  • CONTROLLABLY TUNING PROPERTIES OF A FLUID USING MODIFIED NANOPARTICLES
    Publication number: 20130341028
    Abstract: Properties of a base fluid may be controllably tuned to a pre-determined range of measurements by adding modified nanoparticles to a base fluid. The property to be modified may be or include, but is not limited to, electrical conductivity, dielectric strength, thermal conductivity, and combinations thereof. The modified nanoparticles may be or include modified graphene nanoparticles, modified graphene platelets, modified electrically-conductive nanotubes, modified electrically-conductive nanorods, nanospheres, single-walled nanotubes, double walled nanotubes, multiwalled nanotubes, nano-onions, fullerenes, nanodiamonds, and combinations thereof. The base fluid may be or include, but is not limited to a non-aqueous based fluid, an aqueous fluid, and combinations thereof.

  • Electrically Conductive Oil-Base Fluids for Oil and Gas Applications
    Publication number: 20120322694
    Abstract: A base fluid may contain nanoparticles where the base fluid may include a non-aqueous fluid, an aqueous fluid, and combinations thereof. The fluid may have a resistivity range of from about 0.02 ohm-m to about 1,000,000 ohm-m. The non-aqueous fluid may be a brine-in-oil emulsion, or a water-in-oil emulsion; and the aqueous fluid may be an oil-in-water emulsion, or an oil-in-brine emulsion; and combinations thereof. The addition of nanoparticles to the base fluid may improve or increase the electrical conductivity and other electrical properties of the fluid. The fluid may be a drilling fluid, a completion fluid, a production fluid, and/or a stimulation fluid.
