  1. If your data are collected by linear scanning, you may be able to use the scan number as the Y, the index of each point in each scan as the X, and the deformation as the "Z" value to make a "flat" gridded surface, then calculate the deformation along the surface of the tunnel. This method requires that the data are listed in the order of recording or collection. The time index may also be used instead. To visualize this method, imagine draping a tarp over the top of the data points, getting a copy of the deformation value at each point, then laying the tarp on a flat surface.
  2. You may be able to filter the data by elevation to create a grid of the top data. Next split the sides data by X coordinate running through the center of the tunnel. Grid the sides as if they were horizontal by switching the Y and Z coordinates. The side tunnels at the front may have to be split further. Regards, Tom B
  3. Hi Msmisitel, I suggest plotting the XYZ points with the RockWorks 2020 with the Utilities 3D | Points menu command. Use the G value in the Style | Advanced | Size & Color | Color | Proportional menu to set the color of the point proportional to the G value. A gridded surface created with triangulation or other methods probably won't work because it requires a single Z value at each XY location. You may be able to grid the top and bottom of the tunnel separately if you can split the data set. Regards, Tom B RockWare Inc
  4. Hi Nicooh, Here are a few general tips to help resolve the problem. For more specific advice, backup your project with the File | Backup Database menu and send us the ZIP file. Check your boreholes to make sure you have formations listed down to the total depth of the borehole. Use the Strat Picker in the Striplogs menu to add missing formations. Increase the grid cell spacing in the project dimensions for a higher resolution grid. Turn on the option for High Fidelity to make sure your Stratigraphy model honors your data. Turn off the options for Smo
  5. Gridded surfaces can include use strike and dip information when you create the grid. Choose the ModOps Grid | Create | XYZ & Dips -> Grid menu. Sold models require XY location, Z elevation (ground minus depth), and G (a unique numeric ID) of each node within the item. Regards, Tom B RockWare Inc
  6. Hi Vincent, Please backup your project with the File | Backup Database, and send the ZIP file to Support@rockware.com. We'll take a look to see how to resolve the problem. Regards, Tom B RockWare Inc
  7. Hi Craig, 1. It sounds like the grids in the Stratigraphy model that you are using for volume calculation do not represent the surfaces very well. Check for errors by creating contour maps of the upper and lower surface with the well data to check the models against the data. Use Grid Math to subtract two surfaces to get a thickness contour map plotted against the well data. Change the gridding algorithm and other options to change the Stratigraphy model grids. 2. This one sounds like the ground surface grid was replaced with the basement grid. Regenerate the ground sur
  8. Hi Vincent, Option 3 may be your best option to begin with. Since you do not know the base of A or the top of B, leaving both blank with allow RockWorks to estimate the depths for both when creating a Stratigraphy model by using the nearby boreholes. A more rigorous approach is to use the Strat Picker (Striplogs | Pick Stratigraphic Contacts), which displays a cross-section view so you can estimate the base of A and the top of B and add those depths to the Stratigraphy database. RockWorks does make a distinction between your three options listed
  9. Hi Jiawei Li, To make a contour map of percentage lithology at each XY location on the map, follow the RockWorks 2020 instructions below. Create a Lithology model from the borehole data. Open the Lithology Types table from the Lithology tab or the Project Manager | Project Tables. Choose File | Export to Datasheet. Close the Lithology Types table. In the Borehole Operations section, choose Lithology | Lithology/Stratigraphy By XY. Specify the Data Columns | G-Value as in the column
  10. Hi Amirul, The missing Stratigraphy layers may not show if they are very thin, or if using a Modeling Sequence that allows layers to truncate overlying layers where they intersect. In addition, check that the order of the Stratigraphy units remains the same in all boreholes, and that missing units are inserted with a zero-thickness in the Stratigraphy table. You are welcome to backup your project with the File | Backup Database menu and send the ZIP file to support@rockware.com and we will pursue your question further. Larger files may be uploaded to https://rockware.co
  11. Hi Mike, Another way to create a grid on the top of multiple Lithology types is to export the Lithology to Excel, then import the Lithology to the Stratigraphy table. Delete the different bedrock lithology types in the Stratigraphy Types table and merge them into a single Stratigraphy unit, then create a grid with the Stratigraphy | Single Surface menu. Regards, Tom B RockWare Inc
  12. Hi Vincent, Thanks for letting us know that you found a solution. Regards, Tom B RockWare Inc
  13. Hi Vincent, I have good luck with ReportWorks printing to CutePDF at 2400dpi and 4000 dpi. If problems continue, you are welcome to send a backup of your project, your Rw2D and PDF files to support@rockware.com and I will take a look Regards, Tom B RockWare Inc
  14. JamesH, Regarding your lithology map question: Create lithology map from a lithology model RwMod file and a gridded surface RwGrd file with the Borehole Manager Lithology | Surface Map menu. If you have truncated the Lithology model with the ground surface (superface filter), and you are using the same ground surface for the Lithology Surface Map, you may need to subtract the value of the model Z spacing. The ground surface and lithology model do not overlay exactly due to the size of the lithology model voxels. If you imagine placing a board on a flight of stairs, you
  15. JamesH, I suggest using the Striplogs | 2D | Section and Striplogs | 3D | Multiple Logs to look at your Stratigraphy data. Only a few of your boreholes have the Proterozoic unit, and they are at a higher elevation relative to the base Paleozoic in the boreholes on the east side of the project. If you make grids of this unit, RockWorks does not have the control points for this unit in the wells where it is missing, so it uses the existing data to project the unit at a high elevation. Add Proterozoic tops to boreholes to control the surface. .
