18. A method of servicing a wellbore comprising:
-
placing a composition comprising an acetate and/or lactate ester and excluding a mutual solvent precursor into contact with oil-wet solids in the wellbore under conditions; wherein the acetate and/or lactate ester hydrolyzes to release acetic and/or lactic acid; wherein the acetic and/or lactic acid catalyzes the hydrolysis of additional acetate and/or lactate ester; and wherein all or a portion of the acetate and/or lactate ester converts at least a portion of the oil-wet solids to water-wet solids. - View Dependent Claims (19, 20)
