INCON format in the *203t ECO2n samples

In the samples for Tough3 ECO2n, there are several cases whose name ends in 203t where the INCON keyword looks strange to me. For each element, there are 6 lines for the values of the primary…

Specifying material types for stratified heterogeneous reservoir

Dears, I am trying to model CO2 injection in heterogeneous aquifer that is composed of 23 layers with different porosity, permeability, and capillary pressure data.…

Conductive heat flow in output files?

Hi all, Is it possible to print specifically the conductive heat flow between two blocks? I believe the "HEAT" column in the output file and the COFT files contains all heat components (conductive,…

Cross flow between stacked layers

Dears, Is there is a way in TOUGH3 to output mass flow rate between stacked layers (NOT grid cells) with time?

Technical question regarding mass conservation in TOUGH3

Dears, I am trying to model CO2 injection in brine saturated aquifer using a 1D radial model. CO2 is injected with a constant rate (10 kg/s). Rate distribution throughout the reservoir in my case is…

Need help for EOS8 test

Dear all, I am trying to set up a test model using EOS8. I have generated the input file INFILE, and the mesh file separately. The mesh information (ELEME and CONNE0 are listed in this file.…

Specifying an injection well with a constant volumetric rate

Dears, I wonder if it is possible to define an injection well with a constant bottom hole injection rate (volumetric rate NOT mass rate) in TOUGH3/ECO2N using the GENER data block.…

How to deactivate the mutual solubility of CO2 - Brine mixture in TOUGH3/ECO2N

Dears, I am trying to model CO2 injection in saline aquifer reservoir. I would like to know if there is an option in TOUGH3/ECO2 to deactivate the mutual solubility between CO2 and brine.…

Parallel execution of simulation using TOUGH3 in windows

Dears, I am trying to run a simulation case using TOUGH3/ECO2 in windows and the simulation run lasts for a long time (more than 24 hr for numerical model 1650*10 grid blocks).…

TOUGH3 on PC: CPU timing routine

I recently used Ubuntu terminal to install TOUGH3 on a Windows 10 Laptop. In order to compile, I had to change a call to the CPU timing routine. In the esd-toughlib source code, file parallel_stubs.…

Incomplete simulation run

Hi, I have a problem with the attached simulation INFILE. The simulation terminates before the specified simulation time (only 0.778 s out of 10 years).…

T2Well

Hi I am trying to model the temperature distribution in the wellbore during CO2 injection. In the TOUGH3 manual, I find that T2Well can evaluate pressure and temperature profile within the wellbore.…

example of annual variation in extraction

¿Hay un ejemplo de un modelo en un estado transitorio en el que la extracción varía cada año, con EOS1?

Improve the stability of the numerical results

Dears, While modeling CO2 injection in a saline aquifer reservoir using ECO2n, I find the following instability in bottom hole injection pressure results.…

Changing inner grid boundary condition with time

Dears, I have been trying to model CO2 injection in a saline aquifer reservoir where the injection rate and injection temperature are constant during the injection period.…

Specify the composition of the injected fluid

I am trying to model the injection of water-saturated CO2 into a saline aquifer. My question is how to specify the composition of injected CO2 (OR water mass fraction in the injected CO2).

How to output all primary and secondary variables using the OUTPU data block in TOUGH3?

I am trying to output all primary and secondary variables (including enthalpy) using the data block "OUTPU", however, TOUGH3 ignores the keywords as illustrated in the following message in the…

Problem with running a sample case using TOUGH3/ECO2N

I have started to use TOUGH3 recently for my research. I am trying to model the temperature perturbation during CO2 injection into saline aquifers using TOUGH3/ECO2N.…

Compiling TOUGH3 on Linux platform (Ubuntu): Failed to configure TOUGH TPLS

I tried to compile TOUGH3 eos7ca, but the following error message showed up. I changed PETSC_VERSION_PATCH 6 to PETSC_VERSION_PATCH 4 and deleted /esd-tough3/build and /esd-tough3/tough3-install…

Installing Tough3 on Windows by using Bash

Hello! I am trying to install T3 on my Windows10 by using bash but this error comes up (please see the attached image). Apparently it's because the file name: " blas2.1.…

Failure in linear equation soluation

Hello! I am having a simulation (with EOS2) containing CO2 and heat injection and well on deliverability, but I run to this error: "FAILURE IN LINEAR EQUATION SOLUTION" What could be the source of…

Trouble finding local connections

Could someone please tell me (1) what is the meaning of these messages ? (2) 1540753 & 4707353 in the above image are names or #ID of elements or connections?…
