Abstract:
The embodiments herein relate generally to subterranean formation operations and, more particularly, to surfactant flowback aids for use in subterranean formation operations. The surfactant flowback aid composition may comprise an aqueous phase comprising an aqueous base fluid, a surfactant blend, and a demulsifier. The surfactant blend may comprise a C8-C18 alcohol ethoxy-late; a fatty acid alkanolamide; and optionally, a surfactant selected from the group consisting of a non-ionic surfactant, an anionic surfactant, a cationic surfactant, an amphoteric surfactant, and any combination thereof. The demulsifier may be selected from the group consisting of a desalter agent to separate water from crude oil, a treater agent to flocculate submicron particulates from crude oil, and any combination thereof.
