Re: Help deciding EOS7C or EOS7CA
@Jordon Massey I think EOS7C should give rather accurate thermodynamic equilibria and thermophysical properties of gas and aqueous phases at near surface conditions too.…

Re: Help deciding EOS7C or EOS7CA
Jordon, Have you considered to use TMVOC under Petrasim? It can handle mixtures of CH4 and air with a thermodynamic description suitable for low pressure conditions. Alfredo

Re: Printout problem with TIMES
OK. This seems to be a different question, but I'm not sure to have understood what you would like to have. I think TIMES lets you specify at which simulation times the code shall make a printout.…

Re: Printout problem with TIMES
I think TOUGH2 is doing what it should do. FOFT controls the printout of a fixed number of parameters at each time step for the listed elements. TIMES controls the printout of main output tables.…

Re: Modelling of high temperature (600 ℃) air injection.
Dear Xin, you posted in the TOUGH2 section, so I assume you are using TOUGH2. No standard TOUGH2 module can go above 350°C, which is the limit of liquid water properties of Region 1 in the IAPWS P-T…

Re: CO2 storage in saline aquifer with ECO2N
I guess you could compute for each grid element belonging to the rock domains affected by CO2 migration: mass of dissolved CO2: MCO2w = V phi (1. - SG) DL XCO2aq CO2 mass in the gas (NA) phase:…

Re: About the SEED with porosity
Hi Luoluo. SEED allows to use permeability modifiers only. A similar option is not available for porosity. But you should be able to assign element by element porosity values (PORX) just using the…

Re: TOUGHREACT1.2/ECO2N: About the inject rate and maximum pressure
You are using a 2D vertical slice just 1 m wide. Injecting 5 kg/s CO2 in a vertical slice is not comparable to inject the same rate in a radial system. I think you should either use a radial grid or…

Re: TOUGHREACT1.2/ECO2N: About the inject rate and maximum pressure
Your output file does not show any problem for the 30 days simulated. The P builds up to 596.33 bara, as you mention, for a relatively limited injection rate of 5 kg/s.…

Re: T2WELL deals with time scale inconsistencies
Mass balance eqs for reservoir and wellbore elements are assembled and solved together by T2Well within each time step. Thus, fast transients occurring in the wellbore grid elements control the…

Re: Simulated CO2 injection into aquifers using T2WELL/ECO2M did not run successfully

Re: Simulated CO2 injection into aquifers using T2WELL/ECO2M did not run successfully
It is difficult to understand what it is not going on properly. I just noticed that the injection element reaches a low negative temperature of -17.96°C at about 20.4 bar.…

Re: Can TOUGHREACT automatically calculate injection rate into each element?
Not sure it can work. What is needed is something to emulate the injection wellbore. A column of elements shall be added and connected to the injection elements.…
