The workflow from experiment to digital data analysis. The black solid arrows are used to relate the tasks and milestones in Phase I. The blue and green arrows (in Phase II) show a path that the pre-treatment and post-treatment sample, respectively take and the red arrows (in Phase III) refer to data flow. The dashed arrow (in Phase II) illustrates a path that the sample follows in the course of saturation with brine, injection of polymer-gel solution, and drying in oven.
