Porosimetry & Two-Phase Flow


The SatuDict module deals with the distribution of two distinct fluid phases (gas or liquid) in porous materials. Saturation with these fluid phases alters the properties of the porous media, such as flow permeability, diffusivity, thermal conductivity, and electrical conductivity. These properties come to depend on the saturation of the media, and come to be considered as relative.

Depending on the distribution of the phase, saturation-dependent properties result. The relative properties are obtained by dividing the saturation-dependent properties by the properties for the entire pore space (absolute).

Examples of Applications

  • Digital Special Core Analysis (SCAL) to determine transport properties in oil and gas reservoirs.
  • Design of fuel cells materials for the automotive industry.
  • Design of personal care and hygiene materials.

Examples of Applications

SatuDict Features

The SatuDict module computes the distribution of two fluids using a pore morphology method-based algorithm known as "maximum inscribed spheres". The result of the pore morphology method is a sequence of quasi-stationary two-phase distributions, which are used in SatuDict to compute the saturation-dependent

  • capillary pressure curve.

SatuDict combined with the FlowDict, ConductoDict or DiffuDict modules allows the calculation of the following properties:

  • Effective and relative permeability
  • Relative gas diffusivity
  • Relative thermal conductivity
  • Resistivity Index / relative electrical conductivity
