Variations in Permeability and Mechanical Properties of Basaltic Rocks Induced by Carbon Mineralization

Carbon capture, utilization, and storage (CCUS/CCS) is a strategic choice for ensuring energy security reducing carbon dioxide emissions across the globe. The injection of CO2 into basaltic reservoir one strategy permanent disposal emissions. Basaltic rocks, which are widely distributed in Hainan Island, capable geological sequestration. In this study, reaction CO2-NaOH/Ca(OH)2-basaltic rocks under conditions 6.0 M Pa 30 °C was performed using samples collected from Fushan area Province to evaluate sequestration basalt by mineralization. Then, effect mineralization on permeability mechanical properties evaluated X-ray computer tomography triaxial compression testing at 21.0 MPa. addition, microwave technology used irradiate before Changes after irradiation were simulated numerically, their effects strength deterioration analyzed according rock mechanics testing. Based these results, new method induction deterioration, mineralization, injectivity, capacity proposed use CCUS/CCS engineering.
