Fracture networks exist at a wide range of scale in the earth crust and strongly influence the hydraulic behavior of rocks, providing either pathways or barriers for fluid flow. Many oil, gas, geothermal and water supply reservoirs form in fractured rocks. Naturally fractured reservoirs also represent a significant geological storage potential for CO2. Since the 1990s there
has been an increasing interest towards Carbon Capture and Storage (CCS) techniques to mitigate the world greenhouse gas emission. In this context, modeling and simulation of CO2 flow in fractured systems is crucially important for CO2 storage location selection and risk evaluation: for
example, the study of upward leakage potential, due to CO2 buoyancy, must be considered in any extensive study of sequestration sites. The main challenge is the development of numerical models
that describe adequately geometry, spatial distribution and constitutive equations governing the physical process in fractured reservoir, with the integration of field observations to calibrate, verify
and validate the model. Presentations are invited to cover researches related to field investigations, analogue models,
numerical models of fluid flow in fractured media for case studies in the characterization and assessment of naturally fractured reservoir for CO2 sequestration.
