The Permian Basin of W. Texas and SE. New Mexico embraces literally thousands of wells that have become marginal producers or stripper wells. Bottom-hole pressures have declined to a point that makes reverse-circulation type workovers impractical in many instances. Following the outstanding success of foam workovers in California, Chevron Research Co. has appointed several Well Servicing contractors in the Permian Basin area as Lincensee permitting them to perform similar foam workover operations. While still new in this area, the same degree of success is being obtained. A number of successful cleanout, deepening, and formation coring operations have been performed in low bottom-hole pressure wells, when circulation using fluids would be impractical or very damaging to the producing formation. Foam has proved more successful than using gas for circulation, because it will circulate at less bottom-hole pressure, carry more cuttings or sand at comparable circulation rates and is less expensive. A description of the foam unit being used, and how foam is generated and applied are described.
