Claim 7:
8. A method of hydraulic fracturing, the method comprising:
passing a fracturing fluid through a wellbore into a subterranean formation, wherein the fracturing fluid comprises a flowback enhancer composition in an amount of from 0.10 gallon per 1000 gallons of fluid (gpt) to 10 gpt based on the total volume of fracturing fluid;
hydraulically fracturing the subterranean formation with the fracturing fluid, thereby generating fractures in the subterranean formation;
passing the fracturing fluid to a surface of the well, wherein the fracturing fluid is mixed with hydrocarbons; and
at least partially separating the fracturing fluid from the hydrocarbons to yield a recovered fracturing fluid;
wherein the flowback enhancer composition comprises:
a solvent mixture comprising an aqueous solution, at least methyl-9-dodecenoate, and at least isopropanol;
a surfactant mixture comprising at least dodecylbenzene sulfonic acid and a castor oil ethoxylate; and
one or more particles having a widest length of from 1 nanometer to 200 nanometers.
