Soil and rock underneath the ground surface are heterogeneous materials where fractures play an important role. Fractures are key flow pathways that dominate fluids migration and solute transport in reservoirs. Due to geochemical reactions, they can be enlarged or sealed, and their geometry varies depending on a number of factors including the flow regime, the fluids composition, the mass
transfer between the fracture and the matrix, and the alteration of mechanical properties. The objective of the FraMatI project is to improve our fundamental knowledge of fractures alteration and to develop predictive capabilities of reactive multi-phase flow in complex geological formations in order to assess the long-term effectiveness and the environmental impact of anthropogenic subsurface activities. The scientific strategy relies on a systematic multi-scale analysis of the fracture-matrix interactions starting at the micro-scale by means of numerical modeling and microfluidic experiments.
