Abstract

A method and a composition for suppressing and eliminating dust particulate. The composition includes an aqueous gelling solution, and a proppant particulate. The aqueous gelling solution and the proppant particulate are combined to create a mixture. The aqueous gelling solution and the proppant particulate may be combined using at least one of composition spraying the aqueous gelling solution, mist spraying the aqueous gelling solution, and atomized spraying aqueous gelling solution. The mixture may include around 0.1 weight percent to 5 weight percent w/v of the aqueous gelling solution. The gelling agent may include a suitable viscosifying polymer. The suitable viscosifying polymer may include at least one of natural polymers, derivatives of natural polymers, synthetic polymers, biopolymers, and any combination thereof, guar, xanthan, diutan, scleroglucan, high-molecular weight polysaccharides, any derivative thereof, and any combination thereof, hydropropyl guar (HPG), carboxymethyl guar (CMG), and carboxymethylhydroxypropyl guar (CMHPG).

First claim

We claim:

1. A method for suppressing and/or eliminating dust particulate comprising:
providing an aqueous gelling agent solution;
providing a proppant particulate that includes dust particulate;
applying the aqueous gelling agent solution to the proppant particulate by spraying, applying as a mist, or atomizing into a dry flow stream for a time of one minute or greater to encapsulate the dust particulate onto a surface of the proppant particulate thereby creating a mixture; and
conveying the mixture to or from a storage container.

2. The method of claim 1 , further comprising:
wherein the applying the aqueous gelling agent solution to the proppant particulate is performed prior to conveying the mixture to or from the storage container.

3. The method of claim 2 , further comprising pumping the mixture into a subterranean formation.

4. The method of claim 3 , further comprising:
utilizing a pump for pumping the mixture.

5. The method of claim 2 , further comprising:
placing the proppant particulate into a fracture in a subterranean formation.

6. The method of claim 1 , wherein the applying step comprises: spraying the aqueous gelling agent solution onto the proppant particulate.

7. The method of claim 1 , wherein the applying step comprises:
applying the aqueous gelling agent solution onto the proppant particulate as a mist.

8. The method of claim 1 , wherein the mixture comprises around 0.1 percent volume by weight to 5 percent volume by weight of the aqueous gelling solution to the proppant particulate.

9. The method of claim 1 , wherein the gelling agent comprises a viscosifying polymer.

10. The method of claim 9 , wherein the viscosifying polymer comprises at least one of natural polymers, derivatives of natural polymers, synthetic polymers, biopolymers, and any combination thereof.

11. The method of claim 9 , wherein the viscosifying polymer comprises at least one of hydropropyl guar (HPG), carboxymethyl guar (CMG), and carboxymethylhydroxypropyl guar (CMHPG).

12. The method of claim 9 , wherein the viscosifying polymer comprises at least one of hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), carboxymethylcellulose (CMC), or carboxymethylhydroxyethylcellulose (CMHEC).

13. The method of claim 9 , wherein the viscosifying polymer comprises at least one of polyacrylamide and polyacrylate polymers, polyvinyl alcohol, polyethylene glycol, polypropylene glycol, and copolymers thereof.

14. The method of claim 1 , wherein the proppant particulate comprises at least one of natural sand, resin-coated sand, crushed nut hulls, polymer beads, and man-made ceramic materials.

15. A method for suppressing and/or eliminating dust particulate comprising: providing an aqueous gelling agent solution;
providing a proppant particulate that includes dust particulate;
applying the aqueous gelling agent solution to the proppant particulate by spraying, applying as a mist, or atomizing into a dry flow stream for a time of one minute or greater to encapsulate the dust particulate onto a surface of the proppant particulate thereby creating a mixture;
conveying the mixture to or from a storage container; and
utilizing a pump for pumping the mixture.

16. The method of claim 15 , further comprising: utilizing a mixer for mixing the mixture.

17. The method of claim 15 , further comprising pumping the mixture into a subterranean formation.

18. The method of claim 15 , further comprising: placing the proppant particulate into a fracture in a subterranean formation.

19. The method of claim 15 , wherein the applying step comprises: spraying the aqueous gelling agent solution onto the proppant particulate.

20. The method of claim 15 , wherein the mixture comprises around 0.1 percent volume by weight to 5 percent volume by weight of the aqueous gelling solution to the proppant particulate.

21. The method of claim 15 , wherein the aqueous gelling agent comprises a viscosifying polymer.

22. The method of claim 21 , wherein the viscosifying polymer comprises at least one of hydropropyl guar (HPG), carboxymethyl guar (CMG), and carboxymethylhydroxypropyl guar (CMHPG).

23. The method of claim 21 , wherein the viscosifying polymer comprises at least one of hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), carboxymethylcellulose (CMC), or carboxymethylhydroxyethylcellulose (CMHEC).

24. The method of claim 21 , wherein the viscosifying polymer comprises at least one of polyacrylamide and polyacrylate polymers, polyvinyl alcohol, polyethylene glycol, polypropylene glycol, and copolymers thereof.

25. The method of claim 21 , wherein the viscosifying polymer comprises at least one of guar, derivatized guar, derivatized cellulose, and synthetic polymers.
