Abstract

Process for recovering oil from a reservoir penetrated by at least one injection well comprising injecting into the reservoir a gas-foam forming mixture comprising an aqueous surfactant solution and a gas mixture including a noncondensible gas, displacing within the reservoir the gas foam-forming mixture, and withdrawing oil from the reservoir, wherein the surfactant contains at least 25 wt%
olefin disulfonate.
