Research and production enterprise that creates special and unique methods and technologies for geophysical research of oil and gas, ore and coal wells

  • +7 (34767) 7-19-00


Designed to measure full spectra of characteristic X-ray radiation of atoms of elements that make up the rocks and ores during the logging of ore, coal, hydrogeological and special wells. The tool provides quantitative determination of chemical element contents in formations intersected by wells.

The downhole tool is to be run with VULCAN V3 log recorder or similar.

Operates with one-core (optional) or three-core logging cable.
