Database and code to the paper: A multiscale CNN-based intrinsic permeability prediction in deformable porous media. Including: (1) a dataset of CT images from Bentheim sandstone at different volumetric strain levels; (2) pore-scale permeability simulation data of single-phase flow using the lattice Boltzmann method (LBM); (3) the CNN model with the processed CT images as inputs and permeability tensors as outputs; and (4) data augmentation and alternative CNN architectures.
