Viscous fingering pattern (left) observed when air is injected fast in a porous medium previously filled with a viscous liquid (dark gray). The image analysis (left) shows the time (image number) of injection of each pore and can be used to analyze the relative probability of pore invasion events.

The investigation of porous media flows is a topic of pivotal importance for several aspects of human activity. The extraction of water from natural reservoirs and the recovery of oil from subsea rocks are two examples where the knowledge of porous media physics brings immediate economical and societal impact. Since the visualization of flows in porous media can be very challenging, numerical simulations have been used to study the morphology and dynamics of flow structures both in fast and slow injection processes. By employing numerical simulations, Furuberg et al. have addressed the interesting question of how the invasion probability of sites in a porous network varies with space and time. With the development of modern high-resolution imaging techniques, we can now address this question also experimentally. In this project we will investigate, both experimentally and analytically, how the pore invasion probability depends on several parameters of the flow (velocity of injection, geometry of the sample, gravitational effects etc.)
