Abstract:
Surfactant compositions for treatment of subterranean formations and produced oil are disclosed. Methods of treating a subterranean formation include placing in the subterranean formation a surfactant composition. The surfactant composition includes an alkanolamide surfactant and an alkoxylated alcohol surfactant. The surfactant composition also includes an ionic surfactant, a nonionic surfactant, or a combination thereof, at least one compound according to Formula II:
