Deep well stimulation in the Anadarko Basin

New materials and techniques developed for deep, high-temperature wells have made it possible to design stimulation treatments to more economically produce desired results with greater savings in completion costs. New inhibitors plus a cool-down treating technique have greatly improved acidizing results. Highly viscous fracture fluids have made it possible to hydraulically fracture effectively at low injection rates. The various methods and materials being used for the deep reservoirs encountered in the Anadarko Basin are discussed.
