This work utilizes synchrotron-based x-ray computed microtomography (x-ray CMT) imaging to quantify
the volume and topology of supercritical carbon dioxide (scCO₂) on a pore-scale basis throughout the
primary drainage process of a 6 mm diameter Bentheimer sandstone core. Experiments were performed
with brine and scCO₂ at 8.3 MPa (1200 psi)...
