From Segmentation of Shale Rocks FIB/SEM Images to Properties Simulation and High Resolution Mineralogy

New segmentation techniques applicable for 3D FIB/SEM shale rock samples can be used to accurately extract the pore structure and minerals. Combined with BSE and EDS electron microscopy images fusion, the mineralogy can now be obtained in real time at a high resolution. From these initial steps, material properties such as absolute permeability and molecular diffusivity can be obtained in a reasonable time, taking advantage of modern graphic hardwares. This will be presented as a complete workflow for core analysis.
