3.  First developed by Rene Moineau in the late
1920
 Also known as screw pumps or Moineau
pumps.
 The progressive cavity pump (PCP) is a
positive displacement pump, using an
eccentrically rotating single-helical rotor,
turning inside a stator.

4.  The rotor is usually constructed of a high-
strength steel rod.
 They have been adapted to a range of
challenging lift situations (e.g., heavy oil,
high sand production, and gassy wells,
directional or horizontal wells).

5.  High-viscosity oil wells
 High-sand-cut wells
 Low-productivity wells
 Gassy wells
 Directional- and horizontal-well applications

6.  Surface drive systems
 Auxiliary equipment

8.  Wellhead drive units
 Power transmission equipment
 Prime movers
 Electronic speed control (ESC) systems
 Rod string backspin control devices

10. Higher efficiency 55 to 70%.
Lower cost than others
Simple construction
Some types are retrievable with rods.

11.  Short operating life (2–5 years)
 Elastomers in stator swell in some well
fluids.
 Lose efficiency with depth.
 Rotating rods wear tubing; windup and
afterspin of rods increase with depth.

12.  PCP recovers heavy oil, it is very much
efficient & it must be used when you want to
recover for short time period.
