Abstract
A method of treating in a subterranean formation including combining a dimer acid; proppant; an emulsifier; an oil base fluid; and aqueous base fluid to form an oil-external emulsified fluid; and introducing the oil-external emulsified fluid into the subterranean formation. A method of forming a wellbore fluid including combining proppant; a dimer acid; an aqueous base fluid, an oil base fluid, and an emulsifier to form a pre-emulsified fluid; and mixing the pre-emulsified fluid to form an oil-external emulsified fluid.
