Conversion of Old Gamma Logs

[Count per second (cps) to Density & Porosity (g/cc, kg/m3, phi-φ)]

Old style Neutron Log/ Gamma-Gamma Log or Sidewall Neutron (SNP) which recorded the Gamma ray count rates in count per second (cps). These are obsolete now and there is a need to convert them into modern Density & Porosity units (g/cc, φ) to make them useful for the petrophysicist.

We make this conversion possible by using Semi-Logarithmic approach and High porosity- Low porosity method, equations, graphs and charts.
