Beschreibung
Zusammenfassung:	The invention relates to a method of treating a hydrocarbon containing formation, comprising: (a) providing a composition to at least a portion of the hydrocarbon containing formation, wherein the composition comprises water and an anionic surfactant which is an internal olefin sulfonate (IOS), which has a weight ratio of branched IOS molecules to linear IOS molecules N which is greater than 0 to smaller than 11:89; and (b) allowing the composition to interact with the hydrocarbons in the hydrocarbon containing formation. Further, the invention relates to a hydrocarbon recovery composition which comprises the composition used in said method, and to a hydrocarbon containing composition produced from a hydrocarbon containing formation which in addition to hydrocarbons contains the composition used in said method.
