Audit of new work processes within drilling and well activities using ICT - Statoil

From 24 - 25 January 2012, the Petroleum Safety Authority Norway (PSA) carried out an audit of Statoil’s follow-up of new work processes within drilling and well activities using information and communication technology (ICT).

The PSA must have an overview of the HSE challenges in the petroleum activity and contribute to create a unified and comprehensive picture of risk factors in the industry as a basis for implementing preventive measures. Managing major accident risk requires understanding of the complex interaction between people, technology and organisations. Introducing new information and communication technology along with associated new work processes creates challenges that are common for many players in the petroleum activities. We started the mentioned audit activity to contribute to the development of robust work processes and to improve safety.

The objective of the audit was to investigate how Statoil ensures the work processes within drilling and well activities, and the decisions connected to these, as well as how the company maintains health, safety and the environment (HSE) requirements.

The following topics were reported and reviewed during the audit activity:

− Organisation of drilling and well activities for the Snorre field

  • Use of new information and communications technology
  • Review of concrete work processes for a drilling operation, including interaction between onshore and offshore
  • The role of the onshore operations centre – including during hazard and accident situations
  • Integration and involvement of technical environments and contractors
  • Facilitation for interaction

− Change management in connection with a drilling operation, including interaction between onshore and offshore and all involved parties

  • Criteria for starting a formal change process
  • Decision basis
  • Highlighting change in risk
  • Change communication and traceability

− Human factors when designing the work processes (interaction onshore and offshore.

  • Analyses carried out when designing the work processes as regards staffing, expertise and capacity
  • Maintaining user-friendliness of real-time-based systems for visualisation, alarm handling, etc.
  • Measures for establishing and maintaining professional trust between onshore and offshore, and between operators and contractors

− Acquisition, processing and use of real-time data

  • Responsibility/interface in connection with acquisition of real-time data
  • Ownership and maintenance of sensors

− Use of simulation and visualisation to support decisions

− ICT security

  • Roles and responsibilities to maintain ICT safety in the interface between onshore and offshore
  • Mapping and risk assessments of ICT-based systems that are relevant for drilling
  • ICT-based drilling systems against requirements
  • Challenges within ICT safety

Three improvement items were identified during the audit activity in connection with, respectively

− Responsibility and management related to ICT security
− Updating technical operating documents
− Interfaces in work process description
