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,…

Link to Training Material is not working

The link to training material on TOUGH Short Courses website is not working, it would be really helpful if someone could fix this. Thanks!

Set An Initial Temperature Greater Than 100 In ECO2N Module

Dear all members, Hi, I am a new TOUGH user and I know that by default, ECO2N has limitations on maximum allowed temperature (103.04 deg. C). But in my case the temperature is 120 deg.…

How to apply this unique Mix of Neuman + Dirichlet Boundary conditions, for Temperature & Pressure, 1-d Problem

Hello everyone I am trying to setup a 1-D validation problem from a research paper for validating experimental results. In short, I need to apply Neuman & Dirichlet Boundary conditions,…

Hysteretic RELP and CAP

Hi, Just a quick question: Is it possible to use IPR 12 with ICP 9 ? Following the manual, it should only be implemented with ICP 12, since ICP 12 uses some parameters from IPR 12,…

Partitioning Tracer-EOS7C

Hi, I have two question 1- Regarding temperature dependency of Henry's coefficient, I was wondering if TOUGH2/EOS7C considers this or not? and if yes, at what reference temperature should HCTRC…

CONNECTION in Mesh file

Hi, dear all, I am recently having problems in defining the connected elements in the MESH file. I opened the MESH file, and I found there is error in "CONNE" part (own code in writing the MESH…

EOS7 - Specifying initial conditions

Hi all, I want to specify this initial condition using EOS7: Reservoir temperature: 240 degC Chloride concentration: 600 ppm weight = 0.06%-wt CO2 concentration: 0.5%-wt Steam fraction: 0.…

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…

Wettability and capillary pressure direction in TOUGH2

Previous discussions indicate that the direction for Pc is always "pulling" the wetting component toward lower saturation regions. Does TOUGH assume the aqueous phase is always the wetting phase ?…

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.…

WellModel - ftype

Hi everyone, has anyone coupled the Wellsim wellbore simulator to tough2? as a f-type generator for example?

Is pore compressibility in TOUGH2 not identical to bulk compressibility(1/K)?

Hello. Recently, I am trying to solve 1-D consolidation problem(Terzaghi's) with TOUGH-FLAC. In order to solve it, I first run FLAC to consider pore pressure generation(Skempton's effect).…

Five-spot Geothermal production/injection

Hei guyz. I'm new learning how to use tough2 and working with CO2 injection using EOS2. My project should be of type 9.4 problem No. 4. Therefore, i have been studying this problem.…

A problem about Capillary pressure!

Hello everyone! I make only one cell to simulate the capillary pressure in EOS3, and I use linear function (ICP=1).Sl=0,Pcap=1000Pa; Sl=1,Pcap=0. I set the gas saturation as 0.…

Pressure-dependent Neumann Boundary condition

Dear all, Dose anyone know how to set up a pressure-dependent Neumann Boundary condition in TOUGH2? Like evaporation problem, how can I set up the evaporation amount (in GENER block) as a function…

Problem initializing water table at a given elevation in eos9

Hello, In the TOUGH2 manual, it says that an eos9 (Richard's Equation) model can be initialized with a specified water table elevation by setting CWET in REFCO to that elevation.…

How to switch between injection well to production well (time dependent)

Hi, Everyone, I am a PhD student. I need some urgent help in the TOUGH2. I wan to switch the well properties between the injection well and the production well during the simulation.…

Recharge via time-dependent Neumann & deliverability boundaries in EOS9

Hello, I am trying to model recharge to a shallow aquifer using a 20 m-deep 1-D (1 m x 1m cross-section) iTOUGH2-EOS9 model in which I incorporate the following processes:…
