Docket 850003-E DELAYED IN SITU CROSSLINKING OF ACRYLAMIDE POLYMERS FOR OIL RECOVERY APPLICATIONS IN HIGH-TEMPERATURE FORMATIONS ABSTRACT A process for treating a region in a high-temperature hydrocarbon-bearing formation with a gel for hydrocarbon recovery applications. The gel is prepared by mixing a single aqueous gela- tion system at the surface comprising a solution of a polyvalent metal crosslinking agent and an unhydrolyzed acrylamide polymer. The system is injected into a desired treatment region of the high- temperature formation wherein the polymer is hydrolyzed in situ. The gelation system is then yelled to completion in the treatment region. RFB:bcp
