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.
