Replication Data for: Comparison of four competing invasion percolation models for gas flow in porous media

This dataset includes processed gas injection images obtained at the end of nine gas-injection experiments to support the analysis presented in \"Comparison of Four Competing Invasion Percolation Models for Gas Flow in Porous Media\". Images are presented as processed binary saturations (Matlab file format .mat), following post-processing quality assurance and Light Transmission Method (LTM) conversion. The naming of the images corresponds to the name of the gas-injection experiments described in Van De Ven and Mumford (2019) Characterization of gas injection flow patterns subject to gravity and viscous forces, Vadose Zone Journal, 18, 190014, doi:10.2136/vzj2019.02.0014.
