Title: Aqueous-based tackifier fluids and methods of use

Abstract: The present invention relates to aqueous based tackifier fluids and their use in stabilizing particulates in propped fractures. Some embodiments of the present invention provide methods of creating a proppant pack in a subterranean formation, comprising introducing an aqueous servicing fluid comprising proppant particulates, wherein at least some of the proppant particulates are at least partially coated with an aqueous tackifier compound, into a subterranean fracture; and, activating the aqueous tackifier compound so as to form a proppant pack. Other embodiments provide methods of stabilizing a proppant pack comprising introducing an aqueous tackifier compound to at least a portion of an existing proppant pack; and, activating the aqueous tackifier compound so as to stabilize the proppant pack. Other embodiments provide servicing fluids comprising proppant particulates and an aqueous fluid wherein at least some of the proppant particulates are at least partially coated with an aqueous tackifier compound.
