Abstract

Disclosed are spacer fluids and methods of use in subterranean formations. Embodiments may include use of solid surfactant composites in well cementing operations.

First claim

What is claimed is:

1. A composition comprising:
a solid surfactant composite comprising a water-wetting surfactant and a solid carrier; wherein the solid carrier comprises amorphous silica and the solid surfactant composite further comprises a naphthalene sulfonate formaldehyde condensate and a polydimethyl siloxane; and
a solid particulate additive dry blended with the solid surfactant composite.

2. The composition of claim 1 , wherein the solid surfactant composite is spray dried.

3. The composition of claim 1 , wherein the solid surfactant composite further comprise at least one additive selected from the group consisting of a dispersant, a defoaming agent, and any combination thereof.

4. The composition of claim 1 , wherein the solid surfactant composite may be added to the spacer fluid in an amount in a range of from about 0.1% to about 20% by weight of the spacer fluid.

5. The composition of claim 1 , wherein the water-wetting surfactant comprises at least one surfactant selected from the group consisting of an alcohol ethoxylate, an alcohol ethoxysulfate, an alkyl phenol ethoxylate, a glycol ether, and any combination thereof.

6. The composition of claim 1 , wherein the water-wetting surfactant comprises an alcohol ethoxylate, wherein the alcohol ethoxylate comprises C8 to C12 alcohol ethoxylated with about 4 moles to about 8 moles of ethylene oxide.

7. The composition of claim 1 , wherein the water-wetting surfactant comprises an alcohol ethoxylate, wherein the alcohol ethoxylate comprises C12 to C14 alcohol ethoxylated with about 10 moles to about 14 moles of ethylene oxide.

8. The composition of claim 1 , wherein the water-wetting surfactant may be included in the solid surfactant composite in an amount, without limitation, of from about 5% to about 99.9% by weight of the solid surfactant composite.

9. The composition of claim 1 , wherein the solid carrier may be included in the solid surfactant composite in an amount, without limitation, of from about 0.1% to about 95% by weight of the solid surfactant composite.

10. The composition of claim 1 , wherein the solid particulate additive comprises at least one solid material selected from the group consisting of a weighting agent, vitrified shale, cement kiln dust, silica flour, bentonite, pumice, fly ash, hematite, hausmannite, barite, calcium carbonate, and any combination thereof.

11. A composition comprising:
a solid surfactant composite for use in a spacer fluid comprising a water-wetting surfactant and a solid carrier, wherein the water-wetting surfactant comprises an alcohol ethoxylate, wherein the alcohol ethoxylate comprises C12 to C14 alcohol ethoxylated with about 10 moles to about 14 moles of ethylene oxide, and wherein the solid carrier comprises amorphous silica, and wherein the solid surfactant composite further comprises a naphthalene sulfonate formaldehyde condensate and a polydimethyl siloxane; and
a solid particulate additive dry blended with the solid surfactant composite.

12. The composition of claim 11 , wherein the solid surfactant composite further comprises at least one additive selected from the group consisting of a dispersant, a defoaming agent, and any combination thereof.

13. The composition of claim 11 , wherein the solid particulate additive comprises at least one solid material selected from the group consisting of a weighting agent, vitrified shale, cement kiln dust, silica flour, bentonite, pumice, fly ash, hematite, hausmannite, barite, calcium carbonate, and any combination thereof.

14. The composition of claim 11 , wherein the solid surfactant composite may be added to the spacer fluid in an amount in a range of from about 0.1% to about 20% by weight of the spacer fluid.

15. The composition of claim 11 , wherein the amorphous silica may be included in the solid surfactant composite in an amount about 0.45% by weight of the solid surfactant composite.

16. The composition of claim 11 , wherein the naphthalene sulfonate formaldehyde condensate may be included in the solid surfactant composite in an amount about 84.2% by weight of the solid surfactant composite.

17. The composition of claim 11 , wherein the polydimethyl siloxane may be included in the solid surfactant composite in an amount about 0.45% by weight of the solid surfactant composite.

18. A system comprising:
a solid surfactant composite for use in a spacer fluid, wherein the solid surfactant component comprises a water-wetting surfactant and a solid carrier, wherein the water-wetting surfactant comprises C12 to C14 alcohol ethoxylate ethoxylated with about 10 moles to about 14 moles of ethylene oxide, wherein the solid carrier comprises amorphous silica and diatomaceous earth, and wherein the solid surfactant composite further comprises a naphthalene sulfonate formaldehyde condensate and a polydimethyl siloxane;
a solid particulate additive dry blended with the solid surfactant composite;
a base fluid for use in the spacer fluid; and
a pump fluid fluidly coupled to a tubular in fluid communication with a wellbore, wherein
the tubular is configured to convey the spacer fluid to the wellbore.

19. The system of claim 18 , further comprising a vessel disposed upstream of the pump, wherein the spacer fluid is disposed in the vessel.
