Digital Core Permeability Computation by Image Processing Techniques

Calculation of REV (representative elementary volume) properties geological porous media refers to the process creating a 3D digital representation rock sample, typically obtained from imaging techniques such as X-ray microtomography. This technique allows for detailed analysis internal structure and rocks, well precise calculation various flow parameters. However, one major challenge with is high computational cost required generate accurate results, especially large complex samples. In this study, we constructed cores dune sand fractured shale using CT scanning technology, then used two image processing techniques, namely core resampling cutting, reduce calculating permeability. Next, fast permeability method employed complexity calculation. Finally, summarized applicability different methods samples, provided prerequisites
