Abstract (en)
[origin: WO2013184457A1] A fluid may contain nanoparticles and a base fluid where the base fluid may be a non-aqueous fluid. The base fluid may be, but is not limited to a drilling fluid, a completion fluid, a production fluid, and/or a stimulation fluid. The fluid may have at least one property, such as but not limited to a relative dielectric constant ranging from about 5 to about 10,000, an electrical conductivity ranging from about 1x10-6 S/m to about 1 S/m, and combinations thereof. The non aqueous fluid may be a brine-in-oil emulsion, or a water-in-oil emulsion, and combinations thereof. The addition of nanoparticles to the base fluid may modify the electrical properties of the fluid.
