      Rugged Extreme Environment

      Extreme Environment (Ruggedized)

      The primary use of our ruggedized detectors is for oil and gas exploration. Our reputation for designing and manufacturing detectors capable of surviving use in the harsh environmental conditions of oil exploration has gained us wide recognition and acceptance in this industry.

      Our detectors, as integral components of gamma ray logging tools, provide superior performance and survivability under the most extreme environmental conditions. The newer generation of exploration and production logging tools place incredible performance demands on scintillation-based sub-assemblies.  Several patented features in Saint-Gobain crystal packages and our series of integrated detector designs provide gamma logging professionals significant advantages.

       

      • NaI(Tl) : Versatile, industry standard for wireline and MWD applications
      • CsI(Na): Intermediate light output and gamma stopping power without intrinsic radioactivity for wireline applications
      • CsI(Tl): One of the brightest scintillator with very good stopping power
      • BGO : High gamma stopping power for wireline logging, without intrinsic radioactivity
      • LaBr3(Ce) : Highest light output at temperature, fast counting for pulse neutron activated measurement
