High-resolution x-ray imaging is used in combination with measurements of permeability and capillary pressure to study multiphase flow in a porous sample. The authors characterized interfaces between brine and oil in a sandstone sample under a variety of conditions. Similar experimental approaches could be useful for other studies.
