Porous media have in common to develop a large interface that divides the space with a varying degree of complexity, potentially with hierarchical structuring. Such environments are central to IFPEN’s research on geological formations and certain industrial materials.
The thermodynamic, dynamic and rheological properties of the fluids present in the porous network are strongly influenced by the nature of interfacial interactions (wettability and adsorption) and by the degree of confinement of the pore space. This dual dependency makes it possible to cover a rich phenomenology of behaviors associated with molecular adsorption, thermodynamic phase diagrams, micro or even nanorheology of confined fluids, more or less complex (foams, emulsions, etc.), and with their transport and reactivity. For the latter field, searching optimized reaction conditions remains a real challenge.
This issue presents recent research in this rich and dynamic field, in which the dual top-down and bottom-up approach is very promising for crossing time and space scales, from macroscopic through to nanocontainment, a research area still full of surprises.

In many geological reservoirs, pore size distribution is highly heterogeneous (from 2 to 50 nm).
What percentage of free compounds in porous media?
The energy mix required to satisfy global needs will include fossil hydrocarbons for some time to come.
Adsorption, a key factor for geological storage
Low permeability geological layers, already known within the context of oil exploration, are once again becoming a focus of interest for energy (co
