Technical Agenda

Tuesday, 23 April, 0900-1030

Session I: Lifetime Extension and Suspension

Session Managers: Martin Mosley and Ian Taylor

The first session is intended to challenge the perspectives of attendees. Problems associated with the ageing and degradation of wells provides opportunities to develop a broader understanding of well integrity management.

Part 1—Well life management and understanding the degradation of wells

• The well life cycle and the concept of integrity management from design through construction, operation and abandonment.
• UK key programme 4, asset ageing and life extension—the concept and implication for full life management of wells.
• Degradation and failure of well components, using data to predict failures and the need for equipment replacement. This will include the age-related reassessment and potential down-rating of the structure and containment of wells.

1100–1230

Part 2—The degradation and operational ‘death’ of mature wells can challenge normal well integrity decisions

• Balancing value, cost and risk and maintaining fitness for purpose.
• Asset commitment to wells in terminal decline—integrity management of dead wells including consideration of plugging, suspension and abandonment of individual wells prior to field abandonment.
• Examples of difficult decisions will be presented to stimulate a broader consideration of barriers and risks in the later sessions of the workshop.

1330–1700

Session II: Well Barrier Assessment Best Practices I

Session Managers: Alex Crabtree and MJ Loveland

Two half-day sessions will be dedicated to well barrier assessment best practices. In each session, well barrier topics will be reviewed in detail via presentations, facilitated open forums, and/or table work group discussion formats. Delegate input and participation will be encouraged.

Well Barrier Assessment Best Practices I will review the current industry conformance criteria, including:

• Industry barrier evaluation techniques
• Testing and acceptance criteria
• Annulus monitoring

Wednesday, 24 April, 0900-1230

Session III: Well Barrier Assessment Best Practices II

Session Managers: Lars Tore Haug and Paul Hopmans

Well Barrier Assessment Best Practices II will focus on trouble shooting and repair techniques with the following topics:

• Available diagnostics and testing tools
• Barrier failure case studies
• Barrier repair options

1330-1700

Session IV: Legislation/Regulation

Session Managers: Nigel Snow and Phill Webb

In this session we will discuss the various different approaches to legislation around the globe focusing on an interactive debate on the merits of various global regulation models—should there be a universal standard? There will also be an update on the new ISO/OGP Well Integrity Standard.

Thursday, 25 April, 0900-1230

Session V: Risk Management

Session Managers: Kjell Corneliussen and Simon Sparke

In recent years, many oil and gas companies have recognised the need for improved management of well integrity issues.

Effective well risk management offers significant benefits, such as:

• Improved safety through increased focus on well integrity
• Early detection of failures with a direct impact on well integrity
• Improved visibility of well integrity inside and outside the company, by allowing clear key performance indicators (KPIs) to be developed and tracked
• Efficiency in field operations

Introduction of efficient risk management needs involvement by the entire organisation working with the different aspects of well operations. It also requires development and revision of policies, guidelines, standards and procedures.

This session will give examples of well integrity management from different operators. Some will present lessons learned from systems that have been implemented and are in use, while others will present the status and strategy for implementing new/revised management systems.
