Reda Thermal
Power-efficient geothermal electric submersible pump
Our pump is a reliable, high-flow-rate pump for high-enthalpy geothermal wells.
For oil and gas, mine dewatering, and geothermal Reda ESP pumps
The permanent magnet motor (PMM) is a three-phase, oil-filled motor with permanent magnets mounted in the rotor. Its unique design enables superior performance, improved efficiency, and higher power factor, resulting in reduced power consumption when compared with standard induction motors.
Lowers electricity consumption by a minimum of 10%†
Reduces greenhouse gas emissions by up to 143 metric tons of CO2e per well per year†,‡
Benefits multiple industries, including geothermal energy production, where the pump's electricity consumption is considered a parasitic load
† Performance improvement is based on a 4.61-in [117-mm], 322-hp motor configuration compared with previous-generation induction motor technology. Calculations are
based on a run life of 365 days with 100% uptime and take into consideration efficiency losses of the power cable, variable frequency or variable speed ESP drive, and
transformer.
‡ The conversion from electricity to CO2 is based on the IEA Emission Factors 2019 reference of 485.30 g of CO2/kW.h.
PMMs for ESPs are used with Reda ESP pumps in multiple industries, including oil and gas, mining (for dewatering), and geothermal energy production.
An alternative technology in electrical downhole drives, PMMs are assembled and run in the same way as conventional ESP motors and are suited for most applications.

Read premium contentAssessing the power efficiency of ESPs is a practical first step to reducing energy consumption and the resulting emissions during operation. Pumps and motors are the components with the largest impact on energy consumed.
Our PMMs are filled in a controlled environment with high-temperature synthetic oil to provide dielectric strength, bearing lubrication, and thermal conductivity. The ESP flange connection facilitates reliable motor and protector connections while ensuring a leak-tight seal. MaxLok™ ESP quick-plug motor lead extension (MLE) simplifies making up the pothead to the motor with a plug-in connection that eliminates taping of pothead terminals at the wellsite.
The gauge-ready base is compatible with any Phoenix artificial lift downhole monitoring system sensor for real-time monitoring of ESP and reservoir properties. A temperature sensor connected directly to the motor winding enables monitoring motor-winding temperature in real time through all stages of operation.
SLB has implemented operational standard work instructions globally to enhance the safety of everyone involved in installing, operating, and removing PMMs. Training for your personnel is available on request at our assembly, repair, and test (ART) centers.
PMMs are synchronous electric machines—the rotor rotates at the same speed as the magnetic field in the stator. This synchronous operation reduces losses in the core, resulting in less heating and an expanded operating envelope for the ESP.
For optimal operation, PMMs require a variable speed drive (VSD) with special control algorithms to time the switching of the output transistors and control the current in the motor windings. The incremental cost of upgrading to a VSD is quickly recovered.
ESP PMMs are part of our Footprint Reduction portfolio that sustainably drive high performance. Learn about our collaborative approach and full field development solutions that drive high performance, while reducing environmental impact throughout the life of your asset.
