Getting Started: Homogenous Aquifer

Hi, 

I am getting started with TOUGH3 and have not run a simulation. This is my first time attempting any substantial numerical modeling. I would like to create an infile to run 30 years with a homogenous reservoir for one production well, one injection well, no lateral boundaries, massflow and temperature of producer/injection changing over time, either confined or unconfined aquifer. I assume that I have to run EOS3. Since this is a very simple problem, where can I find an example of how to build the infile without 40 pages of equations interspersed?

Thank you!

    TOUGH comes with samples in the "sample" folder.

    You may try toughio-dash [1] to edit the INPUT-Files.

    And the articles on this page [2] helped me a lot.

      Jan Tecklenburg I do like the tips and tricks. There are not as many specific examples for what I had envisioned, but there are useful tidbits. The TOUGHIO-Dash is something I am hopeful for. The documentation really is not there yet, however, and the initial boundary conditions for the GUI are unlabeled boxes. I am not sure how to engage that unless someone holds my hand through it. (I know, the shame)

      Hi Nicholas Fry ,

      If you are not afraid of Python, I would recommend using the Python package toughio to set up your problem. There are a couple of examples in the documentation, for instance, this one (https://keurfonluu.github.io/toughio/examples/co2_leakage_along_a_fault/index.html) will show you how to set up a TOUGH simulation and visualize the results.

      Apologies for the lack of documentation, I am totally aware of this issue and should definitely be working on improving it.

      Keurfon Luu I am less afraid of Python than I am of TOUGH, so I will check out the suggestion. Thank you.

    Hi everyone,

    I think I have a relatively simple question. On what page of the manual are the definitions for the column names per keyword? -- place that I can find what goes in a column and the units in which TOUGH reads that column. For example -- What does ROCKS, column 7 mean (TC), and what units are TC in? I am ctrl-f'ing my way around without any luck.
    Thanks for your time.

    TOUGH always uses SI units. TC at here is the formation heat conductivity under fully liquid-saturated conditions and has a unit of  W/m˚C.

      My question is, where is the text stating what properties go in which column of the INFILE? Is there another name for "column" that the user guide references? I do not see this information.
      The words "thermal conductivity" appear on page 12, 17, and 18. None of these locations state where the thermal conductivity values go inside of the INFILE columns. Someone else told me where to put them in the file. I would like to know how to find the information myself.

    See the corresponding keywords in user manual section 8, such "ROCKS' section for information of Rocks.

    I see. So, the columns are not numbered in the user guide, but they are in the INFILE. What does Format(A5, I5, 7E10.4) mean in the first line of the manual after keyword ROCKS?
