Beschreibung
Zusammenfassung:	A method of treating a hydrocarbon containing formation is described. The method may include providing a hydrocarbon recovery composition to the hydrocarbon containing formation. Hydrocarbons in the hydrocarbon containing formation may interact with the hydrocarbon recovery composition. The hydrocarbon recovery composition may include an aliphatic anionic surfactant and an aliphatic nonionic additive. In some embodiments, an aliphatic anionic surfactant may be branched. In other embodiments, an aliphatic nonionic additive may be branched. L'invention concerne un procédé de traitement de formation contenant des hydrocarbures, qui peut consister à introduire une composition de récupération correspondante dans la formation considérée. Les hydrocarbures de cette formation peuvent entrer en interaction avec la composition, laquelle peut comprendre un tensioactif aliphatique anionique et un additif aliphatique non ionique. Selon certaines variantes, on peut ramifier un tensioactif aliphatique anionique. Selon d'autres variantes, on peut ramifier un additif aliphatique non ionique.
