Remote, Real-Time Surveillance and Control Phoenix MultiSensor monitoring system motor temperature protection prevented ESP failure
2 PagesChallenge Phoenix* MultiSensor* monitoring systems were installed with REDA* electrical submersible pump (ESP) systems in 18 wells in the Wafra field for Petroleum Development Oman. On Well 9 in March 2003, unknown to the operator, an ESP was running against a closed valve and the motor temperature increased because there was no cooling flow. Solution The motor oil temperature was one parameter used as fail-safe protection against adverse operation conditions for the ESP . Threshold operating limits were preprogrammed in the motor controller. Therefore, the ESP was automatically shut down at 120 degC motor temperature, preventing a failure. Results The shutdown point protected the ESP from exposure to excessive temperature. The intelligent con- trols minimized ESP shutdowns, prolonging
