The Late-Life Well Strategy focuses on optimizing the management of aging oil and gas wells through three approaches: Integrity, which emphasizes maintaining the safety and operational reliability of existing wells; Intervention, which involves actively repairing or enhancing well performance; and Decommissioning, which entails safely plugging and abandoning wells that are no longer productive or viable. This strategic framework aims to balance economic efficiency with environmental responsibility as wells age.

In wells that have experienced excessive wear on the well structure and casing, there is significant uncertainty that current numerical methods can address. It is not always technically and economically feasible to remove a production string solely to assess the remaining thickness of the production casing or to hire a rig that has less impact on the wellhead system. This section describes techniques and alternatives to provide information and enable the extension of the well's life through a workover.
