Abstract:
1. A method of diverting fluids in a subterranean formation, the method comprising: providing a first treatment fluid comprising an aqueous fluid and a relative permeability modifier comprising a hydrophobically modified water-soluble polymer that is: introducing the first treatment fluid into a well bore penetrating a subterranean formation such that the first treatment fluid penetrates into a portion of the subterranean formation in a sufficient amount so as to substantially divert a second treatment fluid to another portion of the subterranean formation wherein the second treatment fluid comprises an aqueous treatment fluid; introducing the second treatment fluid into the well bore; substantially diverting the second treatment fluid from the portion of the subterranean formation penetrated with the first treatment fluid to another portion of the subterranean formation; and, performing a well treatment operation using the second treatment fluid after the first treatment fluid has penetrated into the portion of the subterranean formation;
