Abstract
Methods for controlling particulate segregation comprising providing a mixture of an aqueous tackifying composition with a treatment fluid; slurrying the mixture with a first type of solid particulates and a second type of solid particulates and wherein the first type of solid particulates have a tendency to segregate from the second type of solid particulates when slurried into a liquid; and, placing the slurry into a portion of a subterranean formation. Methods for controlling particulate segregation comprising providing a treatment fluid; at least partially coating with an aqueous tackifying composition: a first type of solid particulates and a second type of solid particulates and wherein the first type of solid particulates have a tendency to segregate from the second type of solid particulates when slurried into a liquid; slurrying the two types of particulates into the treatment fluid; and, placing the slurry into a portion of a subterranean formation.
