KUDU Rodless PCP

Submersible electrical motor and PCP system

Eliminate the root cause of PCP failure

Sucker rod and tubing wear cause 30%–50% of progressing cavity pump (PCP) failures. The severity of wear depends on factors such as dogleg severity (DLS), water cut, sand cut, and wellbore inclination.

Eliminate rod failure with the KUDU Rodless submersible electrical motor and PCP system, which enables pump installation in a high-dogleg severity (DLS) or horizontal section of the well and significantly increases uptime. With no rodstring, torque reduces 20% to 60%, efficiency and safety increases, and power consumption decreases.

Real-time monitoring

Uses telemetry to prevent pumpoff conditions and monitor performance

Multisensor gauge

Measures intake pressure, intake and motor winding temperature, and vibration

Compatibility

Works with ESP completion technology

Enable production over a wide operating range

The system features a low-speed downhole permanent magnet motor (PMM) drive and a PCP that work together without being limited by deviation profile. Adopting a low-speed PMM enables the KUDU Rodless PCP system to provide constant torque throughout its operating speed range from 50 to 750 rpm. Such system flexibility enables easy adjustment to a broad range of well production rates without replacing the pump.

The PMM also improves efficiency with low power loss in the rotor, increases power density with a shorter motor, and enhances dynamic performance with a variable frequency drive (VFD) specifically designed for PMMs.

Real-time downhole monitoring system

The system uses downhole telemetry to prevent pumpoff conditions, monitor equipment performance, and optimize well production. A multisensor downhole gauge package measures intake pressure, intake temperature, motor winding temperature, vibration, and pump discharge pressure (optional).

Downhole signals are interpreted by a data acquisition system on the surface and then sent to the VFD for monitoring, control, and recording.
