Patent ID: 8181703

Claim:
A method of fracturing a subterranean formation comprising: providing a treatment fluid comprising an aqueous base fluid and a relative permeability modifier, wherein the relative permeability modifier comprises a water-soluble polymer comprising a polymer backbone comprising polar heteroatoms and wherein the water-soluble polymer comprises at least one water-soluble polymer selected from the group consisting of: a hydrophobically modified polymer comprising a reaction product of a reaction comprising a hydrophilic polymer and a hydrophobic compound, wherein the hydrophobic compound is an organic acid; and, a hydrophobically modified polymer comprising a reaction product of a polymerization reaction comprising a hydrophilic monomer and a hydrophobically modified hydrophilic monomer wherein the hydrophobic modification is an organic acid; and positioning a hydrajetting tool in an interval of a well bore penetrating the subterranean formation; injecting the treatment fluid through the hydrajetting tool into the interval at a pressure sufficient to form a fracture in the subterranean formation; and then, injecting an acidizing fluid into the interval through the hydrajetting tool.
