摘要: A method and composition for improved enhanced oil recovery of from a subterranean hydrocarbon-bearing reservoir by effecting simultaneous mobility profile control in gas flooding which includes pre-injecting into the an aqueous solution water-soluble polymer combination with stable surfactant, followed injecting under pressure sufficient to effect production while recovering at producing well said reservoir.
