(OTC 24138) Reliable High Power ESP Tubing Hanger Connector Systems for Deepwater Downhole Applications

摘要

Electrical Submersible Pumps (ESPs) play a major role when it comes to artificial lift in deepwater reservoirs. Reliability of subsea equipment is an indispensable requirement in deepwater applications due to the high cost of interventions. Tubing hanger connector systems can be a critical failure mode for the ESPs in a High Pressure and High Temperature (HP/HT) environments. Through use of reliability tools such as the Fault Tree analysis, Failure Mode Effect and Criticality Analysis (FMECA), and systems Reliability Block Diagrams (RBD) it was established that improving the reliability of the tubing hanger connector system has a direct impact on the un-intervened life of the ESP electrical system.
