MGST Multichannel GR Spectrum Tool

When a gamma ray enters into the NaI crystal, the photo multiplier outputs a pulse with amplitude proportional to gamma ray energy absorbed by NaI crystal. It adopts spectrum stabilization technology to set up windows with different energies.

NLDS-MFS Net-Oriented Litho Density Sonde and Micro Sphererical Focused Sonde

The Litho-Density tool uses a gamma source (1.5Ci, Cs137) and two detectors of different spacing to contact the sidewall directly. Based on Photoelectric Effect and Compton Effect, corresponding energy windows are set up, recording the gamma ray of various windows, and measuring the lithology and density of formation.
