Porestructure Level Modeling of Porous Media and its Relation to Macroscopic Modeling

10:30 AM-12:30 PM
Room: Executive Salon 3

Simulation of flows in porous media is central to both reservoir modeling and environmental science. This minisymposium will provide an insight into current trends in modeling at different length scales, as well as in three-dimensional numerical simulation of porous media flow. The speakers in this minisymposium will examine modeling at different scales and the computational challenges of simulating three-dimensional flows. At the pore-scale level, one promising approach is a stochastic analysis of the geometry of the pore and grain phases; another accounts for the effects of pore-scale interfacial phenomena and derives a new macroscopic model involving the average interfacial area. At a different scale, stochastic modeling of properties of adsorption sites gives improved results over standard hydrodynamic dispersion models. Two perspectives on three-dimensional numerical simulations are presented, one on three-dimensional simulation of reservoir properties, and the other involving a new three-dimensional parallel algorithm for solving the pressure equation for porous media flows.
