Abstract

Disclosed herein is a composition comprising a cementitious material, a pozzolanic material, aplite, and an aqueous fluid. Also disclosed herein is a method of servicing a wellbore penetrating a subterranean formation, comprising: placing the composition into the wellbore; and allowing the composition to form a set cement. The composition can develop suitable mechanical properties and permeability after setting in a wellbore and be expansive.

First claim

What is claimed is:

1. A composition comprising (i) a blend of Portland cement and Trass flour and (ii) an aqueous fluid,
wherein the Trass flour is present in the composition in an amount from about 40% by weight of the blend (BWOB) to about 70% BWOB,
wherein the composition has a positive expansion upon setting,
wherein the Portland cement is present in the composition in an amount from about 30 to about 60% BWOB, and
wherein the composition has a 14-day circumferential change in a range of from about 0.01% to about 2% at a temperature in a range of from about 20° C./68° F. to about 150° C./302° F., when measured in a ring expansion test in accordance with test standard API 10B-5.

2. The composition of claim 1 , wherein the blend further comprises aplite.

3. The composition of claim 2 , wherein the aplite is present in the composition in an amount from about 10% by weight of the blend (BWOB) to about 60% BWOB.

4. The composition of claim 2 , wherein the aplite is present in the composition in an amount from about 10 to about 40% BWOB.

5. The composition of claim 2 , further comprising fly ash.

6. The composition of claim 2 , wherein the aplite comprises fine-grained particles of less than or equal to about 2 millimeters.

7. The composition of claim 1 , further comprising silica fume.

8. The composition of claim 1 , further comprising a sodium chloride and sodium sulfate blend.

9. A method of servicing a wellbore penetrating a subterranean formation, comprising:
placing a composition of claim 1 into the wellbore; and
allowing the composition to form a set cement.

10. The composition of claim 1 , wherein the Trass flour has a d50 particle size distribution of equal to or less than about 50 microns.

11. The composition of claim 1 , further comprising fly ash.

12. The composition of claim 1 , wherein the Trass flour is present in the composition in an amount from about 45% by weight of the blend (BWOB) to about 70% BWOB and wherein the Portland cement is present in the composition in an amount from about 30 to about 55% BWOB.

13. The composition of claim 1 , wherein the Trass flour is present in the composition in an amount from about 50% by weight of the blend (BWOB) to about 70% BWOB and wherein the Portland cement is present in the composition in an amount from about 30 to about 50% BWOB.

14. A composition comprising (i) a blend of Portland cement and fly ash and (ii) an aqueous fluid,
wherein the fly ash is present in the composition in an amount from about 40% by weight of the blend (BWOB) to about 70% BWOB,
wherein the composition has a positive expansion upon setting,
wherein the Portland cement is present in the composition in an amount from about 30 to about 60% BWOB, and
wherein the composition has a 14-day circumferential change in a range of from about 0.01% to about 2% at a temperature in a range of from about 20° C./68° F. to about 150° C./302° F., when measured in a ring expansion test in accordance with test standard API 10B-5.

15. The composition of claim 14 , wherein the blend further comprises aplite.

16. The composition of claim 15 , wherein the aplite is present in the composition in an amount from about 10% by weight of the blend (BWOB) to about 60% BWOB.

17. The composition of claim 15 , wherein the aplite is present in the composition in an amount from about 10 to about 40% BWOB.

18. The composition of claim 15 , wherein the aplite comprises fine-grained particles of less than or equal to about 2 millimeters.

19. The composition of claim 14 , further comprising silica fume.

20. The composition of claim 14 , further comprising a sodium chloride and sodium sulfate blend.

21. A method of servicing a wellbore penetrating a subterranean formation, comprising:
placing a composition of claim 8 into the wellbore; and
allowing the composition to form a set cement.

22. The composition of claim 14 , wherein the fly ash is present in the composition in an amount from about 45% by weight of the blend (BWOB) to about 70% BWOB and wherein the Portland cement is present in the composition in an amount from about 30 to about 55% BWOB.

23. The composition of claim 14 , wherein the fly ash is present in the composition in an amount from about 50% by weight of the blend (BWOB) to about 70% BWOB and wherein the Portland cement is present in the composition in an amount from about 30 to about 50% BWOB.

24. A composition comprising (i) a blend of Portland cement and aplite and (ii) an aqueous fluid,
wherein the aplite is present in the composition in an amount from about 40% by weight of the blend (BWOB) to about 70% BWOB,
wherein the composition has a positive expansion upon setting,
wherein the Portland cement is present in the composition in an amount from about 30 to about 60% BWOB, and
wherein the composition has a 14-day circumferential change in a range of from about 0.01% to about 2% at a temperature in a range of from about 20° C./68° F. to about 150° C./302° F., when measured in a ring expansion test in accordance with test standard API 10B-5.

25. The composition of claim 24 , further comprising silica fume.

26. The composition of claim 24 , further comprising a sodium chloride and sodium sulfate blend.

27. A method of servicing a wellbore penetrating a subterranean formation, comprising:
placing a composition of claim 24 into the wellbore; and
allowing the composition to form a set cement.
