Summary:A method is described for treating a formation adjacent a subterranean well with a treatment fluid composition imparted with emulsion formation prevention properties. A microemulsion additive is mixed into a treatment fluid component to form a volume of a treatment fluid composition having emulsion formation prevention properties. The microemulsion additive is composed of a mixture solvent, a co-solvent, a mutual solvent, a non-emulsifier, a non-ionic surfactant, a non-ionic co-surfactant, alcohol, an emulsifying surfactant, and an aqueous fluid. The volume of the fluid composition is then injected into the subterranean well and contacts the formation, whereby the microemulsion additive in the treatment fluid volume acts to prevent emulsion formation in the formation.
