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.
1. A drilling system comprising: a bottom hole assembly comprising a drill bit;a cement composition;a drilling fluid; anda 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 c
1. A drilling system comprising: a bottom hole assembly comprising a drill bit;a cement composition;a drilling fluid; anda 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. 2. The system of claim 1, further comprising a tubular, wherein the bottom hole assembly is attached to the tubular. 3. The system of claim 2, wherein the tubular is a drill pipe, a casing, or a combination thereof. 4. The system of claim 1, wherein the bottom hole assembly is retrievable. 5. The system of claim 1, wherein the bottom hole assembly is non-retrievable. 6. The system of claim 1, wherein at least a portion of the wellbore extends at a direction that is slanted from vertical. 7. The system of claim 1, wherein the consolidating fluid has a transition time of about 45 minutes or less. 8. The system of claim 1, wherein the consolidating spacer fluid has a density of about 4 pounds per gallon to about 13 pounds per gallon. 9. The system of claim 1, wherein the kiln dust is from the manufacture of cement. 10. The system of claim 1, wherein the kiln dust comprises SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, Na2O, and K2O. 11. The system of claim 1, wherein the kiln dust may be present in the consolidating spacer fluid in an amount of about 1% to about 65% by weight of the consolidating spacer fluid. 12. The system of claim 1 wherein the consolidating spacer fluid is capable of displacing at least a portion of the drilling fluid from the wellbore. 13. A drilling system comprising: a bottom hole assembly comprising a drill bit;a drilling fluid;a cement composition; anda consolidated spacer fluid for introduction into a wellbore through the drill bit between the drilling fluid and the cement composition, wherein the consolidated spacer fluid comprises a kiln dust and water, wherein the consolidated spacer fluid has at least one property selected from the group consisting of: (i) a yield point of from about 25 Pascals to about 250 pascals; (ii) a static gel strength of from about 70 lbf/100 ft2 to about 500 lbf/100 ft2, (iii) a yield limit in compression from about 1 psi to about 2,000 psi, and (iv) an unconfined uniaxial compressive strength of from about 5 psi to about 10,000 psi. 14. The system of claim 13, wherein the consolidated spacer fluid further has at least one property selected from the group consisting of: (i) a zero gel time of about 8 hours or less, (ii) a transition time of about 45 minutes or less, and (iii) a static gel strength of about 500 lbf/100 ft2 in a time of from about 10 minutes to about 8 hours. 15. The system of claim 13, wherein the kiln dust is from the manufacture of cement. 16. The system of claim 13, further comprising a bond log capable for measuring the degree of bonding of the consolidated spacer fluid to a casing in the well bore.
