A virtual porous media can be created from two different methods:

Validation of Results from Virtual Packing of Spheres

Simulator was modified to reduce the porosity to lower values by putting new grains to empty spaces of original generated pattern.

First principle calculations (e.g, Navier-Stokes, Maxwell, etc) are used to derive properties such as:

Sand pack from actual set of images. However in this case we synthetically created more grains in each 2D cross-section in order to decrease its porosity and evaluate Archie exponent shown in the below.

F = A “φ” ^(-m) for different φ, gives m≅1.7

Oil-Water system resulting from addition of the different components.

NMR spectra Fully saturated with water (blue) Fully saturated with oil (black)

Porous media saturated if water (blue) and oil (black)

BUT FIRST IT NEEDS TO BE TESTED WITH LIQUIDS

FOR GASEOUS SOLVENT MRI IS MORE APPROPRIATE

FOR LIQUID SOLVENTS CT IS MORE THAN ADEQUATE

Oil concentration profiles at different mixing times

Solving equations of flow and transport:

Simulations are being conducted at various flow conditions:

Mixing zone growth rate ( σ ) at different flow conditions:

K_L in a porous media along the flow direction can be calculated by matching the numerically obtained concentration profile at the outlet with the analytical semi-infinite solution of convection-dispersion equation.

At macro-scale, longitudinal dispersion can be described by a convection-dispersion equation:

What is the thickness of condensate?

What can we do when images are not available?

How about when we want quick and dirty results?

How about when we have limited computer capabilities?
