摘要： A system can include a housing that defines an interior space; a shaft disposed at least in part in the interior space of the housing where the shaft includes a longitudinal axis, a curved surface and an end surface; a submersible electric motor operatively coupled to the shaft where the submersible electric motor includes a cable connector; two proximity sensors where each of the proximity sensors includes a sensor aperture disposed in the interior space of the housing; and circuitry operatively coupled to the proximity sensors that determines position values of the shaft with respect to time based at least in part on output of the proximity sensors.

摘要： 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.
