How to simulate mixed gas injection with Toughreact v1.2
I am trying to develop a model that is used to simulate a mixed gas to inject into a formation, and then get a gas-water- rock reaction model.
The mixed gas includes CO2 and H2S and H2.
which eos should I use? eos 3? I am not sure.
Now, I am using eos3, and I add an extra cell where the air mass fraction equals 1.
In the extra cell, a gas zone including CO2, H2S, and H2 is set.
However, I can not get a low pH in the cell that connects with the extra cell.
I have no idea what the problem.
According to the conceptual model, the cell connected with the extra cell should have a low pH because the extra cell is a large volume of mixed acid gas.
So, do you have any suggestions?
Thank you so much.
