Numerical Analysis of Storage Potentials for CO2 Micro-bubble Storage (CMS)

AbstractFor geological storage, as the small-scale distributed emission systems, CO2 micro-bubble storage (CMS) system may be suitable. To validate the feasibility of the CMS system, a numerical analysis was carried out. For the injection method and the targeted depth defined above, a unit comprising an injection well and four water pumping wells was modeled, The study showed a possibility of stable storage of CO2 in solution under the conditions of temperature, pressure and water chemistry at depths of 300 to 500 m, as long as full dissolution of CO2 gas with micro-bubbles is ensured
