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.
Claims23
A method of cementing comprising:
- providing a foamed settable composition comprising water, cement kiln dust, a gas, and a surfactant;
- introducing the foamed settable composition into a location to be cemented;
- and
- allowing the foamed settable composition to form a hardened mass therein.
A method of cementing a pipe string disposed in a well bore comprising:
- providing a foamed settable composition comprising water, cement kiln dust, a gas, and a surfactant;
- introducing the foamed settable composition into an annulus between the pipe string and a wall of the well bore;
- and
- allowing the foamed settable composition to set in the annulus.
A method of cementing comprising:
- providing a settable composition comprising water, cement kiln dust, and a surfactant;
- foaming the settable composition with a gas to form a foamed settable composition;
- introducing the foamed settable composition into a location to be cemented;
- and
- allowing the foamed settable composition to set therein.
