Dispersive properties of porous cracked media
Authors E. M. Chesnokov, J. H. Queen, Y. A. Kukharenko, I. O. Bayuk and J. M. HooperThe method of averaging has been very effective in modeling the elastic constants of inhomogeneous anisotropic multiphase media. There are however, many, cases of interest where difficulties arise applying this approach.

Influence of the fine-scale heterogeneity patterns on large-scale behaviour of miscible transport in porous media
Authors A. M. M. Elfeki, F. M. Dekking, J. Bruining and C. KraaikampAn extensive series of numerical simulations on two-dimensional flow and miscible transport are carried out. The purpose of performing these simulations is to study the influence of fine-scale heterogeneitypatterns (i.e., horizontal laminations, cross-bedding at 45 degrees and 135 degrees) with short range and long range correlation structure on large-scale behavior of miscible transport in porous media.

Micro-scale diffusion controlled dissolution - a physical analysis of instability based on numerical modelling of dissolution patterns
Authors F. Golfier, D. Lasseux, B. Bazin and M. QuintardAcid injection in porous medium is a process widely used for stimulation of petroleum wells. Acid solution flows into the formation and reacts with the porous solid so that rock permeability increases.

A fully-implicit upscaling method for accurate representation of the balance of viscous and capillary forces
Authors K. D. Stephen and G. E. PickupIn many cases, small-scale laboratory measurements of relative permeability and capillary pressure must be upscaled carefully to obtain large-scale rock/fluid properties for accurate reservoir simulation.

On oil displacement by gas injection
Authors V. M. Entov and D. V. VoskovA two-step procedure is developed for solving 1D problems of multicomponent two-phase flow generic for EOR processes based on gas injection. First, general mathematical framework underlying this approach is presented briefly. Then its realization is illustrated by examples for 4- and 5-component systems with constant partition coefficienis and for oil displacement by CO2. Directions of future research are also discussed.

Nonlinear waves on fluid-fluid interface in porous media as the model of gas-oil fields
Authors M. Panfilov, J-M. Crolet and C. CalugaruThe new mathematical model is proposed to describe the gravity-elasastic deformations of the interface between two fluids in weakly deformable porous media. Instead of a cumbersome system of flow equations linked by the kinetica and dynamica conditions at the interface, the new model represents a system of PDE written explicitly with respect to the vertical coordinate of the interface and the interface pressure.
