Re: T2Well-ECO2N
Dear Godarzi, T2Well-ECO2N allows simulating the coupled wellbore-reservoir flow. Of course, while 1D flow is modeled along the wellbore, the reservoir can be discretised as usually made for…

Re: Temperature limit
Dear Antonio, TMVOC in TOUGH2 uses the IFC-67 correlations for pure water properties. I guess TMVOC in TOUGH3 uses IAPWS-IF97. In both cases, Region 1 correlations (liquid water) have an upper limit…

Re: Grid orientation effects on mineral dissolution
Ozawa, it seems you are running TOUGHREACT under Petrasim. Have you tried to use a Voronoi grid ("Polygonal" in Petrasim) instead of a cartesian one? You can also try to force Petrasim to build a…

Re: methane leak and plume migration in subsurface from hydrocarbon wellbores
Alireza, TMVOC V.1.0 (Pruess and Battistelli, 2002) can model a mixture of water and CH4, but CH4 has to be included as an NCG, not a VOC because its critical temperature is lower than subsurface T…

Re: methane leak and plume migration in subsurface from hydrocarbon wellbores
Hi Alireza. The user's guide of EOS7C V.1.0 does not mention the possibility to simulate gas adsorption. Other TOUGH2 modules or codes simulating gas adsorption are: - EOS7C-ECBM : Webb S.W. (2011).…

Re: Calculating flow rate in a well on deliverability model
Dear Alborz, looking at your grid and at the "wellbore" P and porous medium P, it seems you are actually modeling a trench to be used for soil gas extraction.…

Re: TOUGH+RealGasBrine for CO2 injection

Re: Ask : MP function at petrasim 2018
The Petrasim package does not include the executables for TOUGH2-MP. They need to be purchased through LBNL.

Re: How to apply this unique Mix of Neuman + Dirichlet Boundary conditions, for Temperature & Pressure, 1-d Problem
@Mikey Hannon a. Fluid exiting the system cannot be avoided, as it is a consequence of the constant P boundary condition. b. Using a short node distance from the interface for the inactive element…

Re: How to apply this unique Mix of Neuman + Dirichlet Boundary conditions, for Temperature & Pressure, 1-d Problem
@Mikey Hannon Sure, flow would not be inhibited through the right boundary. If fluid flux is going outside of the system with no conduction, the BC for T should be close to Neuman.…
