<p>A method for fracturing subterranean formations at a subterranean environmental temperature above 150 DEG F. which includes the steps of initially preparing an oil base gel consisting essentially of a hydrocarbon liquid containing an aluminum salt of a phosphate ester, then adding to said gel, at a temperature below about 150 DEG F., a gel-insoluble, solid aluminum salt of a phosphate ester to form a pumpable dispersion, and finally pumping the slurry down a bore hole and into the formation to be fractured.</p> |
