Abstract
Interaction of fluid such as CO2 with the host rock in the subsurface is of primary importance to evaluate the seismic hazard related to injection of fluids at depth. However, the role of fluid pressure in fault stability poses challenges in our understanding of seismic events. I will provide an overview of mathematical models describing flow and mechanics in the presence of fractures. The mixed dimensional, multiphysics model takes into account friction and normal forces including the effect of the fluid pressure. Using the tools of mathematics of contact mechanics, we analyse the mathematical model.
Moreover, we develop and analyse temporal and spatial discretizations for numerically solving the governing equations. This is a joint work with
Maarten de Hoop (Rice University),
Mircea Sofonea (Perpignon),
Omar Duran (Bergen), Solveig Stefansdottir (Bergen),
Mary Wheeler (Austin), and Vivette Girault (Paris).
