ABSTRACT:
An improved process for recovering oil by flowing a mixture of steam and steam foam surfactant into an oil-containing subterranean reservoir, the improvement provided by using surfactants enriched in olefin disulfonate. The surfactants may be used in either a steam drive or a steam soak process. Disulfonate-enriched steam foam surfactants and mixtures are also described.
