Abstract: 

Several porous media are characterized by a network of nanopores where the adsorbed fluid lies in a anomalous state subject to strong intermolecular forces with the solid particles. Among them we may highlight, shale gas, coalbed methane and swelling clays.

Understanding the role of such a complex nanoscopic phenomenon, coupling with geomechanics and upscale to the macroscale, passing through the intermediate scales associated with the presence of mesopores, natural and hydraulic fractures, remains a challenging issue. In this talk we propose a new methodology to tackle this problem which combines Thermodynamics of Confined Fluids with formal Homogenization methods and Discrete Fracture Modeling (DFM). Numerical simulations illustrate the enormous potential of the approach in capturing precisely the influence of the nanopores upon the effective medium response.
