Title:
MS4
CO2-Hydrocarbon interactions for CO2 storage with EOR/EGR
Type:
Subsurface models (cryoshpere, hydrosphere, lithosphere, pedoshpere)

Storage of carbon dioxide (CO2) in geological formations is a means to reduce atmospheric emissions of this greenhouse gas. CO2 storage combined with enhanced oil recovery (EOR) or enhanced gas recovery (EGR) is perceived as the most cost-effective method of disposing captured CO2 emissions. CO2-EOR has been performed for many decades with a focus on hydrocarbon recovery. With CCUS, CO2 storage will be emphasized in order to meet CO2 emissions targets.  Interactions of CO2 with in-situ fluids and the host rock could fundamentally alter the ability to recover trapped hydrocarbons while simultaneously affecting CO2 storage potential. This minisymposium focuses on two relevant processes, convective mixing and wettability alteration, along with their analytical and numerical solution strategies. Density-driven convective mixing of CO2 in oil increases mixing and alters the oil mobility. Wettability may change dynamically with CO2 exposure, which impacts the capacity of the rock to trap CO2. Recent studies have shown compelling results that may have a significant, yet still largely unknown, impact on field-scale fluid flow (recovery) and trapping (storage).
