... of the epithermal neutron counts. Its stated advantages are that it is not impacted by absorbers, is a direct measure of the hydrogen index, and has a greater depth-of-investigation. However, its field performance has not been consistent. [Badruzzaman 2005] Appendix A discusses an example from the cited reference...

... ABSTRACT: Epithermal and thermal-neutron porosity measurements each have distinct advantages and disadvantages. Foremost, epithermal neutron porosity is less sensitive to the neutron absorbers found in saline water and certain clays. However, epithermal neutron measurements typically suffer...

... ABSTRACT Monte Carlo modelling of the MWD neutron porosity configuration reveals that the thick steel wall of the drill collar has a significant influence on the relative population of epithermal neutrons, thermal neutrons, and capture gamma radiation. The drill collar provides a channel...
