  • Subatomic particle detector capable of ignoring shock induced counts
    Patent number: 8907289
    Abstract: A subatomic particle detection apparatus includes a scintillator to scintillate if struck by subatomic particles, and to scintillate if subjected to mechanical stresses, the scintillator to emit an electrical discharge if scintillating due to the mechanical stresses. A detector is optically coupled to the scintillator to detect scintillations by the scintillator. Furthermore, an antenna is associated with the scintillator and/or the detector to detect the electrical discharge. In addition, circuitry is coupled to the detector and the antenna to determine whether the scintillator scintillated due to the mechanical stresses, based upon the antenna detecting the electrical discharge.

  • Method and apparatus for in-situ side-wall core sample analysis
    Patent number: 7500388
    Abstract: A wireline-conveyed side-wall core coring tool for acquiring side-wall core from a geological formation for performing in-situ side-wall core analysis. The coring tool has a core analysis unit operable to measure geophysical properties of an acquired side-wall core. The measured geophysical properties may be used to determine the success of the acquisition of side-wall cores by the coring tool. The core analysis unit is operable of performing an in-situ interpretation of measured geophysical property of the side-wall core and transmitting in near real-time the measurements or the interpretation results to surface data acquisition and processing apparatus.
