This course is designed to provide participants with up-to-date overview of well integrity management. It covers the well integrity for the operational phase and well integrity life cycle; the barrier standards and applications, barrier verification and subsequent monitoring; the various examples of well integrity management systems; the completion design for sustained well integrity and the function of each component. Further, the course will also discuss the component (barrier) fails including the reliability and operability concerns; the stress and loads on completion strings and manual calculation; the external and internal influences like corrosion on the well integrity envelope and how to design for them; the change of well operating envelope; the well failure models and risk assessments, well integrity verification, confirmation of barrier envelope and the various types of well integrity testing; and the issues associated with sustained casing pressure and/or MAASP excursions. During this interactive course, participants will learn to conduct the well/field investigations and changes to well operating envelope; repair and reinstate well barrier envelope; employ rig interventions, planning for workovers, remediations on wells with well integrity issues including multiple barrier failures; recognize the rigless remediation options covering sealants, straddles, insert SSSV’s; apply management of change, extension of a well life and well suspension (temporary or permanent); and identify the criteria for extending or changing a well status as well as well abandonment, current technologies and methods.
