Patent ID: 7938187

Claim:
A method of treating a subterranean formation comprising: providing an aqueous treatment fluid comprising a polysaccharide, a dual functional component, and a plurality of proppant particulates; wherein the polysaccharide is not xanthan or a galactomannan; wherein the dual functional component comprises a salt of a percarbonate; wherein the aqueous treatment fluid has a first viscosity; allowing the dual functional component to interact with the polysaccharide so as to increase the first viscosity of the aqueous treatment fluid to a second viscosity wherein the second viscosity is greater than the first viscosity in the absence of a crosslinker; placing the aqueous treatment fluid into a subterranean formation; and allowing the dual functional component to interact with the polysaccharide so as to reduce the second viscosity of the aqueous treatment fluid to a third viscosity wherein the third viscosity is less than the second viscosity in the absence of a breaker.
