A method serves for operating an electronically controlled pump assembly (1), with which setting parameters of the pump (2) can be adjusted in an electronic control (6), for adaptation to the hydraulic demands of the location installation situation (4, 5). Operating data is registered during the operation of the pump assembly (1). After a predefined time and on the basis of the registered operating data, it is examined as to whether the pump assembly (1) has been set vis-à-vis the factory settings. If this is not the case a signal (11) is issued in order to point out the necessary setting.

One or more sensors are mounted on a collar proximate to a motor shaft of a motor. The motor is associated with an electric submersible pump (ESP) located in a wellbore of a geological formation. The one or more sensors sense one or more identifiers located on the motor shaft of the motor. One or more of a rotation direction and rotation speed of the motor shaft is determined based on the sensing of the one or more identifiers. The motor is powered to pump fluid from a reservoir in the geological formation to a surface of the geological formation based on the one or more of the rotation direction and rotation speed of the motor shaft.

Systems and methods of restarting a downhole pump for pumping downhole fluid and located in a wellbore that include determining a pump reverse rotational frequency of a downhole pump caused by downhole fluid flowing in a downhole direction using a phase locked loop. A pump motor is driven at a motor reverse rotational frequency matching the pump reverse rotational frequency. The pump motor is then driven to accelerate the pump reverse rotational frequency and thereby pump the downhole fluid in an uphole direction. The pump motor is then driven to decrease the pump reverse rotational frequency while continuing to pump the downhole fluid in the uphole direction. The pump motor is then driven to change the rotation of the downhole pump to a forward rotation at a pump forward rotational frequency to pump the downhole fluid in the uphole direction.
