Abstract
Embodiments relate to systems and methods for introduction of fluids comprising kiln dust into a wellbore through a bottom hole assembly. An embodiment discloses a method comprising: drilling a wellbore in a subterranean formation using a bottom hole assembly; and pumping a treatment fluid into the wellbore through the bottom hole assembly, wherein the treatment fluid comprises a kiln dust and water.
Claims16
A drilling system comprising:
- a bottom hole assembly comprising a drill bit;
- a cement composition;
- a drilling fluid;
- and
- a consolidating spacer fluid for introduction into a wellbore through the drill bit between the drilling fluid and the cement composition, wherein the consolidating spacer fluid comprises a kiln dust and water.
