Abstract: Methods include introducing a multistage treatment fluid into one or more intervals of a wellbore, wherein the treatment fluid contains one or more stages of a polymer-forming composition and one or more stages of a spacer fluid and initiating polymerization of the one or more stages of polymer-forming composition. Methods may include designing a multistage treatment fluid containing one or more stages of a polymer-forming composition and one or more stages of a spacer fluid, wherein or more stages of the polymer-forming composition comprises a thermosetting polymer; and pumping the multistage treatment fluid into a wellbore, wherein the pumping rate is determined by constructing a model based upon (a) the minimum pumping rate determined from the critical reaction temperature and the downhole temperature, (b) the fracture closing time, (c) the temperature within one or more fractures, and (d) the maximum pumping rate.

Abstract: Methods may include treating a subterranean formation penetrated by a wellbore, including: pumping a treatment fluid containing one or more polymeric proppants into the formation at a pressure sufficient to initiate a fracture, wherein the one or more polymeric proppants are composed of one or more polymers selected from a group of polyethylene, polypropylene, butylene, polystyrenes (PS) and copolymers thereof, high-impact grafted polystyrene (HIPS), acrylic polymers, methacrylic polymers, polyvinyl chloride (PVC), polyvinyl acetate (PVA), polycarbonate (PC), hydrogenated nitrile butadiene rubber (HNBR), ethyelene propylene diene monomer (EPDM), polydimethylsiloxane (PDMS), natural rubber, polystyrene-polybutadiene (PS-PB) copolymers, polymethylmethacrylate (PMMA), polystyrene-block-polymethylmethacrylate (PS-b-PMMA), acrylonitrile butadiene styrene (ABS), and epoxy resins. Methods may also include introducing a multistage treatment fluid comprising one or more stages of a polymeric proppant-containing fluid and one or more stages of a spacer fluid into one or more intervals of a wellbore.

Abstract: Embodiments may include methods that include emplacing a degradable material into a wellbore, wherein the degradable material includes a thermoplastic elastomer; contacting the degradable material with an aqueous fluid downhole; and allowing the degradable material to at least partially degrade. In another aspect, methods may include emplacing into a wellbore a tool containing a sealing element thereon, wherein the sealing element contains a degradable material; engaging the sealing element with a downhole surface to establish a seal; contacting the sealing element with an aqueous fluid; and allowing the sealing element to at least partially degrade, thereby disrupting the established seal.
