  • Patent number: 11236258
    Abstract: Compositions and methods of reducing release of fugitive dust from particulate substrates are provided. The method involves applying a composition onto the substrate in an amount effective to reduce dust release and remain effective for an extended period of time, wherein the composition comprises an aqueous medium, a surface modifying agent, and a dispersant.
    Type: Grant
    Filed: January 14, 2019
    Date of Patent: February 1, 2022

  • Patent number: 11130892
    Abstract: Methods and compositions for suppressing fugitive dust are provided herein. To suppress fugitive dust, particulate materials, dust and or substrates can be treated with a mixture having a hydrophobizing agent and an oil. The hydrophobizing agent can be an organo- or halosilane, a tallow alkylamine, an amine-functionalized polysiloxane, or an amine-functionalized hydrophobic polymer.

  • Publication number: 20200157415
    Abstract: The present disclosure is directed to the use of dendrimers in various compositions and methods applicable in oilfield applications, such as, but not limited to, in compositions containing oilfield chemical additives for enhancing the efficacy of the oilfield chemical additives in such compositions and in compositions containing an aqueous liquid to allow the compositions to exhibit an enhanced water imbibition in a subterranean hydrocarbon-bearing formation.

  • Publication number: 20170306219
    Abstract: Particulates, such as proppants, that are coated with a coating agent selected from the group consisting of: organosilanes, organosiloxanes, polysiloxanes, long carbon chain hydrocarbon amines containing no silicon or fluoro-based groups in the molecule, amine functionalized polyolefins and polymerizable natural oils; and a chemical additive selected from the group consisting of: a scale inhibitor, a biocide, and an H2S scavenger. The coating agent controls the release of the additive from the particulate surface into surrounding fluid, providing a slow release that promotes the long lasting effect of the additive. The coated particulates have use in oilfield applications such as hydraulic fracturing operations, gravel pack operations, and in water treatment processes.
