Multiphase flow and fault poromechanics : understanding earthquake triggering and seismic hazard

In this Thesis, we investigate natural and engineered processes related to the assessment of the seismic hazard from the impact of anthropogenic operations on the stability of pre-existing geological faults. We do so by developing simulation tools that coupled multiphase flow and geomechanics, and apply them at the field scale using geologically realistic representations of the subsurface. In a first contribution at the scale of individual fractures, we study the impact of confining stress on the capillary pressure behavior during drainage through rough fractures, where we find that capillary pressure variations are sensitive to the degree of confining stress and the degree of spatial correlation of the fracture aperture.
