The understanding of well integrity and fatigue challenges are in relative early stages. The deeper we “dive” into these issues the more challenges are

becoming apparent.

Operations and materials are two important issues as well as better instrumentation to gain more knowledge.

An understanding of the interdependence of the parts in the overall system and operations is vital to a safe management of these issues.
