Abstract:
The present invention relates to a composition for an enhanced oil recovery process, said composition comprising
(a) one or more anionic cocogem surfactants;
b) one or more surfactants based on nonionic vegetable fatty acids (or their synthetic analogues);
c) optionally one or more, preferably commercially available, co-surfactants;
d) optionally one or more agents with phase transfer property, preferably an alcohol; and
e) polyacrylamide as a flow modifier.
