Hello to everyone ! ***I apologize for copying the post, but I have published the previous one in the wrong section.*** I would like to model CO2 injection into high temperature and high pressure…

Beginner

Hello everyone, I just got Petrasim+Tough2 licence from work but I have no idea where to start and how to start. I have noone around to ask and no experience with other simulators either.…

Fortran runtime error!!

Hi, I am running a model with EOS7C on UNIX. The code seems working with no convergence error. But, I always get: Fortran runtime error: Expected REAL for item 14 in formatted transfer,…

Actually, I need a software I could model the Coupling Thermo-Hydro-Mechanical damage.

I was wondering if this software(TOUGH2) is suit for this purpose or not. please let me know if you have any more information in this area.Thanks

mesh creation

I have a question regarding mesh creation. I am working with Petrasim, T2VOC. I appreciate if you could help me. Is there any limitation for creating mesh?…

What if the model does't have boundary setting?

Hallow everyone! I'm a beginner of TOUGH. All the time, i always use the dirichlet boundary by giving a 1E50 volume. Today, an idea come to me : What if the model does't have any boundary settings?…

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…

How to define heterogeneity in TOUGH2-ECO2N

Hi I am a new TOUGH user. I am interested in learning about defining fluid injection models with TOUGH2. I would like to learn about building heterogeneous models - which Kx and Ky differ from one…

Modeling of flow of bitumen in porous media

Dear all, I want to model the shaft seal of repository in clay. The shaft seal consists of bentonite plugs and gravel column filled with bitumen. The goal of modeling is to investigate the behavior…

Initial/boundary conditions for discharge from spring (ECO2N)

Hello, I am trying to use ECO2N to model a system where salty, CO2-rich water is upwelling into a shallow freshwater aquifer that is horizontal for some distance,…

anisotropic permeability for TOUGH3-EOS7

Dear all, I am trying to modify my INFILE (isotropic permeability) to specify anisotropic permeability element-by-element. My original INFILE (isotropic permeability cases,…

Increasing the number of rock materials

Hi everyone, I am working with TOUGH2/EOS7C. I need to use 44 different rock materials in the ROCKS. I am wondering if there is any way that I can increase the number of rock materials from 27 to 44…

How to simulate a tide boundary?

Hello, everyone, I am a new TOUGH2 user. I want to creat a model using EOS3 module. The left boundary of the model is a water-land interface. The mean sea level is assumed to be 6m below the ground…

System of equations for EOS4

Hello, I am trying to write the system of equations for EOS4. But one equation is missing. I think it is the relation between mass fraction of water in gas phase (or mass fraction of air in gas…

Quick fix of a bug in ECO2N V2.0

In the ECO2N V2.0 User’s Guide, it says that setting IE(16)=1 invokes the CO2/brine mutual solubility formulation from ECO2N V1.0 for low temperature (<99C).…

modelling a river

Hi, What is the best way to define a b.c. for a river (standing water body)? I have leak point at some depth below the bottom of a river within a groundwater.…

ECO2N, Model initial temperature distribution

Dear all members, Hi, I'm working on thermal injection simulation in TOUGH2 and I want to define an initial temperature distribution for my model. After program execution (ECO2N),…

Effective or Total Porosity in TOUGH2 EOS1

Migrated from Rockware Support Forum: Does TOUGH2 EOS1 assume total porosity or effective porosity for water? Is there a built-in conversion from one to the other?

Big alternating in/out fluxes along sloped water table boundary

Hello, I am using iTOUGH2-ECO2N to investigate upwelling of CO2-laden brine into a shallow aquifer system, but I am having a problem with the initialization of the flow model and would appreciate…

Error in defining Heterogeneous Regions with Meshmaker 1.5

Hi everybody, I have a question about geometry definition in meshmaker. I tried to define a very simple layered material by using meshmaker 1.5, and I tried to define the layers by heterogeneous…

ECO2N permeability modification

Hi all, I have a question about random permeability modification using ECO2N. When I include a SEED dummy domain in ROCKS and use input parameters for logarithmic permeability modification,…

Hello，everyone！ I have some question about compile TOUGH2 code. I have two fortran compiler,but I can only compile TOUGH2 code follow the suggest giving in https://tough.forumbee.…

The relationship between S_l and P_cap is not consistent with the van Genuchten function

Hi, I am using ECO2N for simulating CO2 storage. I wanted to verify that the relationship between the liquid saturation, S_l, and the capillary pressure, P_cap,…

Maximum MCYC

Hi. Although I set MCYC (maximum number of time steps) to more than 1000, TOUGH2 calculation stops at KCYC=1000. Is maximum value of MCYC 1000 ? (This is not described in TOUGH2 manual...…
