CO2/Water Displacement in Porous Medium Under Pressure and Temperature Conditions for Geological Storage

AbstractThis paper presented CO2 injected into water saturated porous media for immiscible displacement using high-resolution MRI. The porous medium was formed from the packed bed of glass beads 0.2mm. CO2/water displacement processes were implemented by a spin echo sequence with MRI technique. CO2/water displacement process was investigated for different flow rates. Then CO2 and water distribution were distinguished from MRI images. Then residual water saturation were obtained at steady state. The effects of capillary number were investigated. The study provides useful data for transport process in CO2 storage
