Abstract

A liquid additive composition comprising a particulate material, an organic carrier fluid, a viscosifier, and an alcohol alkoxylate surfactant; wherein the particulate material is substantially insoluble in the organic carrier fluid; wherein the particulate material comprises a water-interactive material and/or a water-insoluble material; wherein the organic carrier fluid comprises a glycol and/or a glycol ether; and wherein the viscosifier comprises amorphous silica. A method comprising (a) contacting a particulate material, an organic carrier fluid, a viscosifier, and an alcohol alkoxylate surfactant to form a mixture; and (b) agitating the mixture to form the liquid additive composition.
