Feasibility of Monte Carlo modelling for the neutron-neutron logging tool response in specific geological models

The neutron well logging is one of the basic methods for determinations of characteristic parameters of the rock samples. The neutron source and neutron detectors are elements of  NNTE logging tool of significant importance. A neutron source creates the neutron field in the nearest environment. Detectors placed at specified distances from the source register neutrons from this space. A signal of NNTE density tool in specific geological conditions was numerically calculated by means of the Monte Carlo (MC) codes. The main aim of this paper is to show the potential of using the MCNP software in nuclear well logging prospection methods. Results of this MC modelling are presented in this paper.
