Abstract
An improved steam injection process for recovering hydrocarbons from a subterranean formation. The process includes the use of alpha-olefin sulfonate dimer surfactants in the steam to form a foam-steam drive medium which is injected into the formation through at least one injection well to enhance the recovery of hydrocarbons from at least one production well.
