New porous microstructure descriptors based on tortuosity and accessibility

IFP Energies nouvelles has developed new morphological descriptors for porous networks. The result of work carried out in partnership by two of its research divisions, they are hinged around the concepts of accessibility and tortuosity to describe paths within a material.

Phase equilibria in confined media
In many geological reservoirs, pore size distribution is highly heterogeneous (from 2 to 50 nm). While the molecular size of the confined fluids is between 0.5 and 10 nm, their interaction forces with
