Abstract :- Geological sequestration of CO2 in porous sedimentary medium filled with saline water requires a clear view of the gas behavior as a function of topology of the hosting pores, linked to capillary phenomena. The sedimentary medium is modeled as a random packing of equal spheres giving rise to 3D network of pore bodies and throats. The injected CO2pushes the water from pores of the reservoir. The scenario is simulated by the increase of the curvature of the liquid/CO2 interface. Eventually a critical state is reached where the liquid is drained from pores. When the liquid counteracts this first drainage step (imbibition), there is a progressive decrease of the interfaces curvature until they merge together, eliminating the CO2 from pores. This pore-scale investigation of the mechanisms possibly occurring after a gas injection is studied.
