TzGS-1 digital gamma-ray spectrometer

is designed foe Uranium, Thorium, Potassium content determination along oil and gas wells up to 10000 m deep and 55-300 mm in diameter through nature gamma-ray energy distribution.

Description

TzGS tool can be combined with any type of computerized well logging stations.

Features and Advantages

  • interval-by-interval gamma-ray spectra accumulation in the downhole tool for the further digital data telemetering;
  • natural gamma-spectrum soft component analysis;
  • improved accuracy while U, Th, K content determination.
