An electric submersible pump system can include a multiphase electric motor operatively coupled to a fluid pump; a multiphase power cable operatively coupled to the multiphase electric motor; and a controller that includes an input that receives measurements as to power supplied to the multiphase electric motor via the multiphase power cable and that processes the measurements to determine information germane to the operation of the electric submersible pump system.

ESP pump flow rate estimation and control

A method can include receiving sensor information from at least one sensor disposed in a downhole environment that includes an electric submersible pump operatively coupled to a power drive via a cable; receiving electrical information associated with transmission of power via the cable; and identifying a state of the electric submersible pump via an adaptive model of at least the cable and the electric submersible pump based at least in part on a portion of the sensor information and a portion of the electrical information.

Submersible electrical system assessment

A method for determining electrical condition of a wired drill pipe includes inducing an electromagnetic field in at least one joint of wired drill pipe. Voltages induced by electrical current flowing in at least one electrical conductor in the at least one wired drill pipe joint are detected. The electrical current is induced by the induced electromagnetic field. The electrical condition is determined from the detected voltages.
