Abstract
A liquid additive composition comprising a particulate material, an organic carrier fluid, a deflocculant, and optionally a viscosifier and / or a surfactant; wherein the particulate material is substantially insoluble in the organic carrier fluid, and wherein the organic carrier fluid comprises a glycol and / or a glycol ether. A method comprising (a) contacting a particulate material, an organic carrier fluid, a deflocculant, and optionally a viscosifier and / or a surfactant to form a mixture; and (b) agitating the mixture to form the liquid additive composition.
