•We investigate if 3D models from FIB-SEM image stacks are a suitable REV for shale.•Data include groups of local 2D and 3D images and corresponding core measurements.•Image analysis of image stacks and LBM fluid flow simulations are performed.•We conclude that FIB-SEMs are not suitable domains for permeability simulations.•Averaging local 2D and 3D images can provide representative volumetric properties.
