Abstract
A variety of systems, methods and compositions are disclosed for cementing in subterranean formations. Embodiments may include the use of slag co-grind in well cementing operations.
Claims14
A method of cementing comprising:
- first, co-grinding a composition consisting of slag and at least one cement component selected from the group consisting of metakaolin, shale, perlite, pozzolan, zeolite, calcium aluminate cement, and combinations thereof, to form a slag co-grind, wherein the slag is a by-product from processing of a metal ore;
- second, dry blending the slag co-grind and a cement to form a cement dry blend;
- thereafter, preparing a cement composition comprising water and the cement dry blend and introducing the cement composition into a subterranean formation;
- and
- allowing the cement composition to set in the subterranean formation.

A system for cementing in a subterranean formation comprising:
- a cement composition comprising a cement, water, and a slag co-grind, wherein the slag co-grind consists of slag and at least one cement component selected from the group consisting of metakaolin, shale, perlite, pozzolan, zeolite, calcium aluminate cement, and combinations thereof ground together, wherein the slag is a by-product from processing of a metal ore;
- mixing equipment capable of mixing the cement composition;
- and
- pumping equipment capable of delivering the cement composition into a wellbore.
