  1. Curve Column Static Line?

    I can think of a couple of ways to do this. 1. Add another curve to your LDFX file and your DAT files that is placed directly above or below the chloride curve (you can adjust the order of the columns by right clicking and choosing "send to back"). You'll have to assign it the same horizontal scale as the chloride curve, and you should add constant values to the DAT file. 2. If you can eyeball where the 100 mg/kg line is on the Log Design, you can add a vertical line to the LDFX file. I hope this helps. If you have additional questions, please let us know or contact us a tech @ rockware.com. Best Regards, Alison
  2. Plane history plot

    Amy, Unfortunately, I can't think of an easier way to do this. You might try looking at the connection data (stored in the conn.csv file) to see if there is anything here that might help with your calculations. Best Regards, Alison
  3. Temperature distribution

    Luca, I'm not sure why you would get a temperature of 0 in the model like this. If you'd like to send me your SIM file, I would be happy to take a look at it. Best Regards, Alison Alison @ Rockware.com
  4. Thank you for taking a look at PetraSim v2015! You should be able to import the v1.2 SIM file into the v2 model by going to File / Import TOUGHREACT as V2 menu. If you are doing this and still getting the described results, it would be very helpful if you could send us the following: 1. Your original v1.2 SIM file 2. The new SIM file after you imported the v1.2 SIM file (and saved). We have not yet added support for Aqueous Kinetics in the interface. I'll make sure that this in our the programmers list of features to add to the program. Best Regards, Alison (Alison @ rockware.com)
  5. Thomas, Thank you for letting us know that you found a solution! Best Regards, Alison
  6. Well productivity index

    The program does not seem to adjust the PI value based on the dz or varying k values. It does output the HG value, which is a cell thickness value. I believe that when calculating the PI for multi-cell wells, the dz would be the entire length of the well. I don't know what you would do in a situation with multiple k values. I would suggest that you submit this to the LBNL TOUGH2 forum, as the authors are better qualified to answer this question. Thanks, Alison
  7. EOS7C initial conditions

    Here is the PDF attachment. eos7c discussion-3.pdf
  8. EOS7C initial conditions

    I wanted to post a PDF discussion of this topic on the forum for others to look at. The initial mass fraction of NCG is in the aqueous phase. The equation of state will calculate the equilibrium value in the gas phase. The remaining gas will be methane. Because a very small mass fraction of aqueous N2 leads to a much larger equilibrium mass fraction of gas, you have to use very low initial NCG values during initialization. Thanks to Dan Swenson at Thunderhead for putting this together. If anyone would like to see the spreasheet or SIM files used here, please contact me at alison @ rockware.com. Thanks, Alison
  9. Exporting Water Types from AqQA

    Unfortunately, AqQA does not include any tools for a mass export of the data analysis information. We will put this on the wishlist for a future version of the program. Best Regards, Alison
  10. EOS7C initial conditions

    Amy, I have also had a hard time initializing a model with very little methane and mostly NCG using EOS7C. If you would like to send me your SIM file, I can experiment a bit with that, but think that this might be a better question for the LBNL TOUGH2 forum. It is my understanding that you would want to make the NCG mass fraction very large. Whatever part of the gas phase that is not make up of water vapor or NCG will be methane. Best Regards, Alison
  11. flow mass fraction

    Could you tell me where the PetraSim program is producing a flow mass fraction? Are you referring to output in the well plot, or in sink/source plots? Best Regards, Alison
  12. I-data contouring based on depth?

    It is hard to know what the problem is without looking at your actual data. It sounds like you are doing everything correctly, although you should not have to "Create a New Model" each time you create a surface map. Instead, I would recommend that you use the same RWMOD file each, time and simply vary the RWGRD file you use. You might try viewing your RWMOD in 3D along with your surface to see what kind of concentrations intersect the surface. If you continue to have problems, feel free to send a backup of your database, along with your RWMOD and RWGRD files to tech @ rockware.com, and we would be happy to take a look. The create a backup of your database, go to File / Backup Database, and send use the zip file created during the backup process. Best Regards, Alison
  13. I-data contouring based on depth?

    If you have a ground surface grid, you should be able to use the Grid / Math / Grid and Constant Math tool to create grids at certain depths below ground surface. You can then use the I-Data / Surface Map option to create contours of chloride at specific depths below ground surface. If you take this approach, you wouldn't have to modify your existing project. Regards, Alison
  14. entalphy

    Question 1: TOUGH2 EOS1 uses two variables (X1, X2) to define the state. If it is single phase conditions, the two parameters are P and T. If it is two phase, then the parameters are Pg and Sg. If the X2 is >1.5, then it assumes it is a pressure. So the variables are handled as a pair and there is not a question of which is first or second. Question 2: Basically, during injection you are adding mass and energy to a cell. The cell will then determine its new state by mixing the existing fluid in the cell with the new fluid flowing into the cell. The user will have to estimate the pressure (or saturation) of injection and use that in calculating enthalpy. My guess is that usually injected fluid is single phase and then enthalpy is not a strong function of pressure. Best Regards, Alison
  15. I-data display issue in 2d Striplog (RW 16)

    The background grid lines are plotted based on the Total Depth value stored in the Location table in the database. Please check to see if the Total Depth field is incorrect (and too shallow) for this borehole. If you continue to have problems, feel free to send an example image to tech @ rockware.com Best Regards, Alison
  16. How to read the output file

    Assuming that you are using version 5.4 of PetraSim, the program uses an alphanumeric system for naming the elements in a model. The first 999 cells have values between 001 and 999, and then the program moves on the A00 and so on. When looking at an output file, you'll see that the simulator will often list the cell with the highest residual along with any errors. If you want to identify that cell in the model, you can type the cell name into the Find window in the upper right hand corner of the program and then click on the enter button. That cell will be graphically highlighted in the display. I hope this helps. Please let us know if you have any additional questions. Best Regards, Alison (Alison @ rockware.com)
  17. Model drawdown surface

    1. You could certainly give it a try. Just keep in mind that the interpolation algorithms in RockWorks may not create a really pretty cone around the extraction well, unless you have a good distribution of observation points around the well. This could be done by creating a list of xyz elevations in the Utilities Datasheet, and create a contour map through the Map /Grid-Based map menu. 2. I would suggest that you take a look at the Drawdown_Simplified_01.rwdat file to see how you should arrange the data. You can find menu settings specific to this data file in the Drawdown_Simplified_01.rcl file. To load these menu settings, go to Drawdown Surface/Simplified and then click on the hammer button in the upper left hand corner to load the RCL file.
  18. Model drawdown surface

    Anna, Unfortunately, RockWorks really isn't designed to work with this type of data. The drawdown tools in the Utilities calculate drawdown based on pumping rate, well radius and other parameters using the Theis equation. What exactly are you hoping to do with this data? Would you like to approximate aquifer properties based on the results of the step tests? If you could provide additional details, I can let you know if we carry other programs that would meet your needs (Aqtesolv, AquiferWin32, etc.). Best Regards, Alison
  19. Using EQuIS data in Rockworks 16?

    Unless you are using an older version of EQUIS, you should have an option to create a RockWorks15 database. I believe that you have to have RockWorks15 installed to do this. If you would like to install a temporary version of RockWorks15 so that you can use this export option, feel free to contact us at tech @ rockware.com. A RockWorks15 database can be easily imported in RockWorks16, so this might be the most efficient way of data transfer until RockWorks16 is supported by EarthSoft.
  20. Jaeshik, Its hard to envision what you are seeing here or what might be the problem. Please send me your SIM file, and I will take a look to determine if this is a problem with PetraSim. Thanks, Alison alison @ rockware.com
  21. It turns out that recalculating the XYZ values through the Edit menu solved this problem for Andy. We're not quite sure why they were not calculated in the first place, so if anyone else runs into this problem, it would be helpful if you could let us know by sending a quick email to tech @ rockware.com. Thanks, Alison
  22. Andy, I'd be happy to look into this. Could you tell me what type of data you are exporting (I-Data, T-Data, etc.)? Also, what revision of RockWorks are you using? This should be listed in the lower right hand corner of the program. Thanks, Alison
  23. I would suggest that you export the Shapefile through the File / Export menu, rather than through RockPlot3D. This will create a shapefile that contains actual contamination values. You can find a case study on the RockWorks support page that covers the shapefile export options in RockWorks. If you need a direct link to this (unfortunately, I can't post it on the forum), please contact me at Alison @ rockware.com.
  24. Display elevation in striplog?

    There is an option to display elevations along with depths in a 2D striplog. This “Include Elevations” option is enabled through the Depth Bar Options in the 2D Striplog Designer. You could also add a second scalebar to a 2D striplog through the Draw / Insert menu in RockPlot2D, but this would have to be added individually for each striplog. Please let us know if you have additional questions. Thanks, Alison
  25. Import a Rw3D file into datasheet Utilities

    Loann, You will need to list the names of the RW3D file in column 1 of an RWDAT file (so if you have three RW3D files, you should have three files listed in rows 1 through 3 of Column 1). You'll also need to be sure that the RW3D files are located in your current project folder. If you would like to manually select the files by double clicking on the cells in the RWDAT file, you should change the column type to a File Name. To do this, go to Column / Column Properties, and select "File Name" under Linked Data. If you continue to have problems, please send your RWDAT file and RW3D files to tech @ Rockware.com. Thanks, Alison
