Abstract
Testing indicates that standard ESP gas separators will work with Progressive Cavity Pumps although Progressive Cavity Pumps operate at 1/10 the RPM and normally pump more viscous fluid than standard ESP equipment. Gas separators on standard equipment normally transfer the separated liquid to the centrifugal pump through an annular passage through the pump base. The Progressive Cavity Pumps base must incorporate a heavy-duty radial bearing for shaft support and has no room for adequate fluid passages. Normal application of Progressive Cavity Pumps requires larger passageways due to the viscosity of the fluid. The invention relates to methods to conduct the fluid around the bearing with little or no modifications to standard designs. This will allow the use of standard equipment without the expense of developing a new set of special gas separation devices and special Progressive Cavity Pumps systems.
