Abstract

Disclosed are spacer fluids and methods of use in subterranean formations. Embodiments may include use of consolidating spacer fluids in displacement of drilling fluids from a well bore annulus.

Claims

1. A method of evaluating a spacer fluid for use in separating a drilling fluid and a cement composition in a well bore comprising:

providing the spacer fluid, wherein the spacer fluid comprises kiln dust; and

measuring a transition time and/or zero gel time of the spacer fluid.

2. The method of claim 1 wherein the transition time of the spacer fluid is about 45 minutes or less at well bore conditions.

3. The method of claim 1 wherein the transition time of the spacer fluid is about 20 minutes or less at a temperature in a range of from about 40°

F. to about 300°

F. and a pressure in a range of from about 2,000 psi to about 10,000 psi.

4. The method of claim 1 further comprising measuring a compressive strength of the spacer fluid.

5. The method of claim 1 further comprising:

providing a cement composition, measuring a transition time of the cement composition, and comparing the transition time of the cement composition and the transition time of the spacer fluid, wherein the transition time of the spacer fluid is shorter than the transition time of the cement composition.

6. The method of claim 1 wherein the zero gel time of the spacer fluid is about 4 hours or less at well bore conditions.

7. The method of claim 1 further comprising:

providing a cement composition, measuring a zero gel time of the cement composition, and comparing the zero gel time of the cement composition and the zero gel time of the spacer fluid.

8. The method of claim 1 wherein the zero gel time of the spacer fluid is longer than the zero time of the cement composition.

9. The method of claim 1 wherein the spacer fluid is foamed and has a density in a range of from about 4 pounds per gallon to about 13 pounds per gallon.

10. The method of claim 1 wherein the kiln dust is selected from the group consisting of cement kiln dust, lime kiln dust, and combinations thereof.

11. The method of claim 1 wherein the spacer fluid comprises kiln dust in an amount in a range of from about 1% to about 60% by weight of the spacer fluid.

12. The method of claim 1 wherein the spacer fluid comprises at least one additive selected from the group consisting of a free water control additive, a lightweight additive, a foaming agent, a supplementary cementitious material, a weighting agent of any suitable size, a viscosifying agent, a fluid loss control agent, a lost circulation material, a filtration control additive, a dispersant, a defoamer, a corrosion inhibitor, a scale inhibitor, a formation conditioning agent, a water-wetting surfactant, and any combination thereof.

15. The method of claim 1 further comprising pumping the spacer fluid into the wellbore using a pump.

16. A method of evaluating a plurality of spacer fluids for use in separating a drilling fluid and a cement composition in a well bore comprising:

providing the plurality of spacer fluids;

measuring a transition time, zero gel time and/or compressive strength of each of the spacer fluids;

selecting one spacer fluid from the plurality of spacer fluids, wherein the selected one of the spacer fluids comprises at least one kiln dust selected from the group consisting of cement kiln dust and lime kiln dust; and

using the selected spacer fluid to separate the drilling fluid and a cement composition in a well bore.

17. The method of claim 16 wherein the transition time of the selected one of the spacer fluids is about 45 minutes or less at well bore conditions.

18. The method of claim 16 wherein the transition time of the selected one of the spacer fluids is about 20 minutes or less at a temperature in a range of from about 40°

F. to about 300°

F. and a pressure in a range of from about 2,000 psi to about 10,000 psi.

19. The method of claim 16 wherein the zero gel time of the selected one of the spacer fluids is about 4 hours or less at well bore conditions.

20. The method of claim 16 wherein at least one of the spacer fluids comprises at least one cementitious material selected from the group consisting of Portland cement, Portland cement interground with pumice, micro-fine cement, slag, fly ash, rice husk ash, pumicite, gypsum, and any combination thereof.
