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.
