  1. Hello to everyone ! I would like to model CO2 injection into high temperature and high pressure EGS reservoir. I know that by default, ECO2N has limitations on maximum allowed temperature throught simulation (103.04 deg. C). This is fixed in CO2TAB file. However, from what I've read this can be changed. Therefore, I would like to extend temperature range to approx. 200 deg. C. My questions are following: 1) How exactly does the structure of this file look like? I mean the full syntax. Knowing this, I think I would be able to create my own file. 2) What is the reference state (or which convention is used) for specific enthalpy calculation ? I can obtain very accurate results for the density and dynamic viscosity (using CoolProp), but I cannot reproduce values for specific enthalpy. 3) Even when I create my own CO2TAB file (with 2 values for temperature and pressure), Petrasim is creating it's own CO2TAB file (default range, 127x51 values for P and T, respectively) after starup of simulation. Do I need to use "clean" TOUGH2 to include "new" co2tab file? 4) Can anyone provide me co2tab3.f and rco2h files (+instruction for compiling) to create my own range for co2tab file ? Alternatively, can anyone create CO2TAB file with temperature up to 200 deg. C (pressure as default - 600 bar) and send it to my e-mail ([email protected])? Best regards, Maciej
  2. Hi guys, Does anyone know where to find flow velocities in the output files ? I set KDATA=2 (I pointed it in Petrasim Output Controls) but can't find them in the output files. I also wanted to print vector values (net or average FLOF)for selected cells, but the foft.csv file doesn't contain them. Thanks for attention, Maciej
  3. Flow budget

    Hi, Did anyone tried to make a flow budget in Petrasim/TOUGH2 ? I know I can do it by selecting boundary elements, make a prinout from them and calculate it manually in Excel, but maybe someone has another method or some experience doing it ? Thank you for reading, Maciej
  4. Dear All My question touches how density and specific heat is defined in PetraSim. When I put density and specific heat for high porous rocks like clays, shales and others, material properties shall be typed considering dry rock, or fluid-saturated as it usually occurs ? For a porous rock it is a great difference. Thanks for all replies.
