  • Detection apparatus comprising a resonant electrical circuit located within a nuclear fuel rod
    Patent number: 12243660
    Abstract: A nuclear fuel rod includes a cladding comprising an interior region. A pressure transmission apparatus is configured to measure pressure in the interior region. Fuel pellets and a resonant electrical circuit are in the interior region. The resonant electrical circuit is configured to generate a pulse that travels wirelessly from the interior region through the cladding. A frequency of the pulse varies based on pressure measured by the pressure transmission apparatus. The frequency of the pulse is indicative of the pressure within the interior region.

  • Apparatus and Method for Underbalanced Drilling and Completion of a Hydrocarbon Reservoir
    Publication number: 20160053542
    Abstract: A system and method for underbalanced drilling and completion of a hydrocarbon reservoir is disclosed. The system prevents formation damage by using a solids-free, non-wetting phase drilling fluid while maintaining underbalanced conditions throughout the entire drilling and completion phase of the operation. By preventing formation damage, this system provides an alternative or supplement to hydraulic fracking.
