An effective stimulation treatment requires the interaction of four separate items: frac fluids, proppants, equipment, and planned and properly engineered schedules. While there are good fluid systems and proppants, only judicious combinations and a well thought out schedule which uses all of these materials and available equipment to best advantage is an optimum stimulation treatment. Generally, high flow rates and convective cooling can be used either with conventional (planar) fracturing or with a dendritic fracturing technique. Many of todays fluid systems have been tested to above 400/sup 0/F. Some fluids have survived quite well. Current tests on proppants have shown temperature sensitivities in sand; however, there are resin coated materials and sintered bauxite which are not temperature sensitive. (MHR)
