Paper: Insertable Progressing Cavity Pumps

National-Oilwell is the Distributor for a newly patented line of Insertable Progressing Cavity Pumps. This new technology allows the producer to install and remove both the rotor and stator with the sucker rod string. The tubing string contains a down-hole seating assembly attached to the bottom, which stays in place until the tubing is removed from the well. The improved efficiencies and state of the art elastomer materials are all combined to significantly reduce the lifting costs for today's producer. These pumps have the ability to move many different fluids including: oil, water, high viscosity fluids, and fluids containing solids such as sand, coal, or formation fines.
