Abstract

A well treatment fluid comprising an aqueous base fluid and a sugar-based surfactant is provided. The sugar-based surfactant includes at least one betaine functionalized alkyl polyglucoside. Also provided is a method of treating an oil and gas well.

First claim

What is claimed is:

1. A well treatment fluid, comprising:
an aqueous base fluid; and
a sugar-based surfactant, said sugar-based surfactant including at least one betaine functionalized alkyl polyglucoside having the following formula:

wherein R contains 12 or 14 carbon atoms, and n is a finite number.

2. The well treatment fluid of claim 1 , wherein said betaine functionalized alkyl polyglucoside(s) is manufactured using a renewable carbon source.

3. The well treatment fluid of claim 2 , wherein said renewable carbon source is selected from the group consisting of corn, coconut and mixtures thereof.

4. The well treatment fluid of claim 1 , wherein said sugar-based surfactant is present in said well treatment fluid in an amount in the range of from about 0.00001% to about 30% by volume, based on the total volume of said treatment fluid.

5. The well treatment fluid of claim 4 , wherein said sugar-based surfactant is present in said well treatment fluid in an amount in the range of from about 0.001% to about 10% by volume, based on the total volume of said treatment fluid.

6. The well treatment fluid of claim 5 , wherein said sugar-based surfactant is present in said well treatment fluid in an amount in the range of from about 0.01% to about 3% by volume, based on the total volume of said treatment fluid.

7. The well treatment fluid of claim 1 , wherein the well treatment fluid is an injection fluid, a drilling fluid, a pre-flush fluid, a cement composition, a completion fluid, a work-over fluid, or a stimulation fluid.

8. The well treatment fluid of claim 7 , wherein said betaine functionalized alkyl polyglucoside(s) is manufactured using a renewable carbon source.

9. The well treatment fluid of claim 8 , wherein said renewable carbon source is selected from the group consisting of corn, coconut and mixtures thereof.

10. The well treatment fluid of claim 9 , wherein said sugar-based surfactant is present in said well treatment fluid in an amount in the range of from about 0.01% to about 3% by volume, based on the total volume of said treatment fluid.

11. A fracturing fluid, comprising:
an aqueous base fluid;
one or more proppant particulates; and
a sugar-based surfactant, said sugar-based surfactant including at least one betaine functionalized alkyl polyglucoside having the following formula:

wherein R contains 12 or 14 carbon atoms, and n is a finite number.

12. The well treatment fluid of claim 11 , wherein said betaine functionalized alkyl polyglucoside(s) is manufactured using a renewable carbon source.

13. The well treatment fluid of claim 12 , wherein said renewable carbon source is selected from the group consisting of corn, coconut and mixtures thereof.

14. The fracturing fluid of claim 11 , wherein said sugar-based surfactant is present in said fracturing fluid in an amount in the range of from about 0.00001% to about 30% by volume, based on the total volume of said fracturing fluid.

15. The well treatment fluid of claim 14 , wherein said sugar-based surfactant is present in said well treatment fluid in an amount in the range of from about 0.001% to about 10% by volume, based on the total volume of said treatment fluid.

16. The well treatment fluid of claim 15 , wherein said sugar-based surfactant is present in said well treatment fluid in an amount in the range of from about 0.01% to about 3% by volume, based on the total volume of said treatment fluid.

17. The well treatment fluid of claim 11 , wherein said aqueous base fluid includes one or more of clay control agents, gels, gelling agents, gel stabilizers, cross-linkers, breakers and viscosifying agents.

18. The well treatment fluid of claim 17 , wherein said betaine functionalized alkyl polyglucoside(s) is manufactured using a renewable carbon source.

19. The well treatment fluid of claim 18 , wherein said renewable carbon source is selected from the group consisting of corn, coconut and mixtures thereof.

20. The well treatment fluid of claim 19 , wherein said sugar-based surfactant is present in said well treatment fluid in an amount in the range of from about 0.01% to about 3% by volume, based on the total volume of said treatment fluid.
