METHOD FOR ESTIMATING EFFECTIVE ATOMIC NUMBER AND BULK DENSITY OF ROCK SAMPLES USING DUAL ENERGY X-RAY COMPUTED TOMOGRAPHIC IMAGING

摘要

A method for estimating effective atomic number and bulk density of objects, such as rock samples or well cores, using X-ray computed tomographic imaging techniques is provided. The method effectively compensates for errors in the interpretation of CT scan data and produces bulk densities which have lower residual error compared to actual bulk densities and produces bulk density—effective atomic number trends which are consistent with physical observations.
