Convective-reactive transport of dissolved CO2 in fractured-geological formations

Carbon dioxide (CO2) storage in geologic formations is an attractive means of reducing greenhouse gas emissions. The main processes controlling the migration CO2 geological are related to convective mixing and geochemical reactions. effects heterogeneity on these coupled have been widely discussed literature. Recently, special attention has devoted fractured that can be found several reservoirs. However, existing studies effect fractures fate neglect key This work aims at addressing this gap. Based numerical simulations a hypothetical reservoir, we explore fracture properties topology domain's capacity different rates mineral dissolution. It not only help convection reaction process domain but also may play restrictive role entering dissolved hinder plume fingers from growing. case relevant providing preliminary understanding show varying degrees realism. For more representative geology, investigate migration-dissolution buoyant large-scale outcrop volcanic basalt rock formation. results neglecting thin significantly affect predicted amount trapped CO2. sensitive low dissolution rates. findings useful for management sequestration domains.
