The ESPs' reliability is mainly expressed through run-life metrics such as Mean Time Between Failure (MTBF), where significant research has been made to develop methodologies to calculate and interpret run-life metrics and eventually improve designs and operational efficiency. Dominantly, the ESP run life depends on the design and operating conditions, and there are still significant challenges that these systems are experiencing, especially in harsh environmental conditions where extensive gas, solids, and water production can deteriorate pump run life.

Since ESPs can fail due to multiple reasons, failure analysis and identifying the failure's root cause are critical in improving future designs. In general, failure analysis can be divided into three types: detection, isolation, and prognosis. Failure detection is simply recognizing that the failure occurred without acting or knowing the root cause. Failure isolation identifies the root cause of failure, while prognosis refers to predicting the time the equipment will fail.
