ABSTRACT:
An improved non-condensible gas injection process for recovering hydrocarbons from a subterranean formation. The process includes the use of alpha-olefin sulfonate monomer and alpha-olefin sulfonate dimer surfactants along with the gas to form a gas-foam 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.
