Data for: Formation of common preferential two-phase displacement pathways in porous media

With the use of optical microscopy, microfluidic experiments took place in quasi-2D artificial porous media for a variety of cyclic displacement processes and boundary conditions, four of which are shared here. This Dataset contains the data presented in the related publication Vahid Dastjerdi et. al. (2024). <br><br> Each experiment is flow-controlled and has a different flow rate. Three of the experiments include 12, 21, or 24 sequential displacement events. The images and pressures recorded during the experiments are presented. Due to some technical issues, pressure values for experiment 2 are not available.
