COURSE OVERVIEW:

 Well Integrity of Cased Hole: Diagnostics and Remediation is an advanced technical course focused on the identification and repair of subsurface barrier failures. Once a well is cased and cemented, diagnosing leaks or structural degradation requires sophisticated tools and interpretive expertise. This course provides participants with the skills to analyze casing and tubing failures, identify the precise location of leaks, and design engineering solutions to restore integrity.

The scope of this training includes a deep dive into diagnostic logging technologies, such as multi-finger calipers, ultrasonic thickness tools, and electromagnetic defectoscopy. Participants will learn how to differentiate between corrosion, erosion, and mechanical damage using advanced data sets. The curriculum emphasizes the "Decision Tree" for remediation, helping engineers choose between chemical treatments, mechanical patches, or full-scale workovers.

Coverage also focuses on the execution of remediation techniques. Attendees will explore the mechanics of "Squeeze Cementing" for zonal isolation repair, the installation of expandable liners, and the use of chemical sealants to cure small-volume leaks. By mastering the diagnostic-to-remediation workflow, participants will be able to extend the productive life of damaged wells, minimize environmental risks, and avoid the high costs of premature abandonment.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Interpret advanced diagnostic logs for casing and tubing inspection.
• Identify the root cause of casing deformation and collapse.
• Utilize noise and temperature surveys to pinpoint micro-annular leaks.
• Distinguish between active corrosion and historical metal loss.
• Design a remediation plan for a failed primary cement bond.
• Evaluate the technical and economic feasibility of casing patches and liners.
• Perform volume and pressure calculations for squeeze cementing operations.
• Utilize chemical resins and sealants for precision leak remediation.
• Assess the integrity of "wellhead-to-wellbore" connections.
• Select appropriate repair materials for high-pressure and corrosive service.
• Manage the risks of remedial workovers in aging wellbores.
• Verify the success of remediation through post-job integrity testing.
• Document the "As-Repaired" barrier status for regulatory compliance.

TARGET AUDIENCE:

Senior Well Integrity Engineers, Production Engineers, Workover Superintendents, and Technical Specialists involved in asset remediation.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
