Title:
MS36
Advanced numerical methods in subsurface flow simulations in discrete fracture networks • Part II
Type:
Subsurface models (cryoshpere, hydrosphere, lithosphere, pedoshpere)
Room:

In several applications related to subsurface exploitation (geothermal applications, geological storage, enhanced oil & gas production...), the underground medium is frequently described by the Discrete Fracture Network (DFN) model, in order to properly account for the directionality of the flow in fractured media. Within the DFN model the fractures are explicitly described, and the flow mainly occurs along the fractures and their intersections. Issues in numerical simulations in DFNs are typically related to: the flow model, the coupling with the surrounding rock matrix, the geometrical complexity of the domain, and the uncertainty both in the hydro-geological and in the geometrical parameters describing the fractures. Recent advances in numerical methods related to these issues will be the primary topic of the minisymposium.
