EOS7C-running problem

Hi everyone, I am doing a simulation with EOS7C in the heterogeneous coal seam aquifer with water and gas extraction from the well located in the middle of the model.…

EOS7C pressure range

Hi there, I read through both the tough2 and EOS7C manuals to find the pressure range limitation to run simulations, but I didn't find it. I have a abnormal high pressure reservoir,…

Cauchy/Type III Boundary Condition

Hello, Is it possible to apply a head dependent boundary condition, where flux is a function of head difference between a cell and some prescribed value?…

Atmospheric Boundary Conditions

Hi all, I am confused with the boundary conditions that have to be imposed in an atmospheric boundary element for simulating evaporation with TOUGH2 (or TOUGHREACT). In a few slides (http://esd1.lbl.…

TOUGH 2 ECO2M temperature condition

Hi, It is described in the ECO2M user guide that TOUGH2 simulates CO2 migration under temperature condition up to 110 °C. I am wondering if the temperature condition is about 115 °C-125 °C,…

heterogeneity

Hi, i need to build an heterogenic filed (mean that kx and ky will be different in every cell). it is possible to do with TOUGH2? Thanks you, Evyatar.

production mass volume calculation

Hi there, For a constant boundary pressure, and constant production rate gas reservoir, is there a way to tell how much gas and how much water produced from outputs? Thanks Jing

compile using gfortran

I'm sorry to ask questions so many times, but I can count on only this forum. I read https://tough.forumbee.com/t/80xxf4/install-of-tough2 , and I'm facing the same (Ana Avila 's compiler) problem.…

Initial condition setting with MINC

HI All, If I activate MINC and set the porosity in the following way, will the porosity apply to both matrix and fracture element? I use this method to assign the porosity,…

Fracture porosity when using MINC in Tough2

Hi All, When we choose MINC in tough2, we need to input the porosity of fracture in the material data as in the following screen shot. What is the definition of the fracture porosity here?…

Suppress CO2 dissolution in TOUGH2

Hello all, I am trying to suppress CO2 dissolution in TOUGH2 (set CO2 solubility in brine as 0) to investigate how big the impact that CO2 dissolution can have on CO2 plume migration.…

Problem with RF1 input file

Hello everyone, I'm starting to use TOUGH2 for the first time. I tried to run the sample-input file RF1, but the output file gives me an error and I don't know how to proceed.…

MINC to simulate dual-porosity reservoir, with some fractures are open, some are closed.

I'm using MINC to simulate dual-porosity reservoir, since I assume some fractures are open, some are closed, could I assign different permeability or porosity to fracture elements based on…

MINC and GENER

Hi, dear all Thanks for the last answer to my question, and it's very useful for me. Well, when I use MINC model, GENER seems to be unavailable. (output file says "REFERENCE TO UNKNOWN ELEMENT…

Starting with TOUGH2v2

Hello everyone, I have TOUGH2 distributed by NEA. I recieved a DVD containing TOUGH2 source code, all of the EOS modules with '.F ' extension, and some input data for the sample problems.…

Time Problem TOUGH2 with EOS7R

Hello everyone, I’m a new TOUGH2 user. I am trying to simulate a diffusive transport of nuclides in porous media. The input works and I get good results.…

appropriate time step

Hi, dear all How can I choose suitable time step size? If the time step size is too large, and convergence cannot be achieved, automatic time step reduction will occur,…

question about TOUGH2 output

Hi, dear all I'm working on geothermal model by using TOUGH2 with PetraSim. Now I want to conduct with model calibration by using PEST. To do so, I must output temperature from TOUGH2 model,…

Save file

hello, I've loaded initial condition (from a proper save file) and when the model finished the save file was empty. and in the OUTPUT file it says that it's not exist.…

Tough2-Flac Coupler

Hi, I was wondering if Tough2-Flac couple module is available to public? if yes where can I download it? Thanks, Attila

EOS1 - REDUCE TIME STEP error

Hello, I am simulating the single-phase radial flow of water to a well during 13 days of pumping test. I am using EOS1 with MULTI (1,2,2.6). After running the code,…

Installing T2 and iT2

Hey everyone, My colleague and I recently purchased T2 and iT2 through our University, however we both kinda suck at installing programs etc ... can anyone help us?!…

Tough+Realgasbrine

Hi there, I'm planning to attend the short course of Tough+Realgasbrine in September, is it a new module going to be released? Do you have any idea when will it be available? Thanks.

Injecting Hot Upflow with MINC

I am running a natural state geothermal model and running into the following issue: With a single-porosity model, the upflow condition is hot water injected, about 290 C.…

How to assign a permeability for each grid cell?

Hi. I am trying to convert an Eclipse simulation model to TOUGH2. In the Eclipse model each grid cell has a (diagonal) permeability tensor, with a scalar for permx, permy, and permz.…
