The ESP Downhole Monitoring System is a real-time multi-parameter sensor system designed to provide continuous monitoring of essential downhole parameters in an Electrical Submersible Pump (ESP) system. It consists of four primary components:
- Downhole Sensor – Measures pressure, temperature, vibration, and other critical parameters.
- Flow Nipple – Facilitates fluid flow and sensor integration.
- Underground Control Box – Processes and transmits sensor data to the surface.
- Underground High-Pressure Box – Protects electronic components from extreme well conditions.
The sensor unit utilizes motor star points, power cables, and the earth to create a circuit, enabling the transmission of real-time wellbore data to the surface. The collected data integrates seamlessly with the intelligent ESP management system, allowing for remote monitoring, automated adjustments, and predictive maintenance to optimize ESP operation and extend equipment lifespan.
Additionally, the system supports up to 24 optional monitoring parameters, depending on the additional equipment in use, such as:
- Pump intake pressure & temperature
- Motor oil & winding temperature
- Motor vibrations & current leakage
- Pump discharge pressure
- Anti-scaling electromagnetic unit
- Motor RPM measuring unit
