Abstract
The present invention relates to a new Winsor type IV microemulsion system for faster return of well service fluid and enhanced production of hydrocarbon-containing fluids in fractured tight subterranean formations, where the microemulsion system includes a surfactant subsystem including at least one glucamide sugar surfactant, a solvent subsystem and a co-solvent subsystem and to methods for making and using same.
