ABSTRACT:
A process for recovering crude oil from a subterranean formation comprising injecting into the formation a liquid composition consisting essentially of a specific surfactant in an aqueous medium, driving the liquid composition through said formation to displace oil from said formation and recovering said oil in a production well. The surfactant has the general formula ##STR1## wherein R.sup.1 =C.sub.1 -C.sub.30 alkyl or alkylaryl, R.sup.2 =C.sub.2 H.sub.4 or C.sub.3 H.sub.6, R.sup.3 =C.sub.2 H.sub.4 or C.sub.3 H.sub.6, R.sup.4 =C.sub.1 to C.sub.12 alkyl or alkylaryl, R.sup.5 =H or C.sub.1 -C.sub.12 alkyl or alkylaryl, x and y are integers from 0 to 100, and z is an integer from 1 to 4.
