Abstract
A method, comprising contacting a proppant, water, and a water external emulsion to form a mixture, wherein the water external emulsion has an organic internal phase comprising a surface modifying agent; contacting the mixture with an emulsion breaker to form a wellbore servicing fluid comprising a proppant coated with the surface modifying agent; an placing the wellbore servicing fluid in a wellbore penetrating a subterranean formation. A method comprising contacting a proppant, water, and a water external emulsion to form a first mixture, wherein the water external emulsion has an organic internal phase comprising a surface modifying agent; contacting the first mixture with an emulsion breaker to form second mixture comprising a proppant coated with the surface modifying agent; and recovering a coated proppant from the second mixture.
