TUBING ROTATOR REDUCES TUBING WEAR IN ROD PUMPED WELLS
Marc Graham Mobil Exploration & Producing U.S. Midland, Tex. Charlie Brown Bock Specialties Inc. Arlington, Tex. Installation of tubing rotators has decreased tubing failures in West Texas waterflood sucker-rod pumped wells. Pumping unit movement powers the rotator system, turning the tubing string at about 1 revolution/day. The rotator System has both surface and subsurface components (Fig. 1).
