ABSTRACT:
A method for enhanced oil recovery in a reservoir having a substantial silicon content where an organosilicone surfactant is co-injected with steam to generate a foam. The organosilicone surfactant component of the foam prevents a dissolution of the silicon-containing formation since local equilibrium is assured. Prevention of formation dissolution reduces caving near the wellbore and minimizes permeability reduction away from the wellbore.
