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 an anionic surfactant based on an alkoxylated primary alcohol having a branched aliphatic group, which group has an average carbon number of from 9 to 15 and an average number of branches of from 0.5 to 2.5, and having an average of at least 0.5 mole of alkylene oxide groups per mole of primary alcohol; and (b) allowing the composition to interact with hydrocarbons in the hydrocarbon containing formation. Further, the invention relates to the hydrocarbon recovery composition that is used in said method. |
