Abstract

Various embodiments disclosed relate to a curable composition and resin for treatment of a subterranean formation. In various embodiments, the present invention provides a method of treating a subterranean formation. The method can include placing in a subterranean formation a curable composition. The curable composition can include an epoxy silane monomer, a hardener, and carrier fluid. The curable composition can include an epoxy monomer, an amine silane hardener, and carrier fluid. The method can also include curing the curable composition to form an epoxy silane resin.

First claim

What is claimed is:

1. A curable composition for treatment of a subterranean formation, the curable composition comprising:
an epoxy monomer and a hardener, wherein the epoxy monomer is an epoxy silane monomer configured to be curable by the hardener; and
a carrier fluid,
wherein the epoxy monomer is an epoxy silane monomer selected from

wherein about 55 wt. % to about 70 wt. % of the curable composition is the epoxy silane monomer;
wherein the hardener is

wherein n is about 1 to about 4,
wherein about 15 wt. % to about 35 wt. % of the curable composition is the hardener; and
wherein the carrier fluid comprises water, wherein about 5 wt. % to about 25 wt. % of the curable composition is the carrier fluid.

2. The curable composition of claim 1 , wherein the curable composition further comprises a downhole fluid.

3. The curable composition of claim 1 , wherein the curable composition is a composition for at least one of remediating and consolidating a subterranean formation.

4. The curable composition of claim 1 , wherein the curable composition is a composition for at least one of cementing and plugging a subterranean formation.

5. An epoxy silane resin cured reaction product of the curable composition of claim 1 .

6. The epoxy silane resin cured reaction product of claim 5 , wherein the epoxy silane resin cured product is adhered to a casing disposed in the subterranean formation.

7. The curable composition of claim 1 , wherein an epoxy silane resin reaction product of the curable composition is effective for adhering to a casing disposed in the subterranean formation, thereby cementing or plugging the subterranean formation.

8. The curable composition of claim 1 , wherein the carrier fluid comprises water including at least one of fresh water, brine, produced water, flowback water, brackish water, and sea water.

9. The curable composition of claim 1 , wherein the carrier fluid comprises crude oil, dipropylene glycol methyl ether, dipropylene glycol dimethyl ether, dimethyl formamide, diethylene glycol methyl ether, ethylene glycol butyl ether, diethylene glycol butyl ether, butylglycidyl ether, propylene carbonate, D-limonene, a C 2 -C 40 fatty acid C 1 -C 10 alkyl ester, tetrahydrofurfuryl methacrylate, tetrahydrofurfuryl acrylate, 2-butoxy ethanol, butyl acetate, butyl lactate, furfuryl acetate, dimethyl sulfoxide, dimethyl formamide, a petroleum distillation product of fraction mineral oil, a hydrocarbon oil, a hydrocarbon including an aromatic carbon-carbon bond, a hydrocarbon including an alpha olefin, xylenes, an ionic liquid, methyl ethyl ketone, an ester of oxalic, maleic or succinic acid, methanol, ethanol, propanol, butyl alcohol, an aliphatic hydrocarbon, or a combination thereof.

10. The curable composition of claim 1 , wherein an epoxy silane resin reaction product of the curable composition comprises reduced or eliminated segregation of epoxy and silane domains, increasing homogeneity and temperature stability of the epoxy silane resin reaction product.

11. The curable composition of claim 1 , wherein an epoxy silane resin reaction product of the curable composition comprises a degradation onset between about 300° F. and about 800° F.
