Abstract

A compatibilized cement composition for the treatment of a subterranean formation and a method of treating a subterranean formation are disclosed. The method can include placing in a subterranean formation a composition including a compatibilized cement composition. The compatibilized cement composition can include a curable resin or cured product thereof, a cement slurry, and a compatibilizer composition, a reaction product thereof, or a combination thereof. The compatibilizer composition can include a substituted or unsubstituted C5-C50 hydrocarbon including at least one internal olefin and a polyether.

First claim

What is claimed is:

1. A method of treating a subterranean formation, comprising:
placing a composition comprising a compatibilized cement composition into the subterranean formation, the compatibilized cement composition comprising:
a curable resin or a cured product thereof comprising an epoxy resin and an amine hardener;
a cement slurry; and
a compatibilizer composition, a reaction product thereof, or a combination thereof, the compatibilizer composition comprising:
a substituted or unsubstituted C 5 -C 50 hydrocarbon including at least one internal olefin, and
a polyether.

2. The method of claim 1 , wherein the epoxy resin is about 50 wt % to about 99 wt % of the curable resin or cured product thereof, and wherein the epoxy resin is chosen from diglycidyl ether bisphenol A resin, butyl glycidyl ether, cyclohexane methanol diglycidyl ether, and combinations thereof.

3. The method of claim 1 , wherein the amine hardener is about 1 wt % to about 50 wt % of the curable resin, and wherein the amine hardener is selected from the group consisting of diethyl toluene diamine; 2,4,6-tris(dimethylaminomethyl)phenol; bis(methylthio)-toluene diamine; and any combination thereof.

4. The method of claim 1 , wherein the cement slurry comprises a cement and water, wherein the cement is selected from the group consisting of Portland cement, pozzolana cement, gypsum cement, high alumina content cement, slag cement, silica cement, pumice, perlite, and any combination thereof, and wherein the water is about 30% to about 60% by weight of cement.

5. The method of claim 1 , wherein the cement slurry comprises a cement, water, and a thickener, wherein the thickener is about 0.01% to about 2.0% by weight of cement, and wherein the thickener comprises hydroxyl ethyl cellulose.

6. The method of claim 1 , wherein the compatibilizer composition is about 0.01% to about 1% by weight of water.

7. The method of claim 1 , wherein the substituted or unsubstituted C 5 -C 50 hydrocarbon with at least one internal olefin is a C 15 -C 18 alkene with at least one internal olefin, and is about 50 wt % to about 70 wt % of the compatibilizer composition.

8. The method of claim 1 , wherein the polyether is about 25 wt % to about 35 wt % of the compatibilizer composition.

9. The method of claim 1 , wherein the polyether has the structure:
R 1 O R 2 —O n R 2 —OR 1 ,

wherein:
at each occurrence R 1 is independently chosen from —H, —CH 3 , and —CH 2 CH 3 ,
at each occurrence R 2 is independently a substituted or unsubstituted (C 1 -C 5 ) hydrocarbylene, and
n is an integer chosen such that the polyether has an M n of 100 to 10,000.

10. The method of claim 9 , wherein R 1 is —H, and at each occurrence R 2 is independently chosen from —CH(CH 3 )CH 2 — and —CH 2 CH 2 —.

11. The method of claim 9 , wherein the polyether has the structure

wherein n is about 40 to about 100.

12. The method of claim 1 , wherein the compatibilizer composition further comprises a silica, wherein the silica is about 8 wt % to about 12 wt % of the compatibilizer composition, and wherein the silica comprises a silane-treated silica.

13. The method of claim 12 , wherein the silane-treated silica comprises a poly(dimethylsiloxane)-treated silica.

14. The method of claim 1 , wherein the compatibilizer composition further comprises a stabilizer, wherein the stabilizer is about 1.0 wt % to about 2.0 wt % of the compatibilizer composition, and wherein the stabilizer is selected from the group consisting of hydroquinone, catechol, hydroquinone monomethyl ether, an alkyl gallate, a hindered phenol, and any combination thereof.

15. The method of claim 14 , wherein the stabilizer comprises a hindered phenol, and wherein the hindered phenol is selected from the group consisting of butylated hydroxyanisol; 4-ethoxyphenol; butylated hydroxytoluene, 4-methoxyphenol; 3-methoxyphenol; 2-tertbutyl-4methoxyphenol; 2-tert-butyl-4-methoxyphenol; 2,2-methylene-bis-(4-methyl-6-tert-butylphenol); and any combination thereof.

16. The method of claim 1 , wherein the compatibilizer composition further comprises a fatty alcohol ethoxylate.

17. A system for performing the method of claim 1 , the system comprising:
a tubular disposed in the subterranean formation; and
a pump configured to pump the composition into the subterranean formation through the tubular.

18. A method of treating a subterranean formation, comprising:
placing a composition comprising a compatibilized cement composition into a subterranean formation, the compatibilized cement composition comprising:
a curable resin or cured product thereof comprising diglycidyl ether bisphenol A resin, butyl glycidyl ether, cyclohexane methanol diglycidyl ether, diethyl toluene diamine, and 2,4,6-tris(dimethylaminomethyl)phenol, wherein the curable resin or cured product thereof is about 1% to about 50% by volume of the compatibilized cement composition;
a cement slurry comprising a class G cement, water, and hydroxyl ethyl cellulose, wherein the cement slurry is about 50% to about 99% by volume of the compatibilized cement composition; and
a compatibilizer composition, a reaction product thereof, or a combination thereof, the compatibilizer composition comprising:
a C 15 -C 18 alkene with at least one internal olefin,
a polyether having the structure:

wherein n is about 40 to about 100,
wherein the compatibilizer composition is about 0.01% to about 5.0% by weight of water.
