Non-condensible gas injection including alpha-olefin sulfonate surfactant additives |
摘要 |
An improved non-condensible gas injection process for recovering hydrocarbons from a subterranean formation. The process includes the use of alpha-olefin sulfonate surfactants along with the non-condensible gas to form a gas-foam drive medium which is injected into the formation through at lest one injection well to enhance the recovery of hydrocarbons from at least one production well.
