Ceramic-coated proppant
A method of forming a ceramic-coated proppant, including receiving a proppant or particle and coating the proppant or particle with ceramic to give a ceramic coating on the proppant or particle. A method of hydraulic fracturing a geological formation with the ceramic-coated proppant.
Proppants and methods of making and use thereof
The present disclosure includes proppants and methods of making the proppants. The proppants herein may contain titanium dioxide, silicon dioxide, and/or aluminum dioxide. Also included in the present disclosure are methods of using the proppants to treat a reservoir.
Chemical products for adhesive applications
The embodiments described herein generally relate to methods and chemical compositions for coating substrates with a composition. In one embodiment, an adhesive composition is provided comprising a reaction product of a polyacid selected from the group consisting of an aromatic polyacid, an aliphatic polyacid, an aliphatic polyacid with an aromatic group, and combinations thereof, or a diglycidyl ether; and a polyamine; and one or more compounds selected from the group consisting of a branched aliphatic acid, a cyclic aliphatic acid with a cyclic aliphatic group, a linear aliphatic, and combinations thereof. The adhesive composition may be used to cover a substrate.
Process and system for enhanced depth penetration of an energy source
A method for enhanced depth penetration of energy into a formation may include mechanically stimulating proppant in proppant-containing fractures in the formation at a first frequency to induce mechanical stress in the proppant and directing electromagnetic radiation at a second frequency into the proppant-containing fractures of the formation while mechanically stimulating the proppant, wherein the first frequency and the second frequency are the same or different and wherein the proppant includes silica.
COATED PROPPANTS AND METHODS OF MAKING AND USE THEREOF
Coated proppants include a proppant particle, a surface copolymer layer surrounding the proppant particle, and a resin layer surrounding the surface copolymer layer. The surface copolymer layer includes a copolymer of at least two monomers chosen from styrene, methyl methacrylate, ethylene, propylene, butylene, imides, urethanes, sulfones, carbonates, and acrylamides, where the copolymer is crosslinked by divinyl benzene. The resin layer includes a cured resin. Methods of preparing the coated proppants include preparing a first mixture including at least one polymerizable material, an initiator, and a crosslinker including divinyl benzene; contacting the first mixture to a proppant particle to form a polymerization mixture; heating the polymerization mixture to cure the polymerizable material and form a polymer-coated particulate; preparing a second mixture including the polymer-coated substrate, an uncured resin, and a solvent; and adding a curing agent to the second mixture to cure the uncured resin and form the coated proppant.
Using Biodegradable Oils for Controlling Dust from Additive Particles
Application of biodegradable oils to additive particles to control dusting. A method of reducing an amount of dust produced during transfer of additive particles comprising: treating at least some of the additive particles with one or more biodegradable oils; storing the additive particles; and transferring the additive particles prior to and after storage, wherein biodegradable oil reduces the amount of dust produced during at least one of the transfers of the additive particles.
SALT TOLERANT SETTLING RETARDANT PROPPANTS
A method of treating a subterranean formation including suspending proppant particulates in a treatment fluid, wherein the proppant particles include a coating comprising a salt-tolerant, water-swellable polymer, and the treatment fluid includes at least one fluid consisting of fresh water, salt water, seawater, brine, an aqueous salt solution, and combinations thereof; and introducing the treatment fluid containing the settling retardant proppant particulates into the subterranean formation. A composite proppant particle includes a proppant substrate and a salt tolerant polymeric layer deposited on the proppant substrate.
Structural expandable materials
A composite particle that incorporates a material and is designed to undergo a reaction and/or mechanical or chemical change with the environment to increase in volume. The composite particle can be combined with a constraining matrix to create an expandable particle upon reaction. These particles can be used in stimulating wells, including oil and gas reservoirs.
