  • Patent number: 11879091
    Abstract: Methods are disclosed for emplacing a gel-form material in a porous subterranean formation, such as a hydrocarbon reservoir. The material is formed by admixing solid nanoparticles with gelation supporting amounts of surfactants or ionic species, such as ionic species of the kind that form ionic liquids. The nanoparticle to ion ratio may be selected, in combination with selecting the components of the gel-form material, so that the rheological and gelation properties of the gel-form material are adapted for a particular use, for example forming a fluid flow barrier in a reservoir.

  • Publication number: 20230365417
    Abstract: Methods are disclosed for dispersing nanoparticles in solvents, involving the use of a cationic species and an anionic species, where at least one of the ionic species is soluble in the nonpolar solvent and the other ionic species has a relatively strong affinity for the surface of the nanoparticles. The cationic species and the anionic species together form a cluster of ion pairs shielding the nanoparticles and enhancing their dispersibility in the nonpolar solvent.

  • Publication number: 20230052546
    Abstract: The present disclosure describes a method of recycling an expired hand sanitizer product containing ethanol in an amount ranging from 60 to 85 wt %, wherein said method comprises the steps of: providing said hand sanitizer product; combining said hand sanitizer product with an anionic surfactant; adding a nonionic surfactant to the resulting mixture; and adding citral to the mixture containing said hand sanitizer, nonionic surfactant and said anionic surfactant to create a stable microemulsion; wherein said stable microemulsion can be further diluted with an acidic composition to be used in industrial applications comprising: flowback aids for hydraulic fracturing in tight reservoirs and unconventional shale reservoirs; naphthenate deposition control using acids/alcohols mixtures; or water-in-oil demulsifier using ethanol for bitumen emulsions from oilsand.
