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.

Foam rheology in porous media

For processes involving gas injection, such as enhanced oil recovery (EORa) and CO2 storage operations, the use of foam makes it easier to control gas mobility. Improving these processes requires
