Kalpakci, B; Arf, T G

A method is described for recovering oil from a subterranean formation comprising injecting an aqueous composition into the formation and displacing the oil toward one or more production wells, the aqueous composition comprising: (A) from about 0.1% to about 5% by weight of at least one anionic or amphoteric surfactant; (B) from about 0.02% to about 0.3% byy weight of at least one polymeric thickener; and (C) from about 0.005% to about 0.1% by weight of at least one polymeric material having a flexible backbone and a higher polarizability than component (B).
