abstract = {<p style="text-align: justify;">This paper presents numerical results on the development of compositional fluid
mixing simulators in porous media. These simulators integrate geological processes (source rock
maturation, hydrocarbon generation, migration, charge/filling, etc.) and reservoir processes (fluid mixing through Darcy&#39;s flow, advection, and diffusion, gravity segregation, etc.). The model
governing equations are written with a proper choice of solution variables so that numerical mass
conservation is preserved for all chemical components. The approximation procedure uses the finite volume method for space discretization, the backward Euler scheme in time, and an adaptive
time stepping technique. The traditional simulator for solving the isothermal gravity/chemical
equilibrium problem is deduced as a special example of the simulators presented here. Extensive
numerical experiments are given to show segregation and instability effects for multiple components.</p>},
