ABSTRACT:
A process employing a polymer gel in oil recovery applications. A gel is prepared by mixing a single aqueous gelation solution at the surface made up of a chromium acetate complex crosslinking agent and a mixture of an acrylamide polymer and guar gum polymer. The solution is injected into a desired treatment region and gelled to completion in situ.
