Gas flood surfactants enriched in olefin disulfonate
摘要:
Improved gas foam flooding surfactants and gas foam-forming mixtures wherein the surfactants are enriched in olefin disulfonate. The surfactants may be used in either a gas drive or a gas soak process. Use of the disulfonate-enriched gas foam surfactants and mixtures in a gas flooding operation is also described.
