SECONDARY OIL RECOVERY PROCESS USING BETA-SUBSTITUTED ACRYLAMIDE POLYMERS

An improved secondary recovery process which comprises injecting a viscous aqueous solution containing a beta-substituted acrylamide polymer, which can be partially hydrolyzed, if desired, into a subterranean oil-containing reservoir via an injection well, forcing the solution through the formation...
