IFP Energies nouvelles has organized the LowPerm2015 conference held as part of its Rencontres scientifiques series of events in Rueil-Malmaison, near Paris (France), on
Tuesday 9, Wednesday 10 and Thursday 11 June 2015.
LowPerm2015 aimed to serve as a platform for exchange and interaction between research and industry players from a variety of different disciplines working on the characterisation and modelling of low to very-low permeability media and nanoporous materials.
Media of this type are found in a broad range of scientific and technical fields, such as geological formations (shale, tight sandstone or carbonates, etc.), concrete engineering, polymer sheaths for pipelines, nanofiltration for produced water treatment, heterogeneous catalysis, etc.
These very different applications all face the same challenges: the characterisation and modelling of these media and materials and the associated transport mechanisms at different scales.
Characterisation starts with a description of the properties of these very specific porous media at pore scale (absolute permeability, pore size distribution, microfracture density, specific surface area, texture, etc.) using cutting-edge measurement and imaging techniques (synchotron radiation, FIB, microtomography, etc.).
Another issue is understanding the fluid transport mechanisms at work inside low permeability media and nanoporous materials at pore scale. This requires theoretical and experimental studies of competing physicochemical, chemical and flow processes, potentially reinforced by confinement: adsorption, desorption, diffusion, reactive multiphase flow, in particular. It is also very important to gain greater knowledge of the macroscopic properties of these media and materials, which frequently exhibit significant heterogeneities at different scales. This requires accurate assessment of the nature of the heterogeneity at large scale, as well as its impact on fluid flows and transport. Upscaling of physicochemical properties and constitutive laws is one of the essential keys for bridging the gap between pore and macroscopic scales, warranting dedicated homogenisation techniques.
The conference program included cross-disciplinary sessions aimed at shedding light on recent breakthroughs concerning theoretical results, advanced experimental devices and methodologies, modelling approaches and case studies.
Geoscientists, petrophysicists, physicists, thermodynamic experts, chemists, polymer researchers, catalysis specialists… have taken the opportunity to participate in this major event bringing together a variety of disciplines dealing with low-permeability media and nanoporous materials!
