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 method of treating an oil and gas well, comprising:
introducing a well treatment fluid into the well, said well treatment fluid including:
an aqueous base fluid; and
a sugar-based surfactant, said sugar-based surfactant including a betaine functionalized alkyl polyglucoside having the following formula:

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

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

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

4. The method 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 method 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 method 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.

7. The method of claim 1 , further comprising mixing the well treatment fluid using mixing equipment.

8. The method of claim 1 , wherein the well treatment fluid is introduced into a subterranean formation using one or more pumps.

9. The method 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, and 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.

10. The method of claim 9 , wherein said betaine functionalized alkyl polyglucoside(s) is manufactured using a renewable carbon source.

11. The method of claim 10 , wherein said renewable carbon source is selected from the group consisting of corn, coconut and mixtures thereof.

12. A method of treating an oil and gas well, comprising:
introducing a well treatment fluid into the well, said well treatment fluid being an aqueous based fracturing fluid and including:
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.

13. The method of claim 12 , wherein said betaine functionalized alkyl polyglucoside is manufactured using a renewable carbon source.

14. The method of claim 13 , wherein said renewable carbon source is selected from the group consisting of corn, coconut and mixtures thereof.

15. The method of claim 12 , 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.

16. The method of claim 12 , wherein the well treatment fluid is introduced into a subterranean formation using one or more pumps.

17. The method of claim 12 , further comprising mixing the well treatment fluid using mixing equipment.

18. The method of claim 12 , 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.

19. The method of claim 18 , wherein said betaine functionalized alkyl polyglucoside is manufactured using a renewable carbon source.

20. The method of claim 19 , wherein said renewable carbon source is selected from the group consisting of corn, coconut and mixtures thereof.
