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.

Claims (19)

1. A method of servicing a wellbore in a subterranean formation comprising:

preparing 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;

placing the wellbore servicing fluid in the wellbore; and

allowing the wellbore servicing fluid to set.

2. The method 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 method of claim 1 wherein the cyclodextrin derivate is selected from the group consisting of: acylated cyclodextrin, hydroxyalkylated cyclodextrin, carboxylated cyclodextrin, alkylated cyclodextrin, and any combination thereof.

4. The method of claim 1 wherein the cyclodextrin derivatives 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.

5. The method of claim 1 wherein the wherein the cyclodextrin derivatives is selected from the group consisting of: a cyclodextrin dimer, a cyclodextrin trimer, a polymerized cyclodextrin, and any combination thereof.

6. The method of claim 1 wherein the cyclodextrin comprises β-cyclodextrin.

7. The method of claim 1 wherein the cyclodextrin, cyclodextrin derivative, or combination thereof 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 method of claim 1 where in the cementitious material comprises at least one cement selected from the group consisting of: a Portland cement, a pozzolana cement, a gypsum cement, a phosphate 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.

9. The method 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.

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

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

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

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

14. The method of claim 1 wherein the wellbore servicing fluid displays an operational window of at least from about 80° F. to about 400° F.

15. The method of claim 1 wherein the wellbore servicing fluid displays a change in thickening time at 250° F. of equal to or less than about a factor of 10 in response to a change in concentration of at least one of the cyclodextrin, the cyclodextrin derivative, and any combination thereof.
