk level in the Petroleum Activity” (RNNP) show that SH has had several well control incidents at its facilities.

Purpose of the audit
The purpose of the audit was to ensure that the company’s management system for safeguarding health, safety and environment in connection with well control training and exercises is functioning.

Result of the audit
The company’s systems, routines and follow-up of tasks involving well control competence in drilling and well operations were reviewed and assessed in relation to current regulatory requirements.

We did not identify any non-conformities in relation to the regulatory requirements.

During the audit, we identified areas of improvement connected to

  • Simulator training and practical training
  • Follow-up of well control exercises and training conducted by the onshore organisation
  • Overview of well control requirements in governing documents
  • Coordination and group competence
  • Well control training specific to the activity, location and facility
  • Follow-up of training and educational institutions
  • Transfer of well control experience
