<p>A process for controlling the gelation rate of a carboxylate-containing polymer used in oil recovery applications. A gel is prepared by mixing a single aqueous gelation solution at the surface made up of the polymer and a crosslinking agent containing a chromic carboxylate complex and an inorganic chromic salt. The concentration of the inorganic chromic salt is selected at a level which achieves the desired rate of gelation for a given application.</p> |
