Patent ID: 8278250

Claim:
A method of diverting fluids in a subterranean formation, the method comprising: providing a treatment fluid comprising: an aqueous fluid, a scale inhibitor, and a relative permeability modifier comprising a hydrophobically modified water-soluble polymer that is: synthesized from a reaction between a hydrophilic polymer and a hydrophobic compound comprising an alkyl group having from about 7 to about 22 carbon atoms, or synthesized from a polymerization reaction between a hydrophilic monomer and a hydrophobically modified hydrophilic monomer, the hydrophobically modified hydrophilic monomer comprising an alkyl group having from about 7 to about 22 carbon atoms and the hydrophobically modified hydrophilic monomer being selected from the group consisting of: an alkyl acrylate; an alkyl methacrylate; an alkyl acrylamide; an alkyl methacrylamide; an alkyl dimethylammoniumethyl methacrylate halide; and an alkyl dimethylammoniumpropyl methacrylamide halide; introducing a first portion of the treatment fluid into a well bore penetrating a subterranean formation; allowing the first portion of the treatment fluid to penetrate into a portion of the subterranean formation in a sufficient amount so as to substantially divert a second portion of the treatment fluid or a different aqueous treatment fluid to another portion of the subterranean formation; and introducing the second portion of the treatment fluid or the different aqueous treatment fluid into the subterranean formation.
