Inactive Well Monitoring Program Design
The procedures discussed in this document are intended for operators use in designing their own inactive well programs. The primary concern in managing inactive wells is identifying changing wellbore conditions in a timely manner so action can be taken before fluid migration occurs. For example, if monitoring indicates the completion interval changes from a non-pressured formation to a pressured formation, the operator should reevaluate the well’s fluid migration potential and take action, as appropriate. The purpose of the program is to monitor pressures and to take appropriate action when unusual changes occur.
The guidelines and examples presented are not intended to cover ail wellbore conditions or pressured formation scenarios. It is assumed that operators will use these concepts to design specific programs to meet any special circumstances that may arise.
NOTE: When developing inactive well program, operators should consult applicable Federal, state, and local regulations, as well as consider lease and landowner obligations, to ensure their program meets all requirements.
