Progressing Cavity Pumps

The Progressing Cavity Pump (PCP), invented by René Moineau, is

a great innovation for the whole industry, particularly in petroleum

production. Since 1980, Progressing Cavity Pumps have been widely

used in the production of heavy oil well containing sand and gas.

The aim of this new edition is to provide clear related and condensed

information about the principles of the Progressing Cavity Pump, including

the use of recent material technologies to manufacture pump stators,

with advanced elastomers and now with metals. The same applies to

the drive rods and driving head, particularly with permanent magnet

motors and advanced control and well monitoring, with downhole

and surface sensors to control and monitor the pumping system. Data

transmission and processing are improving well management and

safety. Software is used to select the best pump for the well candidate.

All these new technologies are worldwide applied and accepted by

the market. They mean that well production can be increased and

PCP's operating life can be extended with reduced operating costs.

This book is intended to provide the criteria for selecting a Progressing

Cavity Pump and the operational conditions for its implementation

by technicians and field development managers.
