PCP

Workover & Intervention

A Progressing Cavity Pump (PCP) is a type of positive displacement pump used for artificial lift. It consists of a single helical metal rotor rotating inside a double helical elastomeric stator. As the rotor turns, cavities containing fluid progress upward, lifting the oil.

PCPs are exceptionally good at handling viscous (heavy) oil and fluids with high sand content, making them popular in heavy oil fields like those in Canada using CHOPS (Cold Heavy Oil Production with Sand). They are simpler and often cheaper than ESPs but are limited by the temperature and chemical resistance of the elastomer stator.
