| titleOfInvention | Demulsifier compositions for treatment of subterranean formations and produced oil |
| abstract | Various embodiments disclosed relate to demulsifier compositions for treatment of subterranean formations or produced petroleum comprising an emulsion. In various embodiments, the present invention provides a method of treating a subterranean formation. The method includes placing in the subterranean formation a demulsifier composition. The demulsifier composition includes an alkanolamide surfactant that is a (C1-C50)hydrocarbyl amide having groups R1 and R2 substituted on the amide nitrogen, wherein R1 and R2 are each independently selected from the group consisting of —H, —(C1-C50)hydrocarbyl, and —(C1-C50)hydrocarbylene-OH, wherein at least one of R1 and R2 is —(C1-C50)hydrocarbylene-OH. The demulsifier composition includes an alkoxylated alcohol surfactant that is a (C1-C50)hydrocarbyl-OH having a —((C2-C3)alkylene-O)n—H group on the —OH group, wherein n is about 1 to about 100. The demulsifier composition also includes an amine-oxide surfactant. At each occurrence the (C1-C50)hydrocarbyl and (C1-C50)hydrocarbylene are substituted or unsubstituted and are independently selected. |
