Ely, J W; Tiner, R L

A method is described of fracturing a subterranean formation consisting of: (1) contacting the subterranean formation with a fracturing fluid produced by first solvating a basic aluminum soap of oil-soluble aliphatic carboxylic acids in liquid hydrocarbon to increase the viscosity of the liquid hydrocarbon; and thereafter dissolving benzoic acid in the liquid hydrocarbon to further increase the viscosity of the liquid hydrocarbon; (2) applying sufficient pressure to the fracturing fluid to open a fracture in the formation; and (3) maintaining the pressure while injecting the fluid into the fracture at a sufficient rate to extend the fracture into the formation.
