  • Directional radiation detection tool
    Patent number: 8759749
    Abstract: Various systems and methods for implementing a directional radiation detection tool are disclosed. One such method involves receiving outputs from several radiation sensors (e.g., gamma ray sensors), which are each facing a different direction. The received outputs are then combined, such that a directional error in one of the outputs is reduced, based upon another one of the outputs.
    Type: Grant

  • Gas hold up tool for use in cased well boreholes
    Patent number: 5359195
    Abstract: A method and apparatus for determining the percentage of gas by volume in a well producing mixed phase fluids and flowing up the cased well. A low energy gamma ray source irradiates the flowing fluid and counts are measured by a detector crystal. A metal casing shields the surrounding formations from the gamma radiation so that the detector response is determined primarily by the mixed phase fluids flowing in the well. Calibration enables the determination of gas volume percentage for a specific diameter casing.
