Compensated Density Logging Tool

Brief Introduction:

CDL uses Cs137 gamma source to emit gamma rays with energy of 0.662MeV, and Compton scattering is used to measure formation volume density.

This tool, compensated neutron logging tool and acoustic logging tool can determine formation porosity.
