Abstract
A non-toxic, environmentally friendly, green flowback aid is disclosed that reduces water blockage when injected into a fractured reservoir. The composition includes an water soluble ester of a low molecular weight alcohol and a low molecular weight organic acid, an oil soluble ester of a low molecular weight alcohol and a high molecular weight fatty acid, one or more water soluble or dispersible nonionic surfactant(s) derived from vegetable or animal sources, one or more anionic or amphoteric surfactant(s) derived from animal or vegetable based sources, and, water. Compositions for low temperature applications are also disclosed that can remain fluid down to −41° F.
