Abstract

A method to determine downhole fluid flow rate of a wellbore is disclosed. The method includes generating, using sensors of a discharge sub and a suction sub coupled to an electrical submersible pump (ESP), monitoring data of the ESP that is suspended in the wellbore via a production tubing to facilitate well fluid flow to the Earth's surface through the production tubing, wirelessly transmitting, using wireless transmitters of the discharge sub and the suction sub, the monitoring data to a monitoring sub coupled to an electrical motor of the ESP, transmitting, by the monitoring sub to a downhole flow rate analyzer at the Earth's surface, monitoring data wirelessly received from the discharge sub and the suction sub, and determining, by the downhole flow rate analyzer, the downhole flow rate of the well fluid by analyzing the monitoring data.
