Abstract:
A method for reducing a permeability of at least one zone in a subterranean formation that includes introducing a treatment fluid to at least one permeable zone in a subterranean formation. The treatment fluid contains a solvent, a crosslinking agent, and a water-soluble polymer that is a copolymer of an acrylamide monomer and an n-vinyl amide monomer, or a terpolymer of an acrylamide monomer, an n-vinyl amide monomer, and an acrylic-acid based monomer. The treatment fluid is then allowed to crosslink and form a gel in the zone.

Claim (Index 15):
The method of  claim 1 , wherein the water soluble polymer is a terpolymer comprised of about 0.01 to about 70 mole percent of the acrylamide monomer, from about 30 to about 90 mole percent of the N-vinyl amide monomer and from about 0.01 to about 10 mole percent of the acrylic-acid based monomer and a stable gel is formed in the presence of waters containing divalent ions exceeding 2000 mg/L.
