Pore-scale images of trapped immiscible fluid structures in oil-wet and water-wet bead packs

The objective of this study was to obtain quantitative evidence of pore-scale immiscible fluid distribution in oil-wet and water-wet porous media using X-ray computed microtomography. Raw CMT image data sets for multiple flooding experiments using kerosene and brine are included for an oil-wet polyethylene bead pack, and a single imbibition/drainage cycle for a water-wet glass bead pack.
