    I made some more revisions.I modeled and simulated the injection of CO₂ fluid at a depth of 1.475 km with an injection rate of 3.7 kg/s. After injection, the CO₂ migrates both laterally and vertically, but I encountered the following errors when running TOUGH2-ECO2M. Can anyone help me? I really need some suggestions.
