Abstract
In a steam-foam-displacement of oil within a reservoir formation having a significant ion-exchange capacity for releasing multivalent cations, the rate of the steam foam propagation is increased by injecting a mixture of steam and a steam-foaming surfactant mixture comprising an independently effective steam-foaming sulfonate surfactant mixed with a lesser amount of an alkyl or alkylarylpolyalkoxyalkylene sulfonate cosurfactant.
