Abstract

Various embodiments disclosed relate to compositions including a glycerol ester including at least two epoxides for treatment of subterranean formations. In various embodiments, the present invention provides a method of treating a subterranean formation. The method includes placing in a subterranean formation a composition including a glycerol ester that includes at least two epoxides. The composition also includes a hardening agent.

First claim

What is claimed is:

1. A method for treating a subterranean formation, comprising:
placing a composition into the subterranean formation, the composition consists essentially of:
a glycerol ester comprising at least two epoxides; and
a hardening agent.

2. The method of claim 1 , further comprising consolidating particulates in the subterranean formation with a cured product of the composition.

3. The method of claim 1 , wherein the composition is at least partially coated on at least one of proppant, gravel, or a combination thereof, and wherein the proppant or gravel is about 5 wt % to about 70 wt % of the composition.

4. The method of claim 3 , further comprising:
forming a fracture in the subterranean formation; and
placing the composition and the proppant or gravel in the fracture.

5. The method of claim 1 , wherein the hardening agent is about 0.01 wt % to about 30 wt % of the composition.

6. The method of claim 1 , wherein the glycerol ester comprising at least two epoxides has an epoxide equivalent weight of about 100 g/mol to about 500 g/mol.

7. The method of claim 1 , wherein the glycerol ester comprises a fatty acid glycerol ester.

8. The method of claim 1 , wherein the glycerol ester comprising at least two epoxides has the following structure:

wherein:
each R 1 , R 2 , and R 3 is independently selected from the group consisting of —H, substituted or unsubstituted (C 1 -C 60 )hydrocarbyl, and R 4 ,
wherein:
R 4 at each occurrence is independently —C(O)—(C 2 -C 60 )hydrocarbyl comprising at least two oxygen atoms each independently directly attached to two different adjacent carbon atoms of the (C 2 -C 60 )hydrocarbyl,
the (C 1 -C 60 )hydrocarbyl and the (C 2 -C 60 )hydrocarbyl are independently interrupted by 0, 1, 2, or 3 groups independently chosen from —O—, —S—, and substituted or unsubstituted —NH—, and
at least one of R 1 , R 2 , and R 3 is R 4 .

9. The method of claim 8 , wherein each of R 1 , R 2 , and R 3 are independently selected from R 4 and —H.

10. The method of claim 8 , wherein at least two of R 1 , R 2 , and R 3 are R 4 .

11. The method of claim 8 , wherein each of R 1 , R 2 , and R 3 is R 4 .

12. The method of claim 8 , wherein:
R 1 , R 2 , and R 3 are independently chosen from —H, substituted or unsubstituted (C 5 -C 60 )alkyl, substituted or unsubstituted —C(O)—(C 4 -C 59 )alkyl substituted or unsubstituted (C 5 -C 60 )alkenyl, substituted or unsubstituted —C(O)—(C 4 -C 59 )alkenyl, and R 4 ,
the (C 5 -C 60 )alkenyl and the —C(O)—(C 4 -C 59 )alkenyl each independently comprise about 1 to about 29 carbon-carbon double bonds, and
the (C 5 -C 60 )alkyl, the —C(O)—(C 4 -C 59 )alkyl, the (C 5 -C 60 )alkenyl, and the —C(O)—(C 4 -C 59 )alkenyl each independently comprise about 2 to about 30 oxygen atoms each independently directly bound to two different adjacent carbon atoms of the (C 5 -C 60 )alkyl, the —C(O)—(C 4 -C 59 )alkyl, the (C 5 -C 60 )alkenyl, and the —C(O)—(C 4 -C 59 )alkenyl.

13. The method of claim 8 , wherein:
R 4 at each occurrence is independently chosen from —C(O)—(C 2 -C 60 )alkyl and —C(O)—(C 2 -C 60 )alkenyl, and
the (C 2 -C 60 )alkyl and the (C 2 -C 60 )alkenyl each independently comprise about 2 to about 30 oxygen atoms each independently directly bound to two different adjacent carbon atoms of the —C(O)—(C 2 -C 60 )alkyl and —C(O)—(C 2 -C 60 )alkenyl.

14. The method of claim 1 , wherein the glycerol ester comprising at least two epoxides is an at least partially epoxidized oil chosen from soybean oil and linseed oil.

15. The method of claim 1 , wherein the glycerol ester comprising at least two epoxides comprises:

16. The method of claim 1 , wherein the glycerol ester comprising at least two epoxides comprises:

17. The method of claim 1 , wherein the hardening agent is selected from the group consisting of diethylene tetramine, ethylene diamine, polyethyleneimine, piperidine, triethylamine, benzyldimethylamine, N,N-dimethylaminopyridine, 2-(N,N-dimethylaminomethyl)phenol, tris(dimethylaminomethyl)phenol, N-2-(aminoethyl)-3-aminopropyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, n-beta-(aminoethyl)-gamma-aminopropyl trimethoxysilane, piperazine, aminoethylpiperazine, pyrrole, imidazole, pyrazole, pyridine, pyrazine, pyrimidine, pyridazine, indolizine, isoindole, indole, indazole, purine, quinolizine, quinoline, isoquinoline, phthalazine, naphthyridine, quinoxaline, quinazoline, carbazole, carbazole, phenanthridine, acridine, phenathroline, phenazine, imidazolidine, phenoxazine, cinnoline, pyrrolidine, pyrroline, imidazoline, piperidine, indoline, isoindoline, quinuclindine, morpholine, azocine, azepine, azepine, 1,3,5-triazine, thiazole, pteridine, dihydroquinoline, hexamethyleneimine, indazole, polyethyleneimine, 2-ethyl-4-methyl imidazole, 1,1,3-trichlorotrifluoroacetone, and any combination thereof.
