AB Fluid transport in petroleum reservoirs occurs on at a wide range of scales that involve multiple physics. Flow simulation with respect to all scales and interactions with the solid phase is computationally expensive, if not impossible. The recently developed Multiscale Multiphysic Mixed Geomechanical Model (M3GM) overcomes this deficiency with respect to porous media deformation. However, its application to practical problems requires extensions that enable it to deal with surrounding strata and actual geomechanical boundary conditions. This paper discusses first the combination of multiscale finite-volume (MSFV) and finite-element frameworks for simulation of fluid transport and soil deformation. Then it describes the interaction of multiphase flow and solid deformation using an iterative sequential strategy. Next the effect of surrounding rock is simulated in the M3GM with virtual springs. Finally the Multiscale Multiphysic Mixed Geomechanical Model with Surrounding Rock is presented. A new method, the treated dual-volume boundary condition (TDVBC), is employed to better incorporate Dirichlet boundary conditions. Indicative test cases are analyzed and reasonable results with high computational efficiency are achieved.
