摘要: A process for use with a polymer which is crosslinkable by reaction an amino resin, comprises the steps of determining period time within full gelation to be achieved; preparing gel-forming aqueous-based mixture comprising polymer, rapid resin crosslinking agent and delayed agent, capable complete so determined; partially gelling reacting effective partial four hours; fully determined. method enhancing recovery oil from subterraean oil-bearing formation also provided.
