Investigation of relative flow characteristics of brine-saturated reservoir formation: A numerical study of the Hawkesbury formation

According to the results, the developed laboratory-scale model simulates the experimental results reasonably well with less than 10% relative error. The numerical results also reveal that there is a considerable effect of CO2 phase change on the final distribution of the CO2 and brine saturation profiles. In addition, the CO2 pressure distribution along the sample length shows a non-linear relationship between the CO2 pressure and sample length. According to the results of the field-scale model, the long-term interaction of CO2 causes Hawkesbury formation's pore structure to significantly change.
