| Session Description | The mitigation of carbon dioxide (CO2) emissions has become one of big issues in the world. Subsurface storage and utilization of captured anthropogenic CO2 (CCUS) provides a promising technology to decrease the rate of increase of CO2 in the atmosphere. The CCUS is characterized as an interdisciplinary R&D technology in energy geosciences between the basic science (geology, geophysics and geochemistry) and the reservoir engineering (site selection, reservoir geomechanics and potential evaluation). This session focuses on the fundamental aspects of understanding the fate of CO2 injected into deep reservoirs, the multi-physical, biogeochemical, and coupled interactions among CO2-brines, minerals, and hydrocarbons, and utilization strategies of CO2 in the subsurface (e.g. enhanced geothermal system, subsurface energy storage, and unconventional resources recovery by CO2). This session also welcomes innovated investigations of monitoring technologies and leakage risks associated with fault reactivation and seal remediation during the large-scale sequestration and utilization of CO2. |
