ABSTRACT:
Method of treating a portion of a subterranean formation comprising: placing a pre-pad fluid into a portion of a subterranean formation wherein the pre-pad fluid comprises a low-viscosity aqueous tackifying composition that comprises an aqueous tackifier compound and an aqueous fluid; placing a fracturing fluid into the portion of the subterranean formation at a pressure sufficient to create or extend at least one fracture therein; and, activating the aqueous tackifier compound with an activator so as to consolidate the unconsolidated particulates. Method of consolidating unconsolidated particulates within a portion of a subterranean formation comprising: placing a foamed low-viscosity aqueous tackifying composition into a portion of a subterranean formation comprising unconsolidated particulates wherein the aqueous tackifying composition comprises an aqueous fluid, a foaming agent, and an aqueous tackifier compound; and, activating the aqueous tackifier compound with an activator so as to consolidate the unconsolidated particulates.
