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: A composition is described as including a mixture of citrus terpene hydrocarbons and an alcohol ethoxylate. The alcohol ethoxylate is represented by the formula R(C2H4O)nOH, where R is a branched or linear alkyl chain having from 12 to 15 carbons, and n is from 3 to 14. A method of removing pipe dope from a wellbore surface is also described. The method involves contacting the wellbore surface with the composition, and circulating the composition with respect to the wellbore surface. The pipe dope detaches from the wellbore surface and is dispersed in the composition, facilitating its removal.

Abstract: Systems, compositions, apparatus, and methods for hydraulically fracturing a subterranean formation traversed by a wellbore including mixing a gelling agent and water to form a base fluid, adding a gas and a proppant to the base fluid to form a foam fluid, alternating injecting into the formation the base fluid and the foam fluid, repeating the alternating injecting, forming regions of higher proppant concentration, and forming channels adjacent to the regions. Systems, compositions, apparatus, and methods for hydraulically fracturing a subterranean formation traversed by a wellbore including forming a base fluid with a gelling agent, forming a foam fluid with a gas and a proppant, injecting into the formation the base fluid, injecting into the formation the foam fluid, repeating the injecting the base fluid and foam fluid, and forming channels in the base fluid with faster flow than flow in the foam 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.

Abstract: Cement slurries are prepared that comprise water and a blend comprising an inorganic cement and particles with a sphericity between 0.5 and 0.9 and a Krumbein roundness between 0.5 and 0.9. The particles may comprise elastomers that impart flexibility to the set cement. The particles may be present at concentrations between 5% and 45% by volume of the slurry.
