ABSTRACT:
A mixture of propoxylated and ethoxylated surfactants is provided, along with a method to displace water flood residual oil from subterranean formations utilizing this mixture. The mixture is considerably less expensive than surfactants containing both propoxy and ethoxy groups, but provides the advantages of a graded lipophilic to hydrophilic structure of such surfactants.
