This paper presents a code comparison of coupled multiphase flow and geomechanical processes resulting from CO2 injection into deep saline formations. The coupled simulator OpenGeoSys-Eclipse as well as Eclipse-Visage, GEM and OpenGeoSys are used for this purpose. Comparison of the results of the different simulators shows a strong dependence of the results on the grid discretization and the numerical methods applied. Further investigations of the one-way coupled geomechanical simulations shows that even if the multiphase flow results are nearly identical for the simulators used, the geomechanical response on the pressure build up can be different.
