Abstract
A non-crosslinking salt of a monovalent cation is added to a gelation solution comprising an acrylamide polymer and a redox crosslinking system to render the viscosity and uniformity of the resulting gel less sensitive to the concentrations of the gel components. The gel is used for conformance correction treatments of subterranean hydrocarbon-bearing formations to reduce the permeability of a high permeability zone adjacent a low permeability zone.
