For investigating the wellbore flow process in CO 2  injection scenarios, coupled wellbore-reservoir (WR) and conventional equivalent porous media (EPM) models were compared with each other. In WR model, during the injection, conditions for the wellbore including pressure and temperature were dynamically changed from the initial pressure (7.45–8.33 MPa) and temperature (52.0–55.9°C) of the storage formation. After 3.35 days, the wellbore flow reached the steady state with adiabatic condition; temperature linearly increased from the well-head (35°C) to the well-bottom (52°C). In contrast, the EPM model neglecting the wellbore process revealed that CO 2  temperature was consistently 35°C at the screen interval. Differences in temperature from WR and EPM models resulted in density contrast of CO 2  that entered the storage formation (~200 and ~600 kg/m 3 , resp.). Subsequently, the WR model causing greater density difference between CO 2  and brine revealed more vertical CO 2  migration and counterflow of brine and also developed the localized salt-precipitation. Finally, a series of sensitivity analyses for the WR model was conducted to assess how the injection conditions influenced interplay between flow system and the localized salt-precipitation in the storage formation.
