Monte Carlo Simulation Of Pulse Height Spectra In Nuclear Logging Density Tools

Abstract

The response functions of nuclear tools for well logging are generally characterized by means of measurements made in calibrated test formations. Numerical simulations of the tool performance can be used to extend these characterizations to conditions which are inconvenient or costly to reproduce in the laboratory. The simulations reported here were performed to determine the response of a commercial spectral density tool in a heavy mud cake environment.
