Modelling DC responses of 3D complex fracture networks

Determination of the geometrical properties of fractures plays a critical role in many engineering problems to assess the current hydrological and mechanical states of geological media and to predict their future states. Furthermore, numerical modelling of geoelectrical responses in realistic fractured media has been challenging due to the explosive computational cost imposed by the explicit discretizations of fractures at multiple length scales, which often brings about a trade-off between computational efficiency and geological realism.
