Capillary and viscous fracturing during drainage in porous media

Detailed understanding of the couplings between fluid flow and solid deformation in porous media is crucial for development novel technologies relating to a wide range geological biological processes. A particularly challenging phenomenon that emerges from these transition invasion fracturing during multiphase flow. Previous studies have shown this highly sensitive rate, capillarity, structural properties medium. However, comprehensive characterization relevant material failure regimes does not exist. Here, we used our newly developed Multiphase Darcy-Brinkman-Biot framework examine drainage viscously-stable soft broad flow, wettability, rheology conditions. We demonstrate existence three distinct controlled by non-dimensional numbers quantify balance viscous, capillary, forces
