Electro-Magnetic Submersible Pumps

Linear Electric Submersible PUMP 

DIVERGENT’s new permanent magnet motor technology duplicates conventional rod pump movement without rod strings or surface lifting equipment. All moving parts are contained within the submersible pump housing, eliminating rod and tubing wear, making the Linear Motor ideal for placement into horizontal wellbores.

The linear-motion motor and reciprocating pump are landed on the end of the production tubing, with the power cable banded to the tubing.

 

Features

  • Reduced footprint on surface
  • Lower operating cost
  • Adjustable stroke length and rate
  • Low noise
  • No oil leakage from stuffing box
  • Remote monitoring and adjustments

 

Applications

  • Vertical, Slant, and Horizontal Wells
  • Pump rates to 42 m3/day (265 bbls/day)
  • Landed depths to 2000 m (6500 feet)

 

How it works

The submersible reciprocating pump is driven by a linear synchronous permanent magnet motor, which generates thrust from a magnetic field and permanent magnet mover.

Current is supplied to the motor only when the mover is travelling, and shut off between strokes. The absence of current between strokes allows for monitoring data to be transmitted to surface to the controller.
