Cecile specialises in fracture systems analysis in geothermally- and tectonically-active areas. She investigates the relationship between fractures, stress and fluid flow using downhole measurements and outcrop analogues.

Cécile and Muriel will develop computer models that represent how deep rocks deform under the pulling of the tectonic plates. This will help identifying the conditions in which cracks form near the BDT. The models will be linked to the other models of fluid and heat flow that in turn affect how the rocks deform. They will create 3-D elasto-visco-plastic reservoir-scale geomechanical models of rock deformation near the BDT tailored to the Taupo Rift tectonic settings and host rocks. Two-way coupling to reservoir-scale heat/flow simulations willconstrain the evolution of permeability near the BDT as a function of rheology, thermal and stress states, and lithologies. These reservoir-scale models will enable dynamic mapping of superhot hydrothermal fluids at the BDT.
