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 (C.sub.1-C.sub.50)hydrocarbyl amide having groups R.sup.1 and R.sup.2 substituted on the amide nitrogen, wherein R.sup.1 and R.sup.2 are each independently selected from the group consisting of —H, —(C.sub.1-C.sub.50)hydrocarbyl, and —(C.sub.1-C.sub.50)hydrocarbylene-OH, wherein at least one of R.sup.1 and R.sup.2 is —(C.sub.1-C.sub.50)hydrocarbylene-OH. The demulsifier composition includes an alkoxylated alcohol surfactant that is a (C.sub.1-C.sub.50)hydrocarbyl-OH having a —((C.sub.2-C.sub.3)alkylene-O).sub.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 (C.sub.1-C.sub.50)hydrocarbyl and (C.sub.1-C.sub.50)hydrocarbylene are substituted or unsubstituted and are independently selected.
