Abstract
An artificial lift system used to produce fluids from boreholes such as oil and gas wells. The system uses a progressive cavity (PC) downhole pump system which can be inserted into the borehole, seated, operated, flushed and removed using conventional or coiled sucker rod tubing. The progressive cavity pump system includes a tubular body with a stator and a rotor within the stator. The rotor is connected to a rotatable string on one end and an arrowhead assembly on the other. A seating mandrel assembly maintains the rotor within the stator. The seating mandrel assembly has a component configured to engage with the arrowhead assembly so that the pump may be removed from a downhole location.
