State-of-the-Art for High Temperature ESPs

摘要

Electric Submersible Pump (ESP) systems have pumped oil for almost a century. They have been used successfully world-wide because of their flexibility, ability to produce high flow rates and accepted reliability. However, today's demands in the oil industry require a leap forward in reliability as field conditions get harsher. One of the most challenging environments for ESPs is thermal recovery methods typically used in heavy oil production. In order to survive the inherent demanding conditions of the application, ESPs had to go through a steep technological improvement, rethinking architectures that had been established in the industry for decades.
