摘要： 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.

摘要： Methods may include introducing a polymerizable composition containing a polycyclic monomer and a catalyst into a subterranean formation; and polymerizing the polymerizable composition in the presence of the catalyst in situ to form a polymer. Methods may also include lowering a wellbore tool into the subterranean formation, wherein the tool contains a first partition containing a polymerizable composition, and a second partition containing a catalyst; releasing the polymerizable composition from the first partition; releasing the catalyst from the second partition; contacting the polymerizable composition and the catalyst in a mixing region; and reacting the polymerizable composition and the catalyst in situ to form a polymer.

摘要： 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.

摘要： Degradation agent encapsulation is provided. In one possible implementation, a capsule includes a degradation agent configured to encourage degradation of the part and a coating at least partially encapsulating the degradation agent. The coating is engineered to be compromised upon exposure to one or more activation triggers. In another possible implementation, a degradable part includes one or more capsules embedded in the part. The capsules include a degradation agent at least partially encapsulated in a coating engineered to be compromised upon exposure to one or more activation triggers.

摘要： Embodiments may generally take the form of a degradable composite structure and a method for controlling the rate of degradation of a degradable composite structure. An example embodiment may take the form of a degradable polymer matrix composite (PMC) including a matrix having: a degradable polymer, a fiber reinforcement, and particulate fillers. The fiber loading is between approximately 10% to 70% by weight and the particulate loading is between approximately 5% to 60%.

摘要： 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.

摘要： A degradable composite composition including polyglycolic acid and a boron-containing accelerator, and methods of using the same (for example, as a constituent of a treatment fluid of a subterranean formation) are described. The degradable composite composition may be a composition that degrades in environments typically encountered downhole, such as oilfield environments/conditions and/or fluids.
