Abstract
The present invention relates to improved low-quality particulates and methods of making such improved particulates. A method of treating a portion of a subterranean formation, comprising providing a slurry comprising a treatment fluid and low-quality particulates at least partially coated with an aqueous tackifying composition, wherein the aqueous tackifying composition comprises an aqueous tackifier compound and an aqueous liquid; introducing the slurry into a subterranean formation; and, depositing the coated, low-quality particulates into the portion of this subterranean formation. A method of improving particulates, comprising at least partially coating low-quality particulates with an aqueous tackifying composition, wherein the aqueous tackifying composition comprises an aqueous tackifier compound and an aqueous liquid.
