CT dataset of flow experiments in Phohang Sandstone (Part 1 of 2)

This dataset contains synchrotron-based X-ray micro-computed tomography (μCT) images of a heterogeneous sandstone core during drainage, where supercritical CO2 was injected into brine-saturated pore space under reservoir conditions. The sample (4 mm diameter × 10 mm length) was scanned at the 6C beamline of the Pohang Light Source-II (PLS-II), using a monochromatic X-ray beam of 34 keV. These μCT datasets can be used for pore-scale analysis of CO2–brine multiphase flow in heterogeneous porous media. The uploaded files are divided into Part 1 and Part 2 due to file size limitations.
