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.

First claim

What is claimed is:

1. A method comprising:
drilling a wellbore in a subterranean formation using a bottom hole assembly attached to a tubular, wherein an annulus is defined between the tubular and walls of the wellbore; and
pumping a consolidating spacer fluid into the annulus through the bottom hole assembly, wherein the consolidating spacer fluid comprises a kiln dust and water; wherein the bottom hole assembly comprises a drill bit, wherein the consolidating spacer fluid is pumped through the drill bit, and wherein the consolidating spacer fluid is pumped into the wellbore between a drilling fluid and a cement composition.

2. The method of claim 1 , wherein the bottom hole assembly is retrievable.

3. The method of claim 1 , wherein the bottom hole assembly is non-retrievable.

4. The method of claim 1 , wherein the tubular is a drill pipe, a casing, or a combination thereof.

5. The method of claim 1 , wherein at least a portion of the wellbore extends at a direction that is slanted from vertical.

6. The method of claim 1 , further comprising circulating a drilling fluid in the wellbore while drilling the wellbore, wherein at least a portion of the drilling fluid is displaced from the wellbore by the consolidating spacer fluid.

7. The method of claim 1 , further comprising allowing at least a portion of the consolidating spacer fluid to consolidate in the wellbore to have a transition time of about 45 minutes or less.

8. The method of claim 1 , further comprising allowing at least a portion of the consolidating spacer fluid to consolidate in the wellbore to have 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 ft 2 to about 500 lbf/100 ft 2 , (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.

9. The method of claim 1 , further comprising allowing at least a portion of the consolidating spacer fluid to consolidate in the wellbore to have 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 ft 2 in a time of from about 10 minutes to about 8 hours.

10. The method of claim 1 , further comprising allowing at least a portion of the consolidating spacer fluid to consolidate in the wellbore and running a bond log to determine bonding of the consolidating treatment fluid to the casing.

11. The method of claim 1 , wherein the consolidating spacer fluid has a density of about 4 pounds per gallon to about 13 pounds per gallon.

12. The method of claim 1 , wherein the kiln dust is from the manufacture of cement.

13. The method of claim 1 , wherein the kiln dust comprises SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, Na2O, and K2O.

14. The method of claim 1 , wherein the kiln dust is present in an amount from about 1% to about 65% by weight of the consolidating spacer fluid.
