EOS7C poor convergence, e.g., in subroutine SOLIT

EOS7C v.1 models five components (water, brine, CO2 or N2, tracer, and CH4) and heat. Many users have noticed that time-step convergence can become poor during CO2 injection problems,…

Defining a multi-layered aquifer in TOUGH2

Dear All, I am trying to simulate a sandstone aquifer capped by two sealing layers (Shale and evaporite), so there are totally 3 layers in my model. I think there are two blocks in the input file…

CO2 storage in saline aquifer with ECO2N

Hello All, I am working on CO2 storage using ECO2N. In the output file, we have the following variables. "P T SG SS XNACL YH2OG XCO2aq PCAP k-red" How can I calculate the Mobile CO2,…

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.…

Time stepping in dry-out zones

Hello all, I know it is a general question, but any hint will be appreciated. I am running a 3D model of CO2 injection into a layered aquifer using the ECO2N module.…

Question on the block of CONNE

Hello everyone, I have a question on the block of CONNE. Whether can I only input part of the connections between two cells instead of all the connections?…

Integrated CO2 injection modeling for studying flow distribution aspects in well (&well formation?) in CO2 injection wells in Tough2-ECO2M

Dear All, I am doing my Master's Thesis about CO2 modeling with phase changes (critical, liquid and gaseous form). Could you tell me please, is it possible to make such modeling in Tough2? - if so,…

TOUGHREACT1.2/ECO2N: About the inject rate and maximum pressure

Hi, everyone I'm using TOUGHREACT1.2/ECO2N with Petrasim. I am simulating the injection of CO2(isothermal) at a constant rate of 6.5kg/s（just one GENER）using a rectangle mesh,…

Converting single porosity mesh into dual porosity (dual-perm) mesh

By any chance, does anyone know a way of converting single porosity mesh elements file into dual porosity (dual-perm) mesh model file (with correct connections)? Would appreciate any feedback.…

Simulated CO2 injection into aquifers using T2WELL/ECO2M did not run successfully

Dear TOUGH community users, I am new to T2WELL/ECO2M and I am simulating CO2 injection into the aquifer, establishing a model of 0~-900m, the aquifer is located at -750~-800m,…

How to Use Toughio to Convert TOUGH2 Simulation Data to CSV Format and Resolve an Error？

大家好， 我下载了 Toughio，目的是将使用 Petrasim 生成的网格数据中的 TOUGH2 仿真结果转换为 CSV 格式，以便进行可视化和分析。但是，我对Python语言完全不熟悉，并且遇到了一些困难。 我知道 Toughio 提供了用于数据导出的“导出”或“提取”等程序，但我不确定确切的步骤以及如何输入命令。我尝试使用一些示例命令运行“提取”程序，但遇到以下错误：…

ECO2M:run is not convergent

Dear TOUGH community users, I am using T2WELL/ECO2M to simulate the injection of CO2 into the aquifer, building a model of 0~-900 m (3D) and the aquifer is located in-750m~-800m.…

The Example in TOUGH2's ECO2N：Radial Flow from a CO2 Injection Well

Dear all, I am using TOUGH2 ECO2N and I have confused about the example in Page 28 of the manual ECO2N: A TOUGH2 Fluid Property Module for Mixtures of Water,…

How to import field reservoir properties data into reservoir model in TOUGH2?

Hi everyone, I have field data showing spatial temperature and salinity variation of a given reservoir. I would like to know if these data can be imported in a reservoir model in TOUGH2.…

Relative permeability curves in tough2

Hello Every one I faced problem with the relative permeability curve while I working with tough2.1 to build a 3D reservor model for CO2 storage by using both the source code and also the petrasim…

Residual and solubility trapping

Hello everyone. I am working on Co2 storage using both ECO2N answer ECO2M. In the result we have 1-sg which represents the saturation of CO2 in gas phase.…

T2Well questions

Hi there, Starting to play around with T2Well and having good fun. ;) Two things (at least) that I didn't understood: 1- ROCKS data block: the domain name for wellbore cells starting with 'x'.…

T2Well constant fluid properties and EOS1 relationship?

Hi, I am currently modelling a wellbore with constant density, thermal conductivity and specific heat capacity thermophysical properties at surface temperature 40 degrees like so: Wella 2 1665.e00 1.…

Temperature limits of various ECO2N versions

Hi Folks, Anybody can send me a few words on this: We have a version of ECO2N (as a part of iTough2.7.0.) which doesn't perform with T>103.4, same indication seen in CO2Tab data that is limited to…

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…

Questions on NAPL volatile and dissolution

Hello everyone and Stefan, I have several questions on NAPL volatile and dissolution into water. Based on the manual, volatile is controlled by temperature,…

libgcc-s-dw2-1.dll & libgfortran-3.dll

I want to run executable file for Tough2 EOS7CA. I receive the following error messages: "The code execution cannot proceed because libgcc-s-dw2-1.dll was not found.…

TOUGH-FLAC coupling

Hi, I am trying to use a coupled TOUGH-FLAC simulation on a reservoir model. I am just starting with a simple 'cube' model with uniform properties. I went through some of the works done by Jonny…

How to inject CO2 using eos2

Hi. I want to inject CO2 of 1000 ton/day and H2O of 2400 ton/day into model domain (1.5* 10 km) using EOS2. Following advice in https://tough.forumbee.…
