Abstract:
A composition and method of fracturing a subterranean formation. The composition includes: about 0.25 wt. % to about 3.0 wt. %, based on a weight of the hydrocarbon liquid, of a mixture of phosphate esters, said esters selected from the group consisting of: monoester PO(OR1)(OH)2, PO(OR2)(OH)2; diester PO(OH)(OR1)m(OR2)2−m where m=0, 1, or 2; triester PO(OH)(OR1)n(OR2)3−n where n=0, 1, 2 or 3; and phosphoric acid H3PO4 wherein R1 and R2 each have 2 to 18 carbon atoms; and about 0.2 wt. % to about 1.0 wt. %, based on the weight of the hydrocarbon liquid, of an acidic polynuclear aluminum compound having an Al:Cl mole ratio ranging from about 1.40:1 to about 2.2:1. The composition is added to a hydrocarbon liquid to fracture the subterranean formation with this hydrocarbon liquid. The hydrocarbon liquid containing the composition exhibits a substantially constant viscosity.
