Re: How to set a production well with constant pressure @selin dai what I see is that you start with a tiny time step and convergence is achieved at the first iteration. Thus, with no changes of primary variables.…

Re: How to set a production well with constant pressure Brad, I think a rigorous approach would require the use of a coupled wellbore-reservoir flow solution, like that avaialable in T2Well. I'm not aware if something similar is available in TOUGH+.…

Re: How to set a production well with constant pressure Actually, TOUGH2/3 and I think TOUGH+ too, could use virtual elements (like those with infinite volume) connected to any element of the discretization grid.…

Re: applying heat load in BHE and varying input T? I guess you should remove the inactive cell at DHE input and use GENER to inject your variable fluid rate history by assigning the injection enthalpy corresponding to your desired inlet T vs time.…

Re: applying heat load in BHE and varying input T? Dear Hanna, I understood you want to apply a heat load to your entire BHE. But you applied the heat load by just injecting heat into the BHE inlet (eleme A1000).…

Re: CHEMP block for diesel and gasoline? Mikey, as diesel fuel and gasoline are complex HC mixtures, if you want to simulate approximately their thermodynamic behaviour you might use a pseudo-component approach as customary made in the O&G…

Re: Pressure vs CO2 DG Jose, if you are using T2Well, it would probably mean that domain belongs to a wellbore section for which you want the calculation of wellbore heat exchange using the analytical formulation by Ramey.…

Re: Efficient time stepping with great variability in pumping/shutin period durations Yannick, I would try using the actual pumping history with MOP(12) =2. In this way you should at least replicate the cumulative production during each time step.…

Re: Pressure reporting: Tgh2-ECO2M Godarzi, I need to clarify my previous post. The ECOM version I used is V.2 by Lehua Pan which can simulate H2O-CO2-NaCl mixtures up to 300°C. It seems it is not able to accept the ECO2N style INCON…

Re: Pressure reporting: Tgh2-ECO2M Hi Godarzi. I tried your input file with T2Well-ECO2M, of course with no wellbore flow. The P vs log(radius) at 1 year is shown below. In your input file I noticed that you have omitted the phase…

Re: Can TOUGH3 model temperature below zero degree? As reminded by Christine, TOUGH2/3 cannot handle T below the triple point of water, as 0.01°C is the lower limit for the old IFC67 and the new IAPWS-IF97 correlations for the properties of water and…
