Abstract
Some implementations include a method for controlling a computer system configured to detect scaling and/or plugging of an electric submersible pump (ESP) deployed in a wellbore. The method may include determining, based on a measurement of pressure in the wellbore, a required total dynamic head (RTDH) for the ESP while the ESP is operating in the wellbore. The method also may include determining, based on information from one or more sensors in the ESP, a produced total dynamic head (PTDH) for the ESP while the ESP is operating in the wellbore. The method also may include detecting scaling status or plugging status of the ESP based on the RTDH and the PTDH.
