摘要： A coated proppant having a proppant particle, an intermediate cross-linked terpolymer layer encapsulating the proppant particle, and an outer resin layer encapsulating the intermediate cross-linked terpolymer layer. The proppant particle is selected from sand, ceramic, glass, and combinations thereof. The intermediate cross-linked terpolymer layer includes styrene, methyl methacrylate, and divinyl benzene. The outer resin layer includes a cured epoxy resin formed from an epoxy resin and a curing agent.

摘要： A proppant including polyolefin-coke composite granules, a hydrocarbon well including such a proppant, and methods of forming the hydrocarbon well using such a proppant are provided herein. The hydrocarbon well includes a wellbore that extends within a subsurface region and a downhole tubular that extends within the wellbore and defines a tubular conduit. The hydrocarbon well also includes a number of perforations formed within the downhole tubular and a number of fractures formed within the subsurface region proximate to the perforations. The hydrocarbon well furthers include the proppant positioned within at least a portion of the fractures. The proppant includes a number of polyolefin-coke composite granules, where a characteristic dimension of each polyolefin-coke composite granule is at least 50 micrometers (μm) and at most 3 millimeters (mm), and where each polyolefin-coke composite granule includes a number of polyolefin polymer chains and at least one petroleum coke granule.

摘要： Bioinspired chemical additives, coating, or/and solution, in mimicking biomineralization processes of bone, useful for enhancing the strength of hydraulic- cement concrete and mitigating the risk of its cracking failure, comprising of micro/nano/textured dual phobic dot domains as core layer, hydrogel polymer as shell, prepared by water and mineral oil as solvent via surfactant/emulsifier as intermediate layer encapsulated in an emulsion, were mixed with cement, fine sand, and aggregates by weight percentage at a mix ratio of from 0.00001/99.99999 to 10.0/90, of which the ratio of water to cement is ranged from 0.2 to 0.80 (W/C), the volume fraction of cement accounted for total volume fraction of solid from 5 to 50%, the fine sand from 40% to 90%, and aggregate from 40% to 90% as water dried, a replacement of cement with cementitious materials such as microcrystalline silica sand, micro gel, and swollen clays ranged from 0.01% to 75% over the cement by weight percentage, casted into concrete blocks having an early age of compressive strength of more than 4000 (PSI) within 24 hour, Brazilian splitting tensile strength of more than 1000 (psi) at 28 days, ultimate compressive strength of more than 7500 (PSI) after exposed at the ambient conditions for over one and half year, an increased toughness of more than 900 (%), modulus of resilience of more than 1300 (%), self-healing capability of more than 80(%) by pre-cracking test method, density ranged from 1.90 to 2.55 (g/cm3), moisture content loss of less than 3.0%, resulting from the contributions of the tunable self- assembly of dispersive and non-covalent bonds in response to the exothermic hydration of micro/nano/textured hydro dual phobic domains of proteins, wax, and hydrogel polymers with mixed concrete components from 30 to 200 °F.
