This training course 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
• 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 of how to maintain equipment for safe and effective operation

By the end of this course, delegates will be able to:

• Identify well problems from available well data
• Understand guidelines, procedures and standards
• Appreciate design intent of completion equipment and their impact on well integrity
• Be conversant in the care and operation of surface intervention equipment

Fundamentals of Well Integrity and Detection of Problems

• Definition of the various components of the well and showing the integrity barriers
• Designing Integrity in Wells-Completion Design-Life expectancy
• Influences on Well Integrity and why it needs managing
• Preventive maintenance reduces operating cost and optimizes production
• Maintenance Processes and Differences
• External well integrity maintenance
• Internal well integrity maintenance
• Ways of losing well integrity.

Technology & Tools for Internal Well Integrity Diagnostic & Monitoring

• PLT Logging Techniques
• Securing internal integrity, reservoir reconciliation, leak detection etc.
• Establishes tubing base line wall thickness and corrosion over life cycle of the well
• Non-intervention less investigations like Pressure testing
• Detects leaks
• Production profile

How to Prevent Catastrophic Failure of a Well caused   by External and Internal Corrosion

• Risk to the completion string from internal sources
• Barrier understanding
• Show different types of wells
• Monitor for and understand mechanical integrity problems preventing potential production rates
• Sand removal
• Impact of Paraffin’s and Asphltien on well integrity
• How to treat these problems in a proper ways?
• How to execute scale removal
• Cement squeeze for water and gas shut off.

Consequences of Loss of Integrity of One Well to its Surrounding

• Increasing amount of Underground blowouts
• Abandonment: Temporary and permanent

Well Integrity & Barrier Philosophy and How Testing is Done

• Well Failure Model - How to arrive at the document
• Group Exercise
• Referring to the barriers discussed above, make a plan to test and verify the barriers
• Leak rate determination calculations
• Risk Based Well Integrity Management and Testing
• The management of Barrier testing
• Discuss testing methods of the barriers in the well
• Failure Mode and Effects Analyses Diagram (real case document)
• Show barriers, function and its severity in case of failure
• Discuss testing and managing the data
• Provide systems and procedures, which ensure that the integrity of the well is assured
• Ensure that the well is maintained with reference to appropriate procedures and specifications
• Ensure that the risks of operating the well are as low as reasonably practicable
• Basis for the development of asset-specific well maintenance and integrity standards, policies, procedures and performance targets

Optimize Well Completion to Optimize Well Integrity during the Lifespan of the Wells

• How to build an organization with sufficient Well Integrity competence and capability
• Understanding of lowest unit cost, as opposed to cheapest
• Competent staff

Example of Well Head Maintenance Manual

• Well Failure Model
• Failure Modes and Effect Analyses
• Risk Based Well Maintenance
• Well Hand Over Form
• Well Head Check Sheet

CDGA attendance certificate will be issued to all attendees completing minimum of 80% of the total course duration.
