Computer Simulation of Nuclear Well Logging Tools

abstract

Nuclear well logging is a widely used technique in the oil and gas industry
for analyzing the materials surrounding exploratory boreholes. A tool
consisting of a neutron or gamma-ray source and one or more detectors is
lowered into the borehole and measurements are recorded in a "log". The
response of the detectors to radiation returning from outside the borehole
depends upon the lithology, porosity, and fluid characteristics of the
material. In principle, the characteristics of the materials outside the
borehole can be inferred from the response of the detectors.
