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).
