Data for: Experimental Evaluation of Connectivity in Two-phase Flow in Porous Media during Drainage

With the use of optical microscopy, microfluidic experiments take place in quasi-2D artificial porous media for a variety of cyclic displacement processes and boundary conditions, three of which are shared here. This dataset contains the data presented in the related publication by Vahid Dastjerdi et. al. (2022). Each experiment is flow controlled and has a different flow rate and includes 12 sequential displacement processes. The microfluidic cell is first saturated with the wetting phase (water in the presented experiments). Displacing the water with Fluorinert (the nonwetting phase) forms the primary drainage event. Main imbibition, main drainage, and 9 scanning events proceed by injecting water and Fluorinert sequentially. The images and the pressures recorded during the experiments are presented.
