Abstract

A method of servicing a wellbore in a subterranean formation comprising preparing a wellbore servicing fluid comprising cement, an aqueous fluid, and a cyclodextrin, a cyclodextrin derivative, or combination thereof; placing the wellbore servicing fluid in the wellbore and allowing the fluid to set. A wellbore servicing fluid comprising cement, aqueous fluid, and a cyclodextrin, cyclodextrin derivative, or combination thereof.

First claim

What is claimed is:

1. A wellbore servicing fluid comprising a cementitious material, an aqueous fluid, and at least one of a cyclodextrin, a cyclodextrin derivative, and any combination thereof, wherein the cementitious material comprises at least one cement selected from the group consisting of: a Portland cement, a pozzolana cement, a gypsum cement, a high alumina content cement, a silica cement, a high alkalinity cement, a shale cement, an acid/base cement, a magnesia cement, a fly ash cement, a zeolite cement system, a cement kiln dust cement system, a slag cement, a micro-fine cement, a metakaolin, and any combination thereof.

2. The wellbore servicing fluid of claim 1 wherein the cyclodextrin is selected from the group consisting of: α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin, and any combination thereof.

3. The wellbore servicing fluid of claim 1 wherein the cyclodextrin comprises β-cyclodextrin.

4. The wellbore servicing fluid of claim 1 wherein the cyclodextrin derivative is selected from the group consisting of: acylated cyclodextrin, hydroxyalkylated cyclodextrin, carboxylated cyclodextrin, alkylated cyclodextrin, and any combination thereof.

5. The wellbore servicing fluid of claim 1 wherein the cyclodextrin derivative is selected from the group consisting of: a glucosyl cyclodextrin, a maltosyl cyclodextrin, a methyl cyclodextrin, a hydroxyethyl cyclodextrin, a hydroxypropyl cyclodextrin, a 2-hydroxyethyl cyclodextrin, a carboxymethyl cyclodextrin, a carboxyethyl cyclodextrin, a glucosyl-α-cyclodextrin, a maltosyl-α-cyclodextrin, a glucosyl-β-cyclodextrin, a maltosyl-β-cyclodextrin, a methyl-β-cyclodextrin, a 2-hydroxypropyl-β-cyclodextrin, a hydroxyethyl-β-cyclodextrin, a 2-hydroxypropyl-γ-cyclodextrin, and any combination thereof.

6. The wellbore servicing fluid of claim 1 wherein the cyclodextrin derivative is selected from the group consisting of: a cyclodextrin dimer, a cyclodextrin trimer, a polymerized cyclodextrin, and any combination thereof.

7. The wellbore servicing fluid of claim 1 wherein the cyclodextrin or the cyclodextrin derivative is present in the wellbore servicing fluid in an amount of from about 0.1 wt. % to about 5.0 wt. % by weight of cement.

8. The wellbore servicing fluid of claim 1 wherein the wellbore servicing fluid has a thickening time of from about 3 hours to about 20 hours at a temperature of less than or equal to about 400° F.

9. The wellbore servicing fluid of claim 1 wherein the wellbore servicing fluid displays a right angle set.

10. The wellbore servicing fluid of claim 1 wherein the cyclodextrin, the cyclodextrin derivative, or any combination thereof reduces the viscosity of the wellbore servicing fluid by an amount equal to or greater than about 15%.

11. The wellbore servicing fluid of claim 1 wherein the cementitious material is present in the wellbore servicing fluid in an amount of from about 10 wt. % to about 85 wt. % by weight of wellbore servicing fluid.

12. The wellbore servicing fluid of claim 1 wherein the aqueous fluid is present in the wellbore servicing fluid in an amount from about 20 wt. % to about 180 wt. % by weight of cement.

13. The wellbore servicing fluid of claim 1 wherein the wellbore servicing fluid displays a right angle set.

14. The wellbore servicing fluid of claim 1 wherein the thickening time of the wellbore servicing fluid varies linearly as a function of cyclodextrin concentration.
