Tunable Control of Pozzolan-Lime Cement Compositions
First Claim
1. A method of formulating a cement composition:
- measuring surface area of a group of pozzolans, wherein the smallest measured surface area of the group of pozzolans and the largest measured surface area of the group of pozzolans vary by about 50% or greater;
selecting one or more pozzolans from the group of pozzolans;
adding components comprising lime and water to the selected one or more pozzolans to form a cement composition.

11. A method of cementing in a subterranean formation comprising:
-
providing a first pozzolan; providing a second pozzolan, wherein the second pozzolan comprises pozzolan particles having a surface area that varies by about 50% or more from pozzolan particles of the first pozzolan; blending the first pozzolan and the second pozzolan to form a blended pozzolan; adding components comprising lime and water to the blended pozzolan to form a cement composition; introducing the cement composition into the subterranean formation; and allowing the cement composition to set in the subterranean formation. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A system for cementing in a subterranean formation comprising:
-
a first pozzolan, a second pozzolan;
wherein the second pozzolan comprises pozzolan particles having a surface area that varies by about 50% or more from pozzolan particles of the first pozzolan,lime, and water; mixing equipment capable of mixing the first pozzolan, the second pozzolan, the lime, and the water; and pumping equipment capable of pumping the cement composition formed by mixing the first pozzolan, the second pozzolan, the lime, and the water. - View Dependent Claims (22, 23)
