The main goal of the FISIC project is to provide the appropriate theoretical and numerical models for a better understanding of the hydro-chemo-mechanical behavior of fault zones under the CO2 injection conditions. The proposed scientific program aims to achieve the following objectives :
- To develop a geostatistical approach providing a statistical model for the fault zone. In this setting, different parts of a fault zone will be modeled in a “cluster” form. The advanced meshing tools will be developed for converting complex geometries to finite element models
- To design and perform specific innovative lab experiments to assess the chemical effects of the CO2 storage on the behavior of fault materials (fractured zone and gouge).
- To develop constitutive models describing the behavior of different parts of the fault zone model (fault core and damage zone)
- To develop numerical models taking into account the heterogeneous nature of the fault zone on its behavior.
