Abstract

1. A process for recovering oil from a subterranean oil-bearing formation containing high-salinity connate or flooding water, the formation being penetrated by a least one injection well and one production well which are in connection with the formation, by injection of an aqueous viscous solution of a polysaccharide, a hydroxy-alkylcellulose, a hydrophilic polyacrylamid or a hydrophylic vinyl acrylamide copolymer, characterized that an aqueous solution of polyethylene glycol and/polypropylene glycol or of a copolymer of ethylene oxide/propylene oxide having a molecular weight of from 800 to 2500, excepting 1240 to 2500, is either pre- or post-injected, or that polyethylene glyco and/or polypropylene glycol or, respectively, the copolymer is injected together with the polymer.
