Abstract

Various embodiments disclosed relate to compatibilized resin-cement composite compositions and methods of using the same. In various embodiments, the present invention provides a method of treating a subterranean formation that includes placing in the subterranean formation a resin-cement composite composition. The resin-cement composite composition includes a resin, a cement, and a substituted or unsubstituted poly(alkylamine) compatibilizer.

First claim

What is claimed is:

1. A method of treating a subterranean formation, comprising:
placing a resin-cement compatibilized composite composition into a subterranean formation, wherein the composition comprises:
about 20 wt % to about 80 wt % of a curable epoxide resin;
about 20 wt % to about 80 wt % of a cement; and
about 1 wt % to about 15 wt % of a polyethyleneimine compatibilizer, wherein the polyethyleneimine compatibilizer binds to both the resin and the cement to avoid or resist phase separation of the resin and the cement and form a stable composition, and the polyethyleneimine has the following structure:

wherein:
at each occurrence, R 1 is selected from the group consisting of −H and a substituted or unsubstituted (C 1 -C 30 ) hydrocarbyl,

at each occurence, R 2 is a substituted or unsubstituted C 1 -C 30 )hydrocarbylene,
at each occurence, R 3 is selected from the group consisting of −H, a substituted or unsubstituted (C 1 -C 30 ) hydrocarbyl, and a substituted or unsubstituted (C 1 -C 30 )hydrocarbylene terminated with −NR 1 2 , and m1 is about 0 to about 100,000;
wherein the composition retains advantageous qualities of the resin used alone.

2. The method of claim 1 , further comprising mixing the resin, the cement, and the polyethyleneimine compatibilizer together to form the resin-cement composite composition at least partially above-surface.

3. The method of claim 1 , further comprising mixing the resin, the cement, and the polyethyleneimine compatibilizer together to form the resin-cement composite composition at least partially in the subterranean formation.

4. The method of claim 1 , wherein the method comprises at least one of cementing and repairing a wellbore in the subterranean formation.

5. The method of claim 1 , wherein the method comprises consolidating the subterranean formation.

6. The method of claim 1 , wherein the method comprises fracturing the subterranean formation.

7. The method of claim 1 , further comprising curing the resin-cement composite to provide a cured product of the resin-cement composite.

8. The method of claim 7 , wherein curing further comprises at least partially curing before the placing of the resin-cement composite composition in the subterranean formation.

9. The method of claim 7 , wherein curing further comprises at least partially curing in the subterranean formation.

10. The method of claim 7 , wherein the cured product has a tensile strength of about 115 psi to about 10,000 psi.

11. The method of claim 7 , wherein the cured product has a tensile strength of about 200 psi to about 800 psi.

12. The method of claim 7 , wherein the cured product has a compressive strength of about 300 psi to about 10,000 psi.

13. The method of claim 7 , wherein the cured product has a compressive strength of about 1,000 psi to about 3,000 psi.

14. The method of claim 1 , wherein the resin-cement composite composition is sufficient to be a stable homogenous mixture without mixing or agitation for at least 1 day.

15. The method of claim 1 , wherein the placing of the resin-cement composite composition in the subterranean formation comprises pumping the resin-cement composite composition through a tubular disposed in a wellbore and into the subterranean formation.

16. The method of claim 1 , wherein the placing of the resin-cement composite composition in the subterranean formation comprises pumping the composition through a casing disposed in a wellbore and into an annulus between the casing and the wellbore.

17. A compatibilized resin-cement composite composition for treatment of a subterranean formation, comprising:
about 20 wt % to about 80 wt % of a curable epoxide resin;
about 20 wt % to about 80 w t% of a cement; and
about 1 wt % to about 15 wt % of a polyethyleneimine compatibilizer, wherein the polyethyleneimine compatibilizer is configured to bind to both the resin and the cement to avoid or resist phase separation of the cement and the resin such that the composition is stable, and the polyethyleneimine has the following structure:

wherein:
at each occurrence, R 1 is selected from the group consisting of −H and a substituted or unsubstituted (C 1 -C 30 )hydrocarbyl,
at each occurence, R 2 is a substituted or unsubstituted C 1 -C 30 )hydrocarbylene,
at each occurence, R 3 is selected from the group consisting of −H, a substituted or unsubstituted (C 1 -C 30 ) hydrocarbyl, and a substituted or unsubstituted (C 1 -C 30 )hydrocarbylene terminated with −NR 1 2 , and m1 is about 0 to about 100,000;

wherein the composition retains advantageous qualities of the resin used alone.

18. A cured product of the composition of claim 17 .

19. The composition of claim 17 , wherein the composition can be used in a greater variety of wellbore conditions than a composition consisting essentially of the cement or a composition consisting essentially of the curable epoxide resin.
