Progressing Cavity Pumps

The progressing cavity pump is a recent innovation in petroleum production. It rapidly gained an important place in the production of heavy oils containing gas. It has now been confirmed as very efficient for the production of large flow rates of light and abrasive oils. Driven by rod strings from the surface, it is a simple, rugged and cheap equipment. The aim of this book is to provide clear and condensed information related to the principles, qualities and performances of this system. This book is intended to provide the choice criteria of a progressing cavity pump and the operational conditions for its implementation by technicians and field development managers.
