Summary:A method for recovering oil from a subterranean formation is disclosed wherein a novel solution is injected into and driven through the formation. The solution contains an effective amount of surface-active agent having the general formula R1O(C3H6O)m (C2H4O)n YXwherein R, is a linear or branched alkyl radical, an alkenyl radical, or an alkyl or alkenyl substituted benzene radical, the non-aromatic portion of the radical containing from about 6 to about 24 carbon atoms;m has an average value of between about 1 and about 10;n has an average value of between about 1 and about 10;Y is a hydrophilic group; andX is a cation, preferably monovalent.
