Subsurface flow of CO2 through saline and hydrocarbon reservoirs exhibits distinct phase behaviour, chemical reactivity, and petrophysical flow properties relative to other systems that have been extensively studied in the fields of petroleum engineering, groundwater hydrology, and contaminant transport. Experimental investigations are critical for the development of accurate simulations of CO2 flow and trapping in the subsurface. In this session, we seek contributions from investigations of the most pressing issues in the geologic storage of CO2 that are either conducted as a pure experimental or as a combined experimental/modelling study. Topics of interest include the following:
• (Multiphase) flow properties of CO2/brine/hydrocarbon systems in porous and fractured media.
• Fluid transport processes in tight lithologies (coupling between processes, i.e. viscous flow vs. diffusion; pure capillary controled flow vs. dilatancy induced flow)
• Interfacial properties of CO2/brine/hydrocarbon/rock systems.
• Phase properties of CO2/brine/hydrocarbon systems.
• Geochemical processes and their impact on flow, phase behaviour, and storage security.
• Impact of CO2/fluid/rock interactions on rock mechanical properties
• Bridging scales from the pore to the Darcy to the basin scale.
• The impact of heterogeneity on flow and transport in geologic CO2 storage.
• Experimental parameterization and validation of models of flow and reactive transport for geologic CO2 storage.
• The use of analogue fluids and temperature/pressure conditions to study geologic CO2 storage.
• Studies from natural analogues for the storage of CO2 to investigate the long-term fate of CO2 in the subsurface.
• Novel experimental techniques for the observation of rock properties, flow, geochemical reaction, and transport for geologic CO2 storage.
