PROGRESSIVE CAVITY PUMPS PROVE MORE EFFICIENT IN MATURE WATERFLOOD TEST
Donny W. Wright Amoco Production Co. Odessa, Tex. Richard L. Adair Highland Pump Co. Odessa, Tex. For mature waterflood wells, field tests in the Permian basin indicate that progressive cavity (PC) pumps provide greater mechanical efficiency and use less electricity than beam and electric submersible pumps (ESP). The field tests are being conducted in wells that produce 500-1,000 b/d from 3,800-5,000 ft. The testing started in 1991 and will continue through 1993.
