Aqueous gel-forming compositions useful for improving oil recovery from subterranean hydrocarbon-containing reservoirs are prepared by reacting an aminoalkylated polyacrylamide with an aldehyde, dialdehyde or derivative thereof in aqueous medium. These compositions are particularly effective in reducing excessive water encroachment at producer wells.
