Re: T2Well constant fluid properties and EOS1 relationship? Dear Hannah, if I understood properly your question, you would like to have a variable P boundary, with P varying in time according to some constraint specific of your simulated problem.…

Re: T2Well constant fluid properties and EOS1 relationship? Dear Hanna, fluid properties will be computed according to local conditions by the EOS (EOS1 in your case) in all grid elements, either belonging to reservoir or wellbore.…

Re: T2Well constant fluid properties and EOS1 relationship? Dear Hanna, the parameters listed under ROCKS block are related to wellbore discretization elements, not to the fluid flowing within the wellbore. Fluid properties are computed according to the…

Re: bugs or misunderstanding? Dear Jian, about your comments related to T2VOC: 1) simply at the time the density of aqueous phase was not added to the printout. Of course it is not a bug: adding Daq printout would be very easy.…

Re: EOS7 - Brine Definition & Tracing flow of brines I think you have to consider the intrinsic limitations of EOS7 approach to model a brine of variable salinity. Strong evaporation processes may increase the brine fraction Xb over 1,…

Re: EOS7 - Brine Definition & Tracing flow of brines As stated by the TOUGH2 user's guide "EOS7 represents the aqueous phase as a mixture of (pure) water and brine". In practice the aqueous phase is a mixture of a reference brine (with mass fraction…

Re: T2Well-ECO2N @Godarzi K Dear Godarzi, T2Well-ECO2M has been coded by Lehua Pan at LBNL, but it is still at a research code level. I think it is for this reason the code is not yet available for commercial…

Re: T2Well-ECO2N 1) JT effects: they are implicitely modeled by ECO2M and ECO2N thanks to the dependency of enthalpy on P&T. So, a depressurization of CO2-rich phase will involve a cooling,…

Re: T2Well-ECO2N Dear Godarzi, if you are interested primarily to simulate fast transients at well start-up or shut-in, then you definetely have to use T2Well. For pure CO2 injection in saline aquifers with T<100°C…

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…
