AUTOMATED SAW CUT CORRECTION FOR 3D CORE DIGITAL MODELING FROM COMPUTERIZED TOMOGRAPHY SCANNER (CTS) IMAGES

摘要

Computer-implemented methods, systems, and non-transitory computer-readable medium having computer program stored therein are provided to enhance the accuracy and efficiency of modeling a core sample from images of two-dimensional transverse sections of a core sample. Embodiments of the invention include, for example, image registering a plurality of images of transverse sections of a core sample to produce aligned transverse sections by approximating the circular location of the boundary of the transverse section and aligning the images based on center points of the approximated circles. Embodiments can further include, for example, performing a saw cut correction on the aligned transverse section images to adjust the images for the slab cut, generating a three-dimensional simulated model of the core sampling using or more of the saw cut line corrected images, and generating a three-dimensional simulated model of the internal composition of a borehole related to the core sample using multipoint statistics calculations.
