Abstract: Sensing systems include a tube defining a Fabry-Perot cavity and an optical fiber including a distal end disposed within the Fabry-Perot cavity and a proximal end. A corrodible material caps the Fabry-Perot cavity. Devices for sensing corrosion of downhole equipment include an optical fiber with a corrodible material disposed over a distal end of the optical fiber. Systems for sensing a condition in equipment include an optical fiber with a fiber Bragg grating proximate a distal end thereof and a mass of sensor material coupled to the distal end of the optical fiber. The mass of sensor material is suspended from above the fiber Bragg grating. Other systems for sensing a condition in a wellbore include an optical fiber and a plurality of fiber Bragg gratings along a length thereof. A plurality of sensor materials are coupled to the optical fiber and surround respective fiber Bragg gratings.

Abstract: Devices and methods for detecting chemicals are disclosed. A device configured for use in a wellbore includes a sensor including a quantum tunneling composite (QTC) material configured to exhibit a change in electrical resistance responsive to the sensor contacting a target chemical. The sensor includes electrical resistance measuring circuitry operably coupled to the QTC material and configured to measure the electrical resistance of the QTC material and output a sensor signal indicating the electrical resistance. A method comprises deploying the sensor into the wellbore, measuring the electrical resistance of the QTC material, and determining the presence of the target chemical responsive to detecting changes in the electrical resistance of the QTC material. Another method includes selecting at least one of the QTC material and an active material to interact with a target wellbore chemical to change the electrical resistance of the QTC material.

Abstract: 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.
