Re: Methods to Place GENER Block Nicholas, PetraSim can help you prepare a TOUGH input file including the proper location of production/reinjection wells in the conceptual model and then in the discretization grid. Alfredo

Re: Run ends early Nicholas, You should check why the simulation is not converging, looking at messages, at the element causing the non convergence and at its thermodynamic state,…

Re: Run ends early Hi Nicholas. From your mesh file it seems you are using a single horizontal layer (NZ=1). The infile reports initial conditions only for the injection element: P=5.86E6 Pa, T=12°C and Xair=0.…

Re: Defining Tortuosity You should run the first segment without diffusion. Then run a restart by assigning the desired diffusion parameters.

Re: Defining Tortuosity I have to correct my self. I made a wrong check in PetraSim: actually the code accepts negative diffusivities. Thus, even the third TOUGH2 option mentioned in the previous post can be chosen in…

Re: Defining Tortuosity Hi Abdelrazik. TOUGH2 allows 3 options for assigning the tortuosity coefficient and the the diffusivities used to compute the diffusion fluxes (see pag. 159 of the User's guide).…

Re: Facing problem to match TOUGH output with excel and Python I noticed the following: * the thermal diffusivity for the given parameters seems to be 3.368E-6 m2/s, not the stated 1.28E-4 m2/s. * you want to inject heat at 30 W/m2.…

Re: ECO2N / ECO2M: handling of wettability in a dry zone Hi Godarzi. When dry CO2, or any other dry gas, is injected in a medium containing water, water is evaporated according to local thermodynamic equilibrium eventually promoting the complete…

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: 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…
