Abstract
A system for monitoring a condition of a downhole electrical submersible pump (ESP) assembly is disclosed. The system includes: a downhole assembly configured to be disposed in a wellbore in an earth formation; the ESP assembly connected to the downhole assembly and including a motor and a pump, the ESP assembly in electrical communication with a surface electrical source via a conductor; a power gauge unit configured to measure the electrical power supplied to the ESP assembly; and a processor configured to receive data from the power gauge unit and calculate a flowrate of the ESP assembly based on at least the electrical power supplied to the ESP assembly. Also disclosed is a method of monitoring a condition of a downhole ESP assembly.
