Title: Computer Simulation of Nuclear Well Logging Devices Final Report CRADA No. TC-824-94F

Abstract

Accurate computer simulation is vital for interpretation of data obtained using nuclear logging tools in exploratory boreholes or existing wells. Millions of dollars are saved when general purpose simulation codes are utilized. Successful interpretation can lead to large increases in recovery efficiency and can aid the industrial competitiveness of the U.S. oil and gas industry. Currently, the computer simulation is done using Monte Carlo codes, which randomly track particles through the tool and the formation. We have developed a deterministic code that does not have statistical uncertainties and should be particularly useful for parameter studies. We use parallel methods to solve the three-dimensional multigroup, neutrodradiation transport equation. We have written and tested the prototype code, running problems on the Cray T3D computer. Also, we have run benchmark problems provided by the industrial partners to test and further develop the code capabilities.
