System and method for measuring discharge parameters relating to an electric submersible pump

A method for measuring and transmitting parameters relating to an electric submersible pump (ESP) system, comprising:

• providing an ESP monitoring system, wherein the ESP monitoring system comprises a base monitoring unit and a discharge monitoring unit that are communicably coupled via a ground path, and wherein the discharge monitoring unit is hydraulically coupled to a pump discharge of a pump of the ESP system and the base monitoring unit is electrically connected to a motor of the ESP system;
• measuring at least one base parameter relating to the motor and/or a pump intake of the pump using the base monitoring unit;
• measuring at least one discharge parameter relating to the pump discharge using the discharge monitoring unit;
• transmitting data corresponding to the at least one discharge parameter from the discharge monitoring unit to the base monitoring unit via a ground path;
• combining, via the base monitoring unit, the data corresponding to the at least one discharge parameter and data corresponding to the at least one base parameter;
• and
• transmitting the combined data from the base monitoring unit to an ESP surface unit via an ESP power cable.

An electric submersible pump (ESP) system, comprising:

• a shaft;
• a motor configured to rotate the shaft in response to receiving power via an ESP power cable;
• a pump that is operatively coupled to the shaft, wherein the pump comprises a pump intake and a pump discharge;
• and
• an ESP monitoring system, comprising:
• a base monitoring unit;
• and
• a discharge monitoring unit that is communicably coupled to the base monitoring unit via a ground path;
• wherein the discharge monitoring unit is hydraulically coupled to the pump discharge and is configured to:
• measure at least one discharge parameter relating to the pump discharge;
• and
• transmit data corresponding to the at least one discharge parameter to the base monitoring unit via the ground path;
• and
• wherein the base monitoring unit is electrically connected to the motor and is configured to:
• measure at least one base parameter relating to the motor and/or the pump intake;
• receive the transmitted data corresponding to the at least one discharge parameter from the discharge monitoring unit;
• combine the data corresponding to the at least one discharge parameter and data corresponding to the at least one base parameter;
• and
• transmit the combined data to an ESP surface unit via the ESP power cable.
