Rock sample analysis using sem imaging for pore size determination
A recently granted patent (Publication Number: US11885757B2) discloses a method and system for analyzing rock samples using scanning electron microscope (SEM) imaging. The method involves generating two-dimensional (2D) SEM images of physical faces of a rock sample, applying a cross-correlation function to these images to create a three-dimensional (3D) digital model volume, and determining the probability distribution of pore size based on image intensity values. The resolution of the 3D digital model volume is finer than that of the digital image volume, and different axial orientations of SEM images can be analyzed. Additionally, the system can compare rock samples from different geographic regions, generate multiple 3D digital model volumes for various rock fabrics, and perform direct numerical simulations to determine pore size probability distributions.
Furthermore, the patent includes a non-transitory, computer-readable medium with encoded instructions for executing the analysis process. These instructions enable the processor to receive 2D SEM images, apply cross-correlation functions to generate 3D digital model volumes, and determine pore size probability distributions based on image intensity values. Similar to the method, the medium allows for analyzing rock samples from different geographic regions, generating multiple 3D digital model volumes for various rock fabrics, and updating pore size probability distributions based on aggregated results. The patent showcases an innovative approach to rock sample analysis using SEM imaging and digital modeling, offering a comprehensive method for understanding pore size distributions in different types of rock fabrics.
