TEMPERATURE = 0.000000E+00 OUT OF RANGE IN SAT

Hi All, I am a newbie to the TOUGH simulator and trying to create a small model for brine injection using EOS7 module. While I am trying to run the model,…

Radial mesh

Hi all, I am using radial mesh to model a column, which is defined by R and Z. Is it possible to model only 1/4 of the column with a theta (θ)? I don't see where to set this. Regards, Antonio

Why does the partial pressure of carbon dioxide change so much when SG is greater than zero？

I use eos2 to simulate phase transition (phase change) it is a very simple model to study the Pco2 change. but it is a little bit hard to explain. I found SG>0,…

Steady-state simulation of a low-type geothermal system

Dear TOUGH2 Users Good morning/afternoon This is my first post to this forum and I’d like to receive guidance and help to perform a steady-state natural simulation model of a low-type geothermal…

Liquid saturation definition

Recently, I showed my simulation results to my colleagues. I was asked a question, what is the liquid saturation and gas saturation. I have tried to explain, but I was confused finally.…

Can we used a Neumann boundary condition for temperature simulation in TOUGH2?

If I know the heat flux (18 W/m^2), should I use the Neumann boundary condition? can I use it in TOUGH2? Thanks

methane leak and plume migration in subsurface from hydrocarbon wellbores

Hi There, I would like to know what module would be best to simulate methane leakage and plume migration in the subsurface from hydrocarbon wellbores? I did some digging and came across some…

MINC processing for fractured media

TOUGH2; grids; running time too long

Hi! I used TOUGH2 for a transient fluid flow analysis (total time for 1 year) using grids showed in the figure. Element volumes range from 1.0e-04 to 2.0e-1.…

In-situ Combustion for Oil and Gas

Hi everyone, My company is considering to get a TOUGH license and wondering if it is suitable for our project. I am wondering if we can use it for in-situ combustion for oil and gas extraction.…

representing an oven using extra cell

Hi everyone, I’m trying to use TOUGH2 to history match a column test where some soil was put inside a glass column and sealed and then put the column itself inside an oven set at some elevated…

Issue with using EXT for extracting data from TOUGH2 MESH and OUTPUT files

I have compiled and linked the EXT fortran source codes downloaded at: https://tough.lbl.gov/licensing-download/free-software-download/. I received the following error messages when using the…

How to conduct a both saturated and unsaturated analysis in a computational domain?

Hi! Recently, I have been focusing on simulating the evaporation of moisture at a cavity surface to see the desaturated process near the cavity surface using TOUTGH2(EOS3).…

How to print K(LIQ) and K(GAS)

Hi everyone, I am using TOUGH2- ECO2N, and I would like to print the gas and liquid phase relative permeabilities. I checked in the manual, but I did not find the answer.…

Atmospheric boundary condition with evaporation

Hi all, Recently I'm trying to build an simple model for rainfall filtration in vadose zone with TOUGH2 EOS3. I have read Anthony and Stefan's discussions on this topic four years ago,…

Temperatures above initial condition temp using injection and production scenario with EOS1

Hello, I am modelling the flow of water through heterogeneous media by using two wells, an injector and producer over a 25 year period. The initial temperature condition is set to 100 degrees C and…
