ABSTRACT:
Conformance improvement is achieved in a subterranean hydrocarbon-bearing formation using a gel comprising a high molecular weight, water-soluble, carboxylate-containing polymer, a chromium III/carboxylate complex capable of crosslinking the polymer and an aqueous solvent. The gel components are combined at the surface and injected into the desired treatment zone via a wellbore to form a continuous single-phase gel.
