摘要：
A method of treating a formation containing crude oil with specific solubility groups and chemical families is described. The method includes (a) providing a hydrocarbon recovery composition to at least a portion of a formation containing crude oil with specific solubility groups and chemical families, wherein the composition comprises a C24-28 internal olefin sulfonate; and (b) allowing the composition to interact with hydrocarbons in the crude oil containing formation.
