Progressing Cavity Pumps

The Progressing Cavity Pump (PCP), invented by René Moineau, isa great innovation for the whole industry, particularly in petroleumproduction. Since 1980, Progressing Cavity Pumps have been widelyused in the production of heavy oil well containing sand and gas.The aim of this new edition is to provide clear related and condensedinformation about the principles of the Progressing Cavity Pump, includingthe use of recent material technologies to manufacture pump stators,with advanced elastomers and now with metals. The same applies tothe drive rods and driving head, particularly with permanent magnetmotors and advanced control and well monitoring, with downholeand surface sensors to control and monitor the pumping system. Datatransmission and processing are improving well management andsafety. Software is used to select the best pump for the well candidate.All these new technologies are worldwide applied and accepted bythe market. They mean that well production can be increased andPCP's operating life can be extended with reduced operating costs.This book is intended to provide the criteria for selecting a ProgressingCavity Pump and the operational conditions for its implementationby technicians and field development managers.
