Advanced Well Integrity Management

Introduction

The Well Integrity Forum (WIF) was established in 2007 and one of the main issues that were initially brought up for review was well-integrity training. WIF members acknowledge a need for well-integrity training of key personnel working with well integrity offshore and onshore.

This training is designed to provide the participants with knowledge and deeply investigate the faultier and risk of well integrity. The participants have an excellent chance to share ideas and to correct the concept of well integrity management. The training seminar will discuss the proper approach to decision-making to provide certainty within the organization.

The knowledge and skills to make critical decision throughout well life cycle is vital, not only for WIM purpose but as well as for economic value. The training seminar will focus on the Well Integrity management systems and interfaces with other teams in the organization. Integrity barriers are defined, Well Failure model and how to establish one is discussed, as well how to create an efficient well integrity organization.

The training will deepen your knowledge of well integrity management, and develop the skills for designing, operating, and maintaining well equipment with the ultimate objective of ensuring a permanent, safe containment of all wellbore fluids.

This training will feature:

• The Concept of Well Integrity
• Awareness of Regional Standards and Regulations
• Different Stages of Well Operations from Design and Construction, to Production Impact Well Integrity
• Risks associated with Different Types of Well Integrity Issues
• Different Techniques to Reduce / Mitigate Risks
• Procedures, Roles and Responsibilities of Personnel involved in the Well Lifecycle towards Well Integrity
• The Focus on Key Areas of Well Integrity Assurance
• The Production Supervisor’s duties with regard to Well Integrity

Objectives

This training aims to:

• Improve the delegates’ appreciation of the well design and annulus construction; i.e. the well as a “pressure vessel”
• Provide knowledge & understanding of the guidelines and standards that when observed and implemented effectively will ensure well integrity
• Establish an increased awareness of well integrity issues and how they are controlled / managed and by whom
• Provide knowledge on how to maintain equipment for safe and effective operation

Training Methodology

This training seminar will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented. The daily workshops will be highly interactive and participative.

Organisational Impact

The organization will gain, in sending their employees to attend this particular training seminar, the following:

• Reduction in the cost of the well in addition avoiding the environmental pollutions
• Extending the well life including all the affecting items in well design
• Ensuring the well integrity, avoiding all risks and solve the problem in a logic and simple ways

Personal Impact

• Obtain integrating knowledge in well integrity management
• Hone their knowledge and get the self-confidence for well design in the proper methods
• Get the latest technology in well inspection, the way to control any problem and the procedures for monitoring
• Solving and avoiding the problems which impact on the cost reduction, and well integrity

Who Should Attend?

This training seminar is suitable to a wide range of professionals but will greatly benefit:

• Affiliate Technical Directors
• Asset Manager
• Petroleum Engineers
• Production Technologists
• Production Personnel (Production Operators, Maintenance Supervisors)
