Audit of HSE management of wireline operations

During the period 22-23 March 2006, we conducted an audit of HSE management in Schlumberger North Sea Geomarket (Schlumberger). The audit targeted the company's wireline activities on the Norwegian shelf, primarily as regards their wireline contract with Norsk Hydro. Subsequent to the audit, it is our impression that Schlumberger has established a well arranged management system for following up health, safety and environment.


In our audit, emphasis was placed on management elements rather than details in the respective technical areas.

The audit was conducted by means of meetings and interviews with personnel in Bergen, as well as verification of specific documents in the management system.

Background for the audit

The audit activity is part of the Petroleum Safety Authority Norway's efforts vis-à-vis contractors and in furtherance of our goal of more uniform follow-up of all players in the petroleum activities.

About 60% of the people who are employed offshore work for contracting companies. The percentage varies from facility to facility and depends on which types of activities are carried out.

Contractor employees are often involved in actually executing various work tasks and are thus closely involved with the physical risks, while at the same time, they work under the systems and framework conditions that apply for the operating company, drilling contractor or primary company.

This is the second audit directly targeting a well service company as the obligated party.

Purpose of the audit

The purpose of the audit was to obtain an overview of Schlumberger's management system for safeguarding health, working environment and safety in connection with wireline activities on the shelf, as well as to verify compliance with HSE requirements in all phases/parts of the management loop. Therefore, the audit focused on management elements rather than details in the respective technical areas.

Another objective was to illuminate aspects of the interfaces between well service company, other contractors and the operating company.

Result of the audit

Our impression is that Schlumberger has established a well arranged management system for following up health, environment and safety, and that employees both on land and offshore have good access to this system.

We also have a positive impression of Schlumberger's "InTouchSupport.com" system, which handles sharing of experience within the company as well as technical support from technical support teams. Furthermore, it is our impression that the company has facilitated the training of "trainee" wireline engineers, wireline operators and apprentices.

During the audit, we identified some nonconformities and elements with a potential for improvement in the following areas:

  • Maintenance management

  • System for handling nonconformities

  • HSE targets and activity plans

  • Competence/ training
