Abstract
A method of servicing a wellbore in a subterranean formation comprising preparing an invert emulsion comprising an aqueous fluid, an oleaginous fluid, and an emulsifier composition (EC), wherein the emulsifier composition comprises an emulsifier, a diluent, and a thinner, wherein the thinner comprises an alcohol, a fatty acid amide, or combinations thereof; and placing the invert emulsion in the wellbore. A method of servicing a wellbore in a subterranean formation comprising flowing a wellbore serving fluid comprising an emulsifier composition (EC) through a portion of a subterranean formation, wherein the EC comprises an emulsifier, a diluent and a thinner and wherein the thinner comprises 2-methyl-1-propanol, 2-methyl-2-butanol, a fatty acid amide, or combinations thereof; contacting the EC with oil in situ within the formation to form an emulsion; and reducing the water-oil interfacial tension and altering the wettability to provide enhanced oil recovery from the formation.
