Abstract: A wellbore treatment fluid is disclosed herein, the fluid comprising a butenediol vinyl alcohol copolymer. Also, a wellbore treatment fluid comprises a dissolvable material capable of forming a gel upon hydration, the dissolvable material having a cylindrical cross-sectional shape. Methods of treating a subterranean formation includes introducing a treatment fluid comprising a butenediol vinyl alcohol copolymer, and creating a plug with the treatment fluid.

Abstract: Methods of fracturing a subterranean formation include introducing a fracturing fluid containing an aqueous medium, a viscosifying agent and a polyethylene oxide alkyl ether through a wellbore and into the subterranean formation, pressurizing the fracturing fluid to fracture the subterranean formation, and allowing the fracturing fluid to flow back into the wellbore from the subterranean formation. The polyethylene oxide alkyl ether useful in some embodiments is defined according to the formula: where R1 and R2 are independently selected from linear or branched alkyl groups having from 2 to 16 carbon atoms, and ‘n’ may be a value selected from within a range of from 1 to 100.
