Create Lithology Fence Diagrams

RockWorks | Borehole Operations | Lithology | Fence

Use this program to:

• Create a 3-dimensional solid model representing interpolated lithology types (an. RwMod file)
  - OR -
  Read an existing lithology .RwMod file you've already created, and
• 
  
• "Slice" this model along multiple panels and create a 3D fence panel diagram. Because the model is interpolated across the entire project, you can place the fence panels anywhere you like.

You may request regular panel spacing, in a variety of configurations, or you can draw your own panels. The lithologies will be represented in themodel using the numeric "G-values" declared in the Lithology Types Table. The lithologies will be represented in the diagram using the background colors defined for the patterns in the Lithology Types Table. 3D logs can be added to the image if desired. The completed fence diagram will be displayed in RockPlot3D.

Feature Level: RockWorks Standard and higher

Menu Options

• Rules & Filters: Use the buttons at the top of the window to apply filters and rules for this program. (More info)
  • Spatial Filter: Filter the input data for the lithology model based on XYZ location, filter the data to be displayed in striplogs, if activated. Note that these tools filter the data that is passed to the modeling and log-generating procedures. This is distinct from the filters that are applied once the model is completed, and described below.
  • Time Filter: Filter any T-Data or Aquifer data in striplogs, if activated.
  • Stratigraphic Rules: Apply stratigraphy rules for Stratigraphy data in striplogs, if activated.
  • 
    
• 3D Log Design
  Click here to choose which data items are to be displayed in the logs, if activated via the Striplogs checkbox below, and in which order. See Using the 3D Log Designer and the Visible Item Summary.
• 
  
• Fence Location
  Click on this button at the top of the window to draw, on a map display of your enabled boreholes, where the fence panels are to be placed. The most recent fence drawn for this project will be displayed (More info)
• 
  
• Location Map
  Insert a check in this tab, at the top of the window, to create, along with the fence diagram, a reference map that shows the fence panel locations.
  Click on this tab to set up the map options. (More info)

• Model
  Click this tab to define whether you want to create a new lithology solid model or you wish to use an existing lithology solid model (from a previous use of this program or another Lithology menu program), by clicking in the appropriate radio button.
  ! NOTE ! This is not trivial. Creating the lithology model can take some time, depending on the resolution of the model and the detail of your data. If you already created a pleasing model for display as a 3D voxel diagram, for example, you can use the same model, which was stored on disk as an .RwMod file, for the fence diagram.
  
  • Create New Model: To create a new model for the diagram, click in this radio button, and use the tabs to the right to establish the modeling settings.
    • Solid to be created: You may use the default program-assigned name, or click to the right to enter a different name for the lithologic model, such as "lithology". The program will append automatically the file name extension ".RwMod".
    • Create Filtering/Resampling Report: Check this item to generate a text report of the results of any spatial filtering you applied.
    • Limit Input: Check this box to activate an input data filter based on material type. Click on the tab to enter the filter settings. (More info)
    • Limit Output: Check this box to filter the output model based on material type. (More info)
    • Algorithm: Click this tab to select the modeling method to use, for interpolating your lithology model. (More info)
    • Special Options: Click on this tab to establish other model settings, such as tilting, warping, filtering above-ground, and smoothing. (More info)
    • 
      
  • Use Existing Model: If you wish to use an already-existing lithology model, click in this radio button.
    • Solid Model: Browse for the name of the existing lithology model (.RwMod file) to be used for this fence diagram.
    • 
      
• Panel Borders
  Check this box to include a solid-line outline around each fence panel.
  Click on this tab to define the line style and color.

• 

  
  
• Surface Profile
  Insert a check here to include a solid line profile on each fence panel that represents a user-selected grid model, typically the ground surface.
  Click on this tab to select the grid model to be represented in the fence diagram, and to establish the profile settings. (More info)

• 

• Striplogs
  Check this item to include 3D logs with the lithology fence display. Note that 3D logs for all active boreholes will be appended to the fence diagram.
  Click the 3D Log Design button at the top of the window to set up how you want the logs to look.
  • Clipping Dimensions: Insert a check in the X, Y, and/or Z axis options if you want to restrict the logs to a particular spatial area. (More info)
  • 
    

• 

• Other 3D Diagram Options: Use these checkboxes to append other layers to your 3D scene. (Summary)
  
  • Draped Image: Include an image in this 3D scene, draped over an existing grid surface. (More info)
  • Floating Image: Include an image in this 3D scene, floating at a specified elevation. (More info)
  • Perimeter Cage Include a 3D reference cage around the lithology fence diagram. (More info)
  • Legends: Include one or more legends with the diagram.(More info)
  • Infrastructure: Display buildings, pipes, or other infrastructure with your 3D scene. (More info)
  • Faults: Include 3D fault ribbons with this scene. (More info)
  • Other 3D Files: Include other, existing, RockPlot3D ".Rw3D" files in this scene. (More info)
  • 
    
• Output Options
  
  • Save Output File: Check this to assign a name for the 3D scene in advance, rather than displaying it as Untitled.
    • Automatic: Choose this option to have RockWorks assign the name automatically. It will use the name of the current program plus a numeric suffix, plus the ".Rw3D" file name extension.
    • Manual: Choose this option to type in a name of your own for this RockPlot3D file.
  • Display Output: Check this option to have the resulting scene displayed in RockPlot3D once it is created.
  • 
    
• Include Volumetrics: You can disable this option if the volume computations take too long (e.g. a very dense model) or you simply don't need them.

Step-by-Step Summary

1. Access the RockWorks Borehole Manager program tab.
2. Enter/import your data into the Borehole Manager. This tool specifically reads location, orientation (if any), and lithology data.
3. Select the Borehole Operations | Lithology | Fence menu option.
4. Enter the requested program settings, described above
5. If you are including logs, be sure to click on the 3D Log Design button to establish how you want the logs to look.
6. Click on the Fence Location button to select the fence panel locations.
7. Click on the Continue button to create the lithology fence diagram.

   If you've selected Use Existing Model, the program will load the information from the existing lithology model (.RwMod file), and will proceed to diagram generation.

   If you've selected Create New Model, the program will scan the project database and extract the borehole locations, lithology depths and materials, and any borehole orientation. It will apply any source data filters you have requested, and will interpolate the solid lithology model.

   The program will look at the coordinates specified for each fence panel and determine the closest nodes along the cuts in the brand-new model, if created, or in the existing model. It will construct a vertical profile to illustrate the lithology types, using the rock types' background colors specified in the Lithology Types Table. This process will be repeated for each fence panel you drew. Logs will be appended if requested. The completed diagram will be displayed in a RockPlot3D tab if requested.

8. You can adjust any of settings in the Options tab and then click the Continue button again to regenerate the diagram.

   ! * If the lithology model looks OK and you just need to adjust one of the diagram settings, you don't need to keep re-interpolating the model. Choose Use Existing Model and browse for the lithology .RwMOD file to be used for the fence.

9. View / save / manipulate / print / export the image in the RockPlot3D window.
