A method and apparatus for operating a pumping system includes the following: determining a motor operating parameter of a motor configured to drive a pump in a well; determining a pump operating parameter of the pump based on the motor operating parameter; operating the pump in a first mode to determine pump characteristics at a desired fluid level; generating first mode output data based on operation of the pump in the first mode; operating the pump in a second mode based on the first mode output data; determining an estimated fluid level in the well based on the motor operating parameter, the pump operating parameter and the first mode output data; and adjusting the pump speed based on the estimated fluid level in order to maintain a desired fluid level. |
