is designed to determine rock effective atomic number within ore/coal wellbores.

 

 

Description

Features and advantages:

  • tool small diameter;
  • controlled skid original design;
  • small linear dimensions of the probe GGK-S (240 mm);
  • sonde offset high amplitude (up to 200mm);
  • metrological provision and calibration devices;
  • problems to solve;
  • rock lithologic breaking up;
  • delineation of coal bed and identification of their zonality.

GGK-S-43 tools are to be run with triple-core logging cable.
