Re: Can TOUGH3 EOS7C model temperature below 13 celsius degree?

Jianhua, Yes, EOS7C has a lower limit of 12 C in its solubility model because this is a region where CO2 or CH4 hydrates could start to form, depending on pressure of course.…

Re: How to inject CO2 using eos2

Dear Shohei, I think the problem may be that your specification of enthalpy of injected water and CO2 become inaccurate as the injection occurs because the heat capacity of water and CO2 change as…

Re: assigning the right enthalpy

Assigning enthalpy to an injectate to achieve a desired injection temperature is not generally possible because the process of injection can change P-T conditions which then change effective heat…
