Surfactant flowback aids for use in subterranean formation operations

A method comprising:

• introducing into a subterranean formation a flowback aid composition comprising:
• an aqueous phase comprising an aqueous base fluid;
• an oil phase comprising a high-solvency oil;
• a surfactant blend comprising:
• a C8-C18 alcohol ethoxylate;
• 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;
• and
• a demulsifier 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.
