Abnormal decline in gas production rates and predicted ultimate recovery in many intermediate and deep artificially stimulated gas reservoirs in south Texas are brought about by a rapid decline in bottom-hole flowing pressures. The pressure drops occur due to crushing of sand proppants in the hydraulically created fractures. Additional factors contributing to the failure of the sand proppant are low reservoir permeabilities and high overburden pressures. Accelerated production rates intensify near well-bore pressure drawdowns which induce extreme closure pressures on the proppants. High-strength sintered bauxite proppants were introduced to the petroleum industry in late 1976 to provide fracture support under high closure pressure conditions. They have been subsequently applied to fracture design in Vicksburg sand, Edwards limestone, Wilcox sand, Frio sand, and Sligo limestone formations of south Texas. Laboratory tests of the sintered bauxite proppant with formation core samples were conducted that demonstrated superior flow capacities to sand under the higher closure pressures existing under producing conditions.
