    摘要： The present invention provides a method of treating a hydrocarbon containing formation comprising (a) providing a hydrocarbon recovery composition to at least a portion of the hydrocarbon containing formation, wherein the composition comprises one or more internal olefin sulfonates having 17 or more carbon atoms, (b) adding water and/or brine from the hydrocarbon formation to the composition, (c) adding a solubilizer which comprises an ethoxylated alcohol wherein the alcohol before ethoxylation had an average molecular weight of at least about 220 and (d) allowing the composition to interact with hydrocarbons in the hydrocarbon containing formation. The solubilizer may comprise less than about 0.1 wt %, preferably from about 0.02 to about 0.05 wt %, of the total composition and it may have from about 5 to about 9 moles of ethylene oxide per mole of alcohol.

    摘要： 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.
