Abstract

A method of drilling is disclosed that includes introducing a water-based drilling fluid into a drill string disposed within a wellbore, circulating the water-based drilling fluid through the drill string and the wellbore, and extending the wellbore using the drill string while circulating the water-based drilling fluid, wherein the water-based drilling fluid includes water and a lubricating additive including a de-oiled cake, wherein the de-oiled cake are residues obtained after extraction of oil from a plant source, wherein the de-oiled cake is in particulate form having a particle size of 100 microns or less. A composition is disclosed that includes water-based drilling fluid including water and a lubricant additive comprising a de-oiled cake, wherein the de-oiled cake are residues obtained after extraction of oil from a plant source and wherein the de-oiled cake has a particle size of 100 microns or less.

First claim

What is claimed is:

1. A method of drilling comprising:
introducing a water-based drilling fluid into a drill string disposed within a wellbore;
circulating the water-based drilling fluid through the drill string and the wellbore; and
extending the wellbore using the drill string while circulating the water-based drilling fluid,
wherein the water-based drilling fluid comprises:
water; and
a lubricating additive comprising a de-oiled cake, wherein the de-oiled cake are residues obtained after extraction of oil from a plant source, wherein the de-oiled cake is in particulate form having a particle size of 100 microns or less.

2. The method of drilling of claim 1 , wherein the plant source comprises at least organic material selected from the group consisting of peanut, coconut, soybean, sunflower, cottonseed, safflower, palm, rapeseed, corn, olive, sesame, almond, walnut, mustard, rice bran, and any combination thereof.

3. The method of drilling of claim 1 , wherein the de-oiled cake has a particle size of 90 microns or less.

4. The method of drilling of claim 1 , wherein the de-oiled cake has a particle size of 65 microns or less.

5. The method of drilling of claim 1 , wherein the largest particle size of the de-oiled cake is in a range of 30 μm to 100 μm.

6. The method of drilling of claim 1 , wherein the de-oiled cake is present in an amount of about 1% to about 50% by weight of the water-based drilling fluid.

7. The method of drilling of claim 1 , wherein the water-based drilling fluid forms a fluid column disposed within the wellbore and wherein the de-oiled cake is present throughout the fluid column.

8. The method of drilling of claim 1 , further comprising preparing the water-based drilling fluid by mixing a dry blend comprising the de-oiled cake with the water to form the water-based drilling fluid.

9. The method of drilling of claim 1 , further comprising preparing the water-based drilling fluid by mixing a liquid additive comprising the de-oiled cake with the water to form the water-based drilling fluid.

10. The method of claim 9 , wherein the liquid additive comprises an oleaginous carrier fluid.

11. The method of drilling of claim 1 , wherein the water-based drilling fluid has a coefficient of friction of 0.25 or less.

12. The method of drilling of claim 1 , wherein a weighting agent is present in the water-based drilling fluid in an amount of about 1% to about 60% by weight of the water-based drilling fluid.

13. The method of drilling of claim 1 , wherein the water-based drilling fluid has a pH of about 7 to about 12.

14. The method of drilling of claim 1 , wherein the water-based drilling fluid has a density of about 0.5 g/cc to about 4 g/cc.

15. A method of drilling comprising:
introducing a water-based drilling fluid into a drill string disposed within a wellbore;
circulating the water-based drilling fluid through the drill string and the wellbore; and
extending the wellbore through a non-loss zone using the drill string while circulating the water-based drilling fluid,
wherein the water-based drilling fluid comprises:
water; and
a lubricating additive comprising a de-oiled cake, wherein the de-oiled cake are residues obtained after extraction of oil from a plant source.

16. A water-based drilling fluid comprising:
water; and
a lubricant additive comprising a de-oiled cake, wherein the de-oiled cake are residues obtained after extraction of oil from a plant source and wherein the de-oiled cake has a particle size of 100 microns or less.

17. The water-based drilling fluid of claim 16 , wherein the de-oiled cake has a particle size of 75 microns or less.

18. The water-based drilling fluid of claim 16 , wherein the de-oiled cake is present in an amount of about 1% to about 50% by weight of the water-based drilling fluid.

19. The water-based drilling fluid of claim 16 , wherein a weighting agent is present in the drilling fluid in an amount of about 1% to about 60% by weight of the drilling fluid.

20. The water-based drilling fluid of claim 16 , wherein the water-based drilling fluid has a density of about 0.5 g/cc to about 4 g/cc.
