All Activity

A new version of RockWorks was uploaded to the RockWare website, with new features, improvements, and bug fixes. The RockWorks Revision History includes complete lists, by date, of all changes in the program. New Features: A button titled "Set to Project's Values" has been added to the Borehole Operations / Lithology / Volumetrics menu. This button will copy the values for the current Project Dimensions to the Upper Elevation, Lower Elevation, and Interval. A button has been added to adjust the end point coordinates to match the value range. It is now possible to automatically set the elevation for the image within the Graphics / Images / Float program to the project minimum or maximum z-value. These new options are also available within the 3D program that include an option for adding a floating image to the diagram. The Cage options which are used to add perimeter annotation to 3D diagrams now include an option to add a small north arrow to the diagram. A smoothing option has been added to the ModOps / Solid / Extract Grids / Solid → Thickness Grid. Several new options have been added to the Multivariate Lithology Map menu that is accessed via the Borehole Operations / Lithology pull-down menu. The Dimensions / Scan programs now include an option to add a buffer around the suggested project dimensions. The DEM (Digital Elevation Model) import program now includes options for specifying if the elevation data is stored in a South-to-North or West-to-East fashion. Grids surface displayed in RockPlot3D can now include contours. Contour lines may now be added to 3D surface diagrams directly. Titles may now be added to 3D diagrams directly. A new option has been added to the 3D Log Designer / Lithologic Interval Labeling that can be used to limit the labeling to lithologies with specific g-values. Improvements: It is now possible to adjust the opacity of the background image within two-dimensional maps. A "Select Properties" has been added to the RockPlot2D popup menu. It allows users to select from a number of items when there is more than one item under the cursor. Upon completion, the Playlist now scrolls to the first checked item within the list. This makes it easier to test items within long playlists. When you select several Playlist items, you can enable/disable them all at once. The selected items can also be edited as text vs. editing the entire Playlist. The T-Data Time Graph program now has the option to specify the Date/Time format. The vertical height of the tabs within multi-page menus has been decreased from 40 to 30 pixels to minimize the amount of scrolling that is necessary when viewing menus within the Playlist. The ASCII DEM -> Grid program runs a bit faster when extracting portions of a DEM to a grid based on the Project Dimensions. Bug Fixes: The Borehole Map no longer displays at maximum extent if no labels are plotted. Editing selected playlist items will now copy the items back to the same locations without jumping around. Borehole Manager - File | Export | P-Data, I-Data & T-Data | All Tracks, can be set to measure Depths from the Collar Elevation without an error. Programs within the Playlist that are unable to create 3D logs due to no data will no longer interrupt the processing with warning messages. Instead, the warning message will be added to the Execution History listing. The Lithology Label Intervals / Center Text option within the 3D Log Designer now only posts labels on the logs.

Many thanks for your fast feedback and quick change!

Thomas, I just wanted to let you know that we have added a new feature to PetraSim v2024 based on you suggestions. We hope to release this later this month, but feel free to contact me if you would like to try out a beta version. The program will now allow the user to select the upper-most or lower-most exposed elements in a model. Best Regards, Alison

Hi Alison, Thank You

For some reason, I'm not able to add an image. so here is the text that you can copy and paste into the OUTPU block: OUTPU----1----*----2----*----3----*----4----*----5----*----6 PETRASIM 4 SET 1 SET 2 ABSOLUTE 0 RELATIVE 0

Prince, I am not sure that TOUGH3 is designed to output either of these parameters. I am about to output Absolute Permeability (which take into account the PMX value) and Relative Permeability using the OUTPU block displayed in the attached image. I would suggest that you contact LBL to see if its possible to output these other two parameters. Best Regards, Alison

Hello, I am working on TOUGH3 (ECO2N) using PetraSim to solve the injection of CO2 in Heterogeneous model, and I want to print k-red (permeability reduction) and PER_MOD (permeability modifier) in output file. Earlier, I used TOUGH2 using PetraSim, which able to print both parameters (k-red & PER_MOD) on its default setting. Now I am shifting to TOUGH3 using PetraSim. I enabled the OUTPU tab and Its on default settings. But its not printing k-red & PER_MOD. I tried some modifications as suggested on internet by some users. But I am not getting correct solution. Thanking You

Hi Norihiro, Could you please send me your SIM File? I am not sure what this is, but think I can help after taking a look at the file and determining what simulator and output settings you are using. Best Regards, Alison alison@rockware.com

Hi, I see "X per m^2", "Y per m^2", and "Z per m^2" are in a list of vector values in 3D Result view in PetraSim. I tried but failed to find explanation for these values in PetraSim and TOUGH manuals. It would be helpful if anyone can explain me or give me a hint to find out their meaning. Thank you in advance, Norihiro

That is what I was looking for, thank you!

Thanks for the update on this. It unfortunately seems that you may need to select these manually. If it would be appropriate for them to all be assigned the same material type, then this is a cell parameter that is selectable (right click on the material and choose "Select Visible Cells". Also, as you've found, if you assign a name to selected cells, they are listed under Named/Print cells. These are not "groupable", but you can selected multiple cells at once by holding down the Shift or Ctrl keys. I will pass your suggestions over to our programming team.

Dear Alison, Thank you for your response. I attempted to follow your instructions, but unfortunately, it did not yield the desired outcome. Several cells remain selected on the top of the internal boundary, and not just the upper one. Additionally, I considered utilizing the Statistics feature to input a list of elements (copy paste) associated with known IDs (since I can easily access the list of active elements, and thus only the upper ones). However, it appears that the Statistics function only allows for the input of one element at a time, which is rather inconvenient. I would greatly appreciate any solutions for future releases to enhance the flexibility of element selection. Select upper active element of an internal boundary Group to store Named cells Statistics with several input at once (copy paste a list) Best regards

I think that you also might be trying to find these fields in the Borehole Manager, as they are hidden by default. In the Stratigraphy table, you can click the "Tab Manager" button to expose these. With the Stratigraphy table highlighted, click "Edit Fields". You can then check on the Dip and Dip Direction fields for the Top and Base contacts.

If you continue to run in to issues please feel free to send us your data at tech@rockware.com and we would be happy to take a look at it as well.

Good morning, When running the tool ModOps | Grid | Create | XYZ & Dips -> Grid please ensure that under the Data Columns tab you have selected each column. If one of those values is not selected correctly it could cause the error message you have mentioned. Another item to check on would be to confirm that your Grid & Block Model Dimensions are updated to match the data within the RockWorks datasheet. If they are not you can set up the Dimensions but selecting the Dimensions tab | Scan | Datasheet -> Dimensions.

I want to use the Dip interpolation as in this video, but I do not find where to input the strike and dip data in the borehole manager. Also when trying to make a dip interpolation from the datasheet, I get the "This program requires at least 1 data points" error, despite having multiple points. How exactly should I use the Dip interpolation?

An updated version of LogPlot has been loaded to the RockWare website! Bug Fix: The Fillbar data can now be loaded without issues which became apparent once we added the Munsell Colors to Lithology data. You can refer to the complete LogPlot revision list: https://www.rockware.com/support/logplot-support/logplot-revision-list/ To download this build visit the LogPlot Free Trial tab (https://www.rockware.com/product/logplot/) where you can download the installation program and install the new build. Note that the software will not be automatically licensed if your maintenance has expired before March 2024, and the software will be installed in trial mode. If you would like to renew your maintenance, contact RockWare Sales. Katy Duncan RockWare Inc

A new version of RockWorks was uploaded to the RockWare website, with new features, improvements, and bug fixes. The RockWorks Revision History includes complete lists, by date, of all changes in the program. New Features: A new DEM importer has been added to the ModOps / Grid / Import menu. This program handles "generic" DEMs versus the "Legacy" importers that are hardwired to antiquated (pre-2008) USGS and Canadian formats. A new program titled “Soundings → Boolean Solid” has been added to the ModOps / Solid / Create pull-down menu. The RockPlot2D Circle item can now be drawn as a Circle, Square, Triangle, Diamond or Star. It has been renamed to "Shape". The Bubble map option in the Point Map program can now plot points as Circle, Square, Tringles, Diamonds or Stars. This feature has been renamed "Proportional Shapes". The Playlist shows comments in yellow without a check box. Improvements: Documentation added to ModOps / Grid / Import / GeoTiff menu. The RockWorks GeoTiff importer allows the user to select between one and four GeoTiff files. The ModOps / Volume / Extract Via Surface Excavation program no longer extends the pit outside of the lease boundary if the Add Benches option is enabled. The lithology and stratigraphy volumetric reports no longer include the "Undefined" volumetrics within the "Total" column calculations. The Plot Polygon from the Polygon Table dialog now offers an option to fill the polygon. A 'G Filter' has been added to the Borehole Map Proportional Shapes program. ReportWorks now updates the caption filename after selecting a 'Save As' command on an unmodified file. Bug Fixes: The Borehole Map no longer displays at maximum extent if no labels are plotted. Borehole Manager | File | Import | Excel | Row Based has been fixed. When importing Location data into an empty project, the import would complain about duplicate boreholes even though there were no duplicates and the information imported correctly. Users can reset the graphical items defaults in RockPlot2D. Key strokes (arrows) are now being recognized when using the Playlist and its Ingredient menus. The RockPlot2D Scalebar has an added option to adjust the ending value if the Scalebar is resized, as well as other improvements. The RockPlot3D Color Legend is plotting small values correctly when the order is set to descending. RockPlot2D colorfill contour bands now use the min/mid/max color scheme and adjust the minimum interval (if the interval count is odd) to avoid problems with the bands not matching the contour lines. If a required field (like Depth to Base in Lithology or a LithoType) is missing, the program will report it, but you can then hide successive warnings. This allows large imports to proceed without hitting 'Enter' to dismiss each warning. To download this build, use the Help | Updates | Check for Updates menu inside RockWorks.

Thomas, This is a tricky problem because of the variable thickness of the elements in the Z direction. My only suggestion would be to right click on the internal boundary and click "Select Visible Cells". If this does not work with the current internal boundary, you might try creating one that is just below it to see if that works. If you continue to have problems, feel free to send us your SIM file and the TXT file used to create the internal boundary (to tech@rockware.com) and we'll experiment on our end. Best Regards, Alison

Dear all, I am currently utilizing Petrasim 2022.1003. For some reasons, I am employing an internal boundary to delineate the topography of the model, and so far, it has been effective. I utilized the internal boundary with an xyz file "DEM_tough_export.txt" to deactivate several upper elements (region 03), leaving the active domain as region 01. I am seeking an efficient method to solely select the upper active elements of region 01, which represent the topography. This is essential as I intend to set boundary conditions specifically for these elements. My initial approach was to create another internal boundary using a DEM offset of -5 meters. However, due to variations in element Dz, this method proved ineffective. Could you suggest an alternative solution to address this issue? I attach the picture below Thank you very much for your help, Best regards, Thomas

Further, is there a simple way to (iteratively...) "jackknife" the residuals by omitted a subset of boreholes and comparing the computed grid to the omitted elevations?

Hello, I have ~290 boreholes with stratigraphic picks; 5 units. Some boreholes only have 1 unit; some have all 5 units. I've variously created solid strat models and top/bottom unit grids for selected units. What is the best way to compute residuals for the top/bottom stratigraphic elevations, from the boreholes relative to the computed model/grids? Ideally, I would have them in both tabular form (to review statistical distribution) and mapped to see spatial distribution. I can do this in Arc/Python, but I would prefer to reduce the switching between software when possible. Thanks!

Hello, I have ~290 boreholes with stratigraphic picks; 5 strat units. Model area is 18,400 x 19,000 x 2,190 ft (XYZ, respectively); spacing is 500 x 500 x 10 ft. This is a reduced model size for quicker testing of variables and input data and will be expanded with a finer resolution once I've resolved the best approach. I also have a constraining surface of the DEM (same DEM that was used to compute the borehole elevations) and have a baseplate set to the lowermost unit. I have a surficial geologic map that I've converted into a raster/grid matching the project dimensions. For each surficial model cell without a "real" borehole and stratigraphic data, I've created a pseudo-borehole to represent the surficial geologic map. I set the borehole's location to the cell's centroid and set a stratigraphic interval of 0-10 ft to match the surficial map. The pseudo-boreholes are identified by a boolean field in the Location tab. [I alternately used (1) an interval of 0-unknown ft and (2) two intervals: 0-10 ft and 10-unknown. The three options don't seem to differ much in their results.] Conceptually, the inclusion of these pseudo-boreholes should result in a solid model (or layered model) that has a surface matching the surficial geologic map. Yet, I can't achieve the desired result. I've been tinkering with the modeling algorithm, modeling sequence, and other options, to no avail. Some are clearly more suitable than others, but none seem to generate a surface that truly matches expectations, even when hiding thin units in a layered model. The subsurface of my attempts still leaves something to be desired as well, but I have ideas for how to resolve that. What do you think the best approach would be for enforcing the surficial stratigraphy? I have to imagine that the inclusion of these data should be able to improve model results, but I'm struggling with the mechanism. In anticipation of the request to send the data for further investigation, I've also emailed the dataset (and this prompt) to the RW team. Thanks!

Just a quick update, the tech support solved our problem. Thank you, Vale

Thank you Alison, I'm going to contact the tech support. Best regards Vale
