Abstract
A process for fracturing a subterranean formation surrounding a gas or oil well which comprises injecting said subterranean formation under hydraulic pressure with a fluid comprising about 0.1 to about 75 percent of an interpolymer complex dissolved in a solvent system of a nonpolar organic liquid and a polar cosolvent (as desired), said polymer complex comprises the interaction product of a sulfonated polymer and an amine containing polymer, wherein the sulfonate content of the sulfonated polymer is about 4 meq. per 100 gram of polymer to about 200 meq. per 100 gram of polymer and the basic nitrogen content of the amine containing polymer is about 4 meq. per 100 gram of polymer to about 500 meq. per 100 gram of polymer, and by the addition of polar cosolvent to such solution of polymer complex modifying its rheological properties over a wide range and their subsequent use as fracturing fluids.
