  • Patent number: 10668440
    Abstract: Dust produced by handling proppant during fracking or other mechanical operations can be a health and/or safety hazard. The dust can be eliminated or at least mitigated using a method of conducting a hydraulic fracturing or other mechanical operation on an oil or gas well including treating a proppant that has been transported to an end use site at a level sufficient to prevent the formation of dust during handling of the proppant.
