PCP with topside and downhole motors

Progressive Cavity Pumps

The downhole PC pump is a positive displacement pump that consists of two parts:

  • Helical steel “rotor”
  • “Stator” comprised of a steel tubular housing with a bonded elastomeric sleeve formed with a multiple internal helix matched suitably to the rotor configuration

They are increasingly used for artificial lift, and have been adapted to a range of challenging lift situations (e.g., heavy oil, high sand production, gassy wells, directional or horizontal wells).

PCP systems have several unique design features and operating characteristics that favor their selection for many applications:

  • High overall system energy efficiency, typically in the 55 to 75% range.
  • Ability to produce high concentrations of sand or other produced solids.
  • Ability to tolerate high percentages of free gas.
  • No valves or reciprocating parts to clog, gas lock, or wear.
  • Good resistance to abrasion.
  • Low internal shear rates (limits fluid emulsification through agitation).
  • Relatively low power costs and continuous power demand (prime mover capacity fully utilized).
  • Relatively simple installation and operation.
  • Generally low maintenance.
  • Low profile surface equipment.
  • Low surface noise levels.
  • Available PCP specifications for top and downhole drives.

Novomet provides two types of PC pumps:

  • with top drive;
  • with downhole permanent magnet motor without a gearbox (with thrust chamber).
