Gas Migration

Multiple gases migration in soil and rock materials can be simulated. Generation of aerobic/anaerobic gas (methane, hydrogen, etc.) in the industrial waste repository or leakage of urban gas from embedded pipelines is one of the typical scenarios for the simulations. Formulation of gas migration is based on the generalized Darcy’s law including mass transfer between phases (gas dissolution to water phase, degases, etc.) and pressure-dependent pore deformation. For the visualization of gas pathway, the advection-dispersion simulation of chemical species is also available. Output data which can be extracted from simulation is saturation of each fluid phase, mass concentration of species, pressure, potential, velocity, etc.
