Abstract
The present invention provides settable compositions that comprise water and cement kiln dust. The settable compositions optionally may comprise an additive that comprises at least one of the following group: fly ash; shale; slag cement; zeolite; metakaolin; and combinations thereof. The settable compositions optionally may be foamed with a gas. Methods of cementing also are provided that comprise: providing the settable composition; introducing the settable composition into a location to be cemented; and allowing the settable composition to set therein. The location to be cemented may be above ground or in a subterranean formation.
Claims27
A method comprising:
- providing a settable composition comprising water and cement kiln dust;
- introducing the settable composition into a subterranean formation;
- and
- allowing the settable composition to set in a portion of an annulus between the subterranean formation and a pipe string disposed in the subterranean formation.
A method of cementing a pipe string disposed in a subterranean formation comprising:
- providing a settable composition comprising water and cement kiln dust;
- introducing the settable composition into an annulus between the pipe string and the subterranean formation;
- and
- allowing the settable composition to set in the annulus to form a hardened mass.
A method of cementing comprising:
- providing a settable composition comprising water, cement kiln dust in an amount in the range of from about 5% to 100% by weight, and a hydraulic cement;
- introducing the settable composition into a subterranean formation;
- and
- allowing the settable composition to set in a portion of an annulus between the subterranean formation and a pipe string disposed in the subterranean formation.
