ABSTRACT:
In order to correlate information of a core sample taken from a borehole with information derived from an original position of the core sample in the borehole, the core is scanned using computed tomography (CT) to generate core slices having first depths assignable thereto based upon a drilling record. The core slices are concerted to first bulk density data using either region-of-interest statistics or selective histogram statistics, which is then compared to second bulk density data obtained from logging at respective second depths to obtain a good match between the first and second depths.
