METHODS OF CEMENTING IN SUBTERRANEAN FORMATIONS USING CEMENT KILN DUST IN COMPOSITIONS HAVING REDUCED PORTLAND CEMENT CONTENT.

摘要

The present invention includes methods of cementing in subterranean formations using cement kiln dust in compositions having reduced Portland cement content. An embodiment of a method comprises placing a sealant composition that comprises cement kiln dust and is essentially free of Portland cement in a subterranean formation; and allowing the sealant composition to set.
