TREATMENT FLUIDS CONTAINING POLYSACCHARIDES WITH FRICTION REDUCING GRAFTS THEREON

摘要

Method of treating a portion of a subterranean formation comprising: providing an aqueous-based treatment fluid comprising a friction-reducing grafted polymer wherein the friction-reducing grafted polymer comprises a friction-reducing polymer grafted to the polymer backbone; and, placing the aqueous-based treatment fluid into a portion of a subterranean formation. The treatment fluid may be (a) a fracturing fluid that is placed within the subterranean formation at a pressure sufficient to create or extend at least one fracture within the portion of the subterranean formation; (b) a gravel packing fluid, further including particulates, placed into a wellbore annulus within the subterranean formation to form a particulate pack therein; or (c) a frac-packing fluid, further including particulates, placed within the formation to pack a fracture within the formation with particulates and to fill a wellbore annulus within the subterranean formation adjacent to the fracture with a gravel pack.
