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 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. L'invention concerne un procédé de traitement d'une formation contenant des hydrocarbures, comprenant : (a) la fourniture d'une composition dans au moins une partie de la formation contenant des hydrocarbures, la composition comprenant un tensioactif anionique basé sur un alcool primaire alcoxylé ayant un groupe aliphatique ramifié, ledit groupe ayant un nombre moyen de carbones de 9 à 15 et un nombre moyen de branchements de 0,5 à 2,5, et ayant une moyenne d'au moins 0,5 mole de groupes oxydes d'alkylène par mole d'alcool primaire; et (b) laisser la composition interagir avec des hydrocarbures dans la formation contenant des hydrocarbures. De plus, l'invention concerne la composition de récupération d'hydrocarbures qui est utilisée dans ledit procédé.
