  1. Importing excel

    Hi Archana, I cannot duplicate the problem with our files. You are welcome to send your files and a description of the procedure that you perform to [email protected], and I will follow your description to reproduce the problem. Include the LDFX, DAT, and Excel files. Regards, Tom B RockWare Inc
  2. LNAPL and Aquifer surfaces

    Hi Kahn, It looks like you are modeling the LNAPL surface floating on top of the groundwater surface. In areas where the LNAPL is absent, RockWorks searches the entire project area for data. To restrict the LNAPL surface to the area that has data, model it separately and specify a Max Distance filter in the Additional Options section of the Gridding Options menu. Another option is to use Polygon Clipping to clip the RwGrd file to the inside of a polygon. Create a Polygon Table with the XY coordinates of the polygon boundary, then choose the Utilities Grid | Filters | Polygon Clip menu to clip the LNAPL grid. You could also try a different modeling algorithm, such as Triangulation, that restricts the surface to the convex hull surrounding the data. Regards, Tom B RockWare Inc
  3. Programming suggestion for striplogs

    Hi David, Copying orientation data to the zero depth is useful for your data, but this procedure may introduce errors for other sources of orientation data. I will add your request for this option to the suggestion file. Regards, Tom B RockWare Inc
  4. Hi Kahn, Use the Aquifers | Model menu command in the Borehole Manager to plot the aquifers as surfaces. Save the RockPlot3D .Rw3D file, then append the Lithology fence diagram. You may want to turn off the sides and bases of each aquifer to make the diagram less cluttered. Regards, Tom B RockWare Inc

  7. Striplogs in profiles...multiple bar charts

    Hi David, I-Data values for different data types do not have to have the same "from-to" depths. They can cover any interval. Regards, Tom B RockWare Inc
  8. Importing DEM

    Hi Katherine, Using UTM or State Plane is better than decimal degrees for vertical plot scaling, distance, area, and volume calculation. Regards, Tom B RockWare Inc
  9. Importing DEM

    Hi Kat, Thanks for sending the files. DEM.txt has the format: ELEV_M <tab> LONG <tab> LAT Import this file into the RockWorks Utilities datasheet. Right-click on the gray column headers to define DEPTH as Z meters and LONG and LAT as X or Y Decimal Degrees. Convert the Lat/Long to your project coordinate system, e.g. UTM Zone 13 m. Scan the datasheet to change the project dimensions if needed. Use the Map | Grid-Based Map menu to make a RockWorks RwGrd file and 2D and 3D maps. PA_069418005_POINTGRID_ZOOM.txt has the format: OBJECTID <tab> pointid <tab> grid_code <tab> ELEV_FT <tab> ELEV_M <tab> LONG <tab> LAT Follow the instructions above to get a RockWorks RwGrd file. Regards, Tom B RockWare Inc
  10. Importing DEM

    Hi Kahn, It sounds like your DEM is not in the specified DEM format. You are welcome to send your file to [email protected] and we'll take a look to see if we can identify the format and recommend a conversion procedure. Include the Input Format that you select, and any information you have about your file. Regards, Tom B RockWare Inc
  11. Citing RockWorks

    Hi Ehsan, Usually the journal where the paper is published has a style guide, but here is an example from the web page "How to Cite Software APA Style" and the nova.edu page "How to Cite Sources: APA Style". Regards, Tom B RockWare Inc. RockWorks17 (Revision 2019.7.30) [Software]. 2019. Golden CO USA: RockWare, Inc.

  12. Horizontal scaling of 2D StripLog section

    Hi Jan, To prevent the logs from overlapping, decrease the width of the columns in the 2D Striplog Designer Column Layout for each item or change the Borehole Spacing to Uniform (Constant) Distance. Regards, Tom B
  13. Ternary Diagrams

    Hi Alison, It looks like your cell size is pretty big, resulting in a low resolution grid of about 10 cells in each direction. I used a cell spacing of 10, resulting in 101 cells in the X direction and 87 cells in the Y direction. . Compare contour maps with different grid cell spacing / size / number. Regards, Tom B RockWare Inc
  14. Ternary Diagrams

    Hi Allison, To contour the Plasticity values in your ternary diagram, Digitize the points XY locations on the diagram and copy to the Utilities datasheet. Create a grid and contour map. Draw a polygon that matches the triangle axes on the ternary plot. Click on it to select it, then right-click and Save to Polygon Table. In Utilities, choose the Grid | Filters | Polygon Clip menu command and replace the values outside the triangle with NULL values. Overlay the ternary plot axes and points as needed. Regards, Tom B RockWare Inc
  15. USGS Lithology Symbols as pattern file?

    Hi acuesta1395, We do not know of any LogPlot pattern files that incorporate the USGS patterns and symbols, but your can create your own patterns with the pattern editor. You can add a background image of the pattern and trace it with the drawing tools in the pattern editor. Regards, Tom B RockWare Inc
  16. 3D buffer

    Hi Ehsan, One way to create a buffer around a fault ribbon is to: Convert the ribbon to a 3D solid to fill the ribbon with points. Extract the XYZ points in the solid. Initialize a new solid filled with 1's. Use the Solid Distance Filter to set values in the new solid to 0's when located the specified distance from the original fault ribbon XYZ points. I'll be happy to post specific instructions upon request. Regards, Tom B RockWare Inc Blue fault ribbon surrounded by red solid voxels at specified distance from fault ribbon.
  17. Hi tdvw, You may be able to use the Triangulation gridding method to better represent discontinuities in the section. Note the pinchout of the blue unit below. . Triangulation produces angular contours, so it is not the best choice for a contour map. The Stratigraphy grids can be filtered with a polygon, but filtering may create gaps with adjacent formations. Regards, Tom B RockWare Inc
  18. Well Construction in Lithology Sections

    Hi Kahn, When you specify non-zero inner and outer diameters for Well Construction data, RockWorks plots duplicate patterns to visualize the borehole. For example a bentonite pack is shown duplicated along the centerline of the borehole with a blank space for other objects such as a well screen. . Regards, Tom B RockWare Inc
  19. Volume calculations

    Hi Jose, Sorry, but I cannot duplicate your results with the Isosurface or Voxel models. I get the predicted results with the manual calculation. You are welcome to send to [email protected] your .RwMod files and the .RCL files saved with the hammer and wrench icon in the upper left corner for each run and I will take a look. Larger files may be uploaded to https://rockware.com/upload Regards, Tom B RockWare Inc
  20. Volume calculations

    Hi Jose, What method are you using to calculate the model volumes for each G value? For example, using the volume reported in the model properties in RockPlot3D, I found that setting a Filter from 1 to 2 includes voxels with values of 1 or 2 for a volume of 1600 , but setting the Filter from 2 to 2 gives a volume of 800. Some other things to consider: Well #2 at (0,10) puts it in the middle of the west side of the area. Did you mean to put it at (20,0) in the SE corner? What modeling method are you using? With no data in the SE corner, values are estimated from the other more distant wells. Some of the cells show a gradation from 1.0 to 1.2. 1.4, ... 2.0 near the edges with the Inverse Distance Anisotropic method. You may want to use the Closest Point method for less interpolation between values in the wells. What modeling options are you using? For example, the Superface filter truncates the model based on a grid of the well elevations. Since the grid elevation coincides with the well elevations, some cells may be nulled out. Turn off this feature for this exercise. RockWorks calculates volumes by counting the number of voxels or cells, and multiplying by the volume of each voxel. When the model is drawn, the model is truncated at the edges to match the project limits when drawn using the Solid style. The model extends past the project limits when drawn with the Voxel style since the center of the voxels are placed at the edges of the model. In both cases the volume reported is the same.

  21. Create 3D grid - topography

    Hi Laure, To display a line on a cross-section representing a surface, create a grid .RwGrd file of the surface from 3 or more points, or from Stratigraphy or Aquifers in the Borehole Manager. Specify the name of the grid file in the Section menu Plot Surface Profile option. Generating a grid file can take a long time if there are a lot of nodes in the grid. If you run out of memory, your computer can crash. You are welcome to send to [email protected] a backup ZIP file of the project generated with the Borehole Manager File | Backup Database command. Include your RwDat or other file used to calculate the topography and the full text of any error messages displayed when the computer crashes. Larger files may be uploaded to https://rockware.com/upload Regards, Tom B RockWare Inc
  22. Creating a 3D model from cross sections

    Hi Ehsan, You can digitize XYZ points on the 3D display, and create models from the digitized points in Utilities. Regards, Tom B RockWare Inc
  23. "Point Sample" tool for rockworks

    Hi Lionel, There are several tools in RockWorks 17 that you can use to extract data from your models. Create new boreholes where you propose to drill piles and choose the Stratigraphy | Section or Lithology | Section menus to draw cross-sections to visualize the data from your models. Use the Utilities Grid | Grids -> Stratigraphic Logs menu to extract Stratigraphy data to the new boreholes. Turn off the existing boreholes so they are not changed. Use the Utilities Grid | Statistics | Residuals menu to extract the elevation from a Stratigraphy grid at the specified XY locations. Use the Borehole Manager Striplogs | Pick Lithologic Intervals menu to pick Lithology units on a cross-section and add them to the borehole Lithology table. Use the Utilities Solid | Statistics | Residuals menu to extract the Lithology G-values at the specified XYZG locations. Regards, Tom B RockWare Inc
  24. Hi Anselme, Unfortunately, your version of RockWorks 16 appears to be an invalid license. Send me your RockWorks 16 registration number from the Help | About menu to get a valid license. You are welcome to download the trial version for RockWorks 17 and use it for 2 weeks. RockWorks 17 includes the WGS-84 datum for UTM projections. Click on the following link for videos for RockWorks 17. Regards, Tom Bresnahan RockWare Inc
  25. Temperature In the borehole

    Hi Nikos, Enter your borehole locations, elevations, and total depths in the Borehole Manager Locations table, and enter the depths and temperatures in the P-Data or I-Data table. P-Data is "Point Data" with one depth per temperature value, and I-Data is "Interval Data" with a top and bottom depth for each temperature value. Create a solid model from the P-Data or I-Data | Model menu and specify the DTM grid as the upper truncation surface or Superface. Regards, Tom B RockWare Inc
