Abstract
The present invention includes methods and compositions that include a resin composition comprising from about 5% to about 30% phenol, from about 40% to about 70% phenol formaldehyde, from about 10 to about 40% furfuryl alcohol, from about 0.1% to about 3% of a silane coupling agent, and from about 1% to about 15% of a surfactant and methods of using of that resin in controlling particulate flowback from a subterranean formation.
Claims
exact text as granted — not AI-modified1 . A method comprising:
providing a resin composition comprising:
about 5% to about 30% phenol by weight of the resin composition;
about 40% to about 70% phenol formaldehyde by weight of the resin composition;
about 10% to about 40% furfuryl alcohol by weight of the resin composition;
about 0.1% to about 3% of a silane coupling agent by weight of the resin composition; and
about 1% to about 15% of a surfactant by weight of the resin composition;
providing proppant particles; coating the resin composition onto at least a portion of the proppant particles to create resin-coated proppant particles; introducing the resin-coated proppant particles into a subterranean zone; and allowing at least a portion of the resin composition on the resin-coated proppant particles to substantially cure.
2 . The method of claim 1 wherein the silane coupling agent comprises at least one silane coupling agent selected from the group consisting of: N-2-(aminoethyl)-3-aminopropyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, and n-beta-(aminoethyl)-gamma-aminopropyl trimethoxysilane.
3 . The method of claim 1 wherein the surfactant comprises at least one surfactant selected from the group consisting of: ethoxylated nonyl phenol phosphate ester, a cationic surfactant, a non-ionic surfactant, and an alkyl phosphonate surfactant.
4 . The method of claim 1 wherein the amount of the resin composition coated onto the portion of the proppant particles is about 0.1% to about 5% by weight of the portion of the proppant particles.
5 . The method of claim 1 wherein the resin composition further comprises a solvent.
6 . The method of claim 5 wherein the solvent comprises at least one solvent selected from the group consisting of: 2-butoxy ethanol, butylglycidyl ether, dipropylene glycol methyl ether, dipropylene glycol dimethyl ether, dimethyl sulfoxide, dimethyl formamide, diethyleneglycol methyl ether, diethylene glycol dimethyl ether, ethyleneglycol butyl ether, diethyleneglycol butyl ether, gamma-butyrolactone, butylene carbonate, propylene carbonate, ethylene carbonate, methanol, butyl alcohol, d-limonene, and a fatty acid methyl ester.
7 . A method comprising:
providing a resin composition comprising:
about 5% to about 30% phenol by weight of the resin composition;
about 40% to about 70% phenol formaldehyde by weight of the resin composition;
about 10% to about 40% furfuryl alcohol by weight of the resin composition;
about 0.1% to about 3% of a silane coupling agent by weight of the resin composition; and
about 1% to about 15% of a surfactant by weight of the resin composition;
providing proppant particles; coating the resin composition onto at least a portion of the proppant particles to create resin-coated proppant particles; introducing the resin-coated proppant particles into a fracture in a subterranean zone; and allowing at least a portion of the resin composition on the resin-coated proppant particles to substantially cure.
8 . The method of claim 7 wherein the silane coupling agent comprises at least one silane coupling agent selected from the group consisting of: N-2-(aminoethyl)-3-aminopropyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, and n-beta-(aminoethyl)-gamma-aminopropyl trimethoxysilane.
9 . The method of claim 7 wherein the surfactant comprises at least one surfactant selected from the group consisting of: ethoxylated nonyl phenol phosphate ester, a cationic surfactant, a non-ionic surfactant, and an alkyl phosphonate surfactant.
10 . The method of claim 7 wherein the amount of the resin composition coated onto the portion of the proppant particles is about 0.1% to about 5% by weight of the portion of the proppant particles.
11 . The method of claim 7 wherein the resin composition further comprises a solvent.
12 . The method of claim 11 wherein the solvent comprises at least one solvent selected from the group consisting of: 2-butoxy ethanol, butylglycidyl ether, dipropylene glycol methyl ether, dipropylene glycol dimethyl ether, dimethyl sulfoxide, dimethyl formamide, diethyleneglycol methyl ether, diethylene glycol dimethyl ether, ethyleneglycol butyl ether, diethyleneglycol butyl ether, gamma-butyrolactone, butylene carbonate, propylene carbonate, ethylene carbonate, methanol, butyl alcohol, d-limonene, and a fatty acid methyl ester.
13 . The method of claim 7 further comprising:
providing a fracturing fluid; mixing the resin-coated proppant particles into the fracturing fluid; and introducing the fracturing fluid comprising the resin-coated proppant particles into the subterranean zone at a pressure sufficient to extend the fracture in the subterranean zone or create at least one other fracture in the subterranean zone.
14 . The method of claim 13 wherein the fracturing fluid comprises at least one fluid selected from the group consisting of: an aqueous gel and an emulsion.
15 . The method of claim 13 wherein the fracturing fluid comprises at least one additive selected from the group consisting of: a breaker, a stabilizer, a fluid loss control additive, a clay stabilizer, and a bactericide.
16 . The method of claim 13 wherein the fracturing fluid comprises at least one fluid selected from the group consisting of: fresh water, salt water, brine, and seawater.
17 . The method of claim 13 wherein the fracturing fluid comprises an aqueous gel comprised of:
water; a gelling agent; and a cross-linking agent.
18 . A method comprising:
providing a resin composition comprising:
about 5% to about 30% phenol by weight of the resin composition;
about 40% to about 70% phenol formaldehyde by weight of the resin composition;
about 10% to about 40% furfuryl alcohol by weight of the resin composition;
about 0.1% to about 3% of a silane coupling agent by weight of the resin composition; and
about 1% to about 15% of a surfactant by weight of the resin composition;
providing an initial portion of proppant particles, a middle portion of proppant particles, and a last portion of proppant particles; coating the resin composition onto at least the initial portion of proppant particles and the last portion of proppant particles to create an initial portion of resin-coated proppant particles and a last portion of resin-coated proppant particles; introducing the initial portion of resin-coated proppant particles into a fracture in a subterranean zone; introducing the middle portion of proppant particles into the fracture in the subterranean zone; introducing the last portion of resin-coated proppant particles into the fracture in the subterranean zone; and allowing at least a portion of the resin composition on the initial portion of resin-coated proppant particles and on the last portion of resin-coated proppant particles to substantially cure.
19 . The method of claim 18 wherein the resin composition is not applied to the middle portion of proppant particles.
20 . The method of claim 18 further comprising applying the resin composition intermittently to the middle portion of proppant particles.Cited by (0)
