PMM-PCP systems offer improved operational performance and efficiency in crooked, deviated, horizontal wellbores
Borets Company, the leader in electric submersible pumping (ESP) systems with over 60 years artificial lift expertise, has been designing, manufacturing and servicing PMM driven submersible progressive cavity pumping (PCP) systems for more than 10 years. In this time Borets has installed over 1,500 systems worldwide.
PMM-PCP systems offer the improved operational performance and efficiency vs. other alternatives in wells with crooked wellbores, highly deviated sections or when operation is required in the horizontal. The system allows all the benefits of Progressing Cavity Pumps (PCP) without the safety and abrasion risks associated with a steel rod string to surface. The system is ideal for PCP systems where it is desirable to minimize the surface footprint of the well for environmental impact reasons.
The system has a proven ability to reduce the number of costly workovers associated with rod or tubing wear. Specific examples save 3- 5 pulls in a system life span saving customers thousands of well costs. Imagine operating PCP’s with no rod or tubing pulls.
The PMM-PCP opens up the range in which PCP can be applied. This allows operators to take advantage of the efficiency and solids handling ability of the PCP in wells where this technology was not an option due to well bore geometry. In these challenging conditions PMM-PCP can be the artificial lift of choice to improve economics in project that prove to be difficult to produce economically.

PMM-pcp System
INNOVATIVE TECHNOLOGIES. RELIABLE SOLUTIONS.
Submersible PCP systems are considered where traditional rod driven systems are limited by depth or where deviated or crooked wells have caused premature rod/tubing wear as submersible PCP systems have no rods.
However, the conventional Electrical Submersible PCP systems known commonly as an ESPCP comprises a conventional ESP Induction Motor coupled to a gear reducer, allowing the PCP to operate between 100-500 RPM.
The Borets PMM-PCP system has a very similar configuration to that of the ESPCP, however, the major difference is there is no gear box in the system.
A major limitation of conventional ESPCP is that it requires running a gear box that proved to be the most unreliable and costly component in the system. In addition the gear box adds length to the down hole assembly, making it difficult to place the unit in an acceptable landing area in deviated wells.
The standard induction motors used with the ESPCP system also have a lower electrical efficiency when compared to the PMM.
With the introduction of a 10 pole
Permanent Magnet Motor, which has specifically been designed to operate at PCP pump speeds between 350-750 RPM, it allows a submersible PCP system to operate with no need for a gear box. The overall length of the system is reduced. Furthermore, the PMM has a higher electrical efficiency when compared to that of a conventional ESP induction motor.
Permanent Magnet Motors utilize powerful rare earth magnets embedded in the rotor, this allows the rotor to rotate at the same speed as the magnetic field produced by the stator making it a synchronous motor and eliminating slip. Permanent Magnet Motors have a much higher power density allowing the motor to be shorter than a comparable IM The PMM’s also have the ability to output higher starting torque that of a comparable induction motor.
Application of PMM driven PCP is a viable artificial lift method, with the implementation of a new generation of Permanent Magnet Motor’s it is now possible to install systems with no gearbox. This has greatly improved both the reliability of the system and the economics of challenging wellbores.
With over 1,500 systems sold to date, a universal variable speed drive that can be used on both IM and PMM motors the PMM-PCP is a great solution to today’s challenges lifting low rate heavy oil challenges. It also offers new technologically means to produce deviated wells at lower rates than historically deemed feasible with ESP’s.
Each well and application is unique. We suggest getting with your local Borets representative and together collecting all of the well and fluids data needed to design a PMM-PCP system.
