The lithodensity logging (LDL) tool is used in oil-well logging to determine formation density and effective atomic number (related to the formation lithology). It generally contains a gamma-ray source collimated to emit photons toward the formation and two collimated gamma-ray detectors that measure the counting rates from back scattered photons. Simulation of the response of this tool by Monte Carlo methods presents a very difficult problem because the counting yield (counts per source photon) is only of the order of 10[sup [minus]7] for the far detector. Thus, optimal use of variance reduction methods is vital for efficient Monte Carlo simulation of the LDL tool.
