Re: Converting Russian neutron log unit to conventional unit
I believe you must be the same person who posted the same question on 18 November 2013.
Generally, neutron count rates are indirectly proportional to porosity. The lower the count rate, the higher the porosity and vice versa.
However, to convert the count rates into porosity, you need a reference or some form of calibration.
It will be helpful if you have some other logs like sonic to calibrate your neutron porosity.
Some further information on Russian type neutron logs can be found at the following website:https://www.spec2000.net/17-russian.htm
It is the link to Crain's Petrophysical Handbook, which is an extremely useful reference book on petrophysics.
