Low carbon footprint expansive composition and methods of making and using same
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.
1. A composition comprising (i) a blend comprising a cementitious material, a pozzolanic material, aplite, and (ii) an aqueous fluid, wherein the composition has a positive expansion upon setting,
wherein the cementitious material comprises a Portland cement,
wherein the pozzolanic material comprises Trass flour, pumice, calcined clay, ground granulated blast furnace slag, fly ash, or bentonite, and
wherein the aplite is present in the composition in an amount from about 15% by weight of the blend (BWOB) to about 35% BWOB.
2. The composition of claim 1 , wherein the aplite comprises granite and the pozzolanic material comprises Trass flour.
3. The composition of claim 2 , wherein the blend further comprises silica fume.
4. The composition of claim 3 , further comprising a sodium chloride and sodium sulfate blend.
5. The composition of claim 2 , further comprising a sodium chloride and sodium sulfate blend.
6. The composition of claim 1 , wherein the aplite comprises granite and the pozzolanic material comprises pumice.
7. The composition of claim 6 , wherein the blend further comprises silica fume.
8. The composition of claim 7 , further comprising a sodium chloride and sodium sulfate blend.
9. The composition of claim 1 , wherein the aplite comprises granite and the pozzolanic material comprises calcined clay.
10. The composition of claim 1 , wherein the aplite comprises granite and the pozzolanic material comprises ground granulated blast furnace slag.
11. The composition of claim 1 , wherein the aplite comprises granite and the pozzolanic material comprises fly ash.
12. The composition of claim 1 , wherein the aplite comprises granite and the pozzolanic material comprises bentonite.
13. The composition of claim 1 , wherein the blend further comprises silica fume.
14. The composition of claim 1 , further comprising a sodium chloride and sodium sulfate blend.
15. The composition of claim 1 , further comprising a sodium chloride and sodium sulfate blend.
16. 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.
17. A composition comprising (i) a blend comprising a cementitious material, a pozzolanic material, aplite, and (ii) an aqueous fluid, wherein the composition has a positive expansion upon setting,
wherein the cementitious material comprises a Portland cement,
wherein the pozzolanic material comprises Trass flour, pumice, calcined clay, ground granulated blast furnace, fly ash, or bentonite, and
wherein the aplite is present in the composition in an amount from about 15% BWOB to about 35% BWOB.
18. The composition of claim 17 , wherein the composition further comprises silica fume.
19. The composition of claim 18 , wherein the composition further comprises a sodium chloride and sodium sulfate blend.
20. The composition of claim 19 , wherein the pozzolanic material comprises Trass flour.
21. The composition of claim 18 , wherein the pozzolanic material comprises Trass flour.
22. The composition of claim 18 , wherein the pozzolanic material comprises fly ash.
23. The composition of claim 17 , wherein the composition further comprises a sodium chloride and sodium sulfate blend.
24. A method of servicing a wellbore penetrating a subterranean formation, comprising:
placing a composition of claim 17 into the wellbore; and
allowing the composition to form a set cement.
