Abstract
Embodiments relate to the use of alkali aluminates and alkali silicates with cement kiln dust to form a settable composition for use in subterranean operations. An embodiment provides a method comprising: introducing a settable composition comprising cement kiln dust, an alkali aluminate, an alkali silicate, and an aqueous carrier fluid into a subterranean formation; and allowing the settable composition to set and thereby reduce fluid flow through a portion of the subterranean formation.
Claims13
A method comprising:
- introducing a settable composition comprising cement kiln dust, an alkali aluminate, an alkali silicate, and an aqueous carrier fluid into a wellbore penetrating a subterranean formation, wherein introducing the settable composition comprises:
- introducing a first aqueous stream comprising the alkali aluminate through a first flow path;
- introducing a second aqueous stream comprising the alkali silicate through a second flow path;
- and
- contacting the first aqueous stream and the second aqueous stream to form the settable composition, wherein the first flow path and the second flow path are separate and wherein the cement kiln dust is present in the first aqueous fluid, the second aqueous fluid, or both;
- and
- allowing the settable composition to set and thereby reduce fluid flow through a portion of the subterranean formation.

A method comprising:
- introducing a first stream comprising an aqueous alkali aluminate and cement kiln dust into a lost circulation zone in a subterranean formation;
- introducing a second stream comprising an aqueous alkali silicate into the lost circulation zone in the subterranean formation;
- forming a settable composition upon intermixing of the first stream and the second stream;
- and
- allowing the settable composition to set in the lost circulation zone.
