Abstract

A composition including a particulate, water, and a suspension aid comprising graphene, wherein the graphene comprises bioderived renewable graphene (BRG) and wherein the particulate is suspended in the composition. Methods of making and using the composition are also provided.

First claim

What is claimed is:

1. A method of making a composition comprising suspended particulates, the method comprising:
combining a suspension aid and water to form a mix water, wherein the suspension aid comprises graphene, wherein the graphene comprises bioderived renewable graphene (BRG);
combining the mix water with the particulate to provide the composition having the particulates suspended therein; and
placing the composition in a workspace,
wherein the suspended particulates remain suspended in the composition during free fluid testing, as measured according to API 10B-2, for at least 60 minutes, and
wherein the composition comprises greater than or equal to 5 percent BRG by weight of water (% BRG bwow).

2. The method of claim 1 , wherein the BRG comprises graphene derived from a plant.

3. The method of claim 1 , wherein the BRG comprises graphene with a fused sheet-like morphology.

4. The method of claim 1 , wherein the particulate comprises sand, a weighting agent, rubber particles, a mechanical property modifier, iron oxide, polymer particles, glass spheres, a pozzolanic material, a lost circulation material, another water insoluble particle, or a combination thereof.

5. The method of claim 1 , wherein the suspension aid consists essentially of the BRG.

6. The method of claim 1 , wherein the composition comprises greater than or equal to 10 percent BRG by weight of water (% BRG bwow).

7. The method of claim 1 , wherein the plant comprises cassava.

8. The method of claim 1 , wherein the particulate has a density of greater than water.

9. The method of claim 1 , wherein the particulate has an average diameter of less than or equal to about 5000 micrometers.

10. The method of claim 1 , wherein the suspended particulates remain suspended in the composition during free fluid testing, as measured according to API 10B-2, for at least 120 minutes.

11. A method of suspending particulates, the method comprising:
combining the particulates with a carrier fluid comprising water and a suspension aid comprising graphene to provide an aqueous suspension of the particulates in the carrier fluid, wherein the graphene comprises bioderived renewable graphene (BRG), and wherein the suspended particulates remain suspended in the aqueous suspension during free fluid testing, as measured according to API 10B-2, for at least 60 minutes, and wherein the aqueous suspension comprises greater than or equal to 5 percent BRG by weight of water (% BRG bwow).

12. The method of claim 11 , wherein the graphene comprises graphene with a fused sheet-like morphology.

13. The method of claim 11 , wherein the BRG comprises graphene derived from a plant.

14. The method of claim 11 , wherein the particulate comprises sand, a weighting agent, rubber particles, a mechanical property modifier, iron oxide, polymer particles, glass spheres, a pozzolanic material, a lost circulation material, another non-water soluble particle, or a combination thereof.

15. The method of claim 11 , wherein the suspension aid consists of or consists essentially of the BRG.

16. The method of claim 11 , wherein the aqueous suspension comprises greater than or equal to 15 percent BRG by weight of water (% BRG bwow).

17. The method of claim 11 , wherein the plant comprises cassava.

18. The method of claim 11 , wherein the particulate has a density of less than water.

19. The method of claim 11 , wherein the aqueous suspension comprises greater than or equal to 10 percent BRG by weight of water (% BRG bwow).

20. The method of claim 11 , wherein the particulate has an average diameter of less than or equal to about 500 micrometers.
