Tutorial: Create a Modeled T-Data Profile

Estimated time: 3 minutes.

In this lesson, you will create a single-panel cross section slice using the same T-data model used previously for the isosurface diagram.

! The instructions below are written with the assumption that you have completed the previous lesson, as well as the lesson on log sections.

1. Click on the T-Data Menu and choose Profile.
   
2. Main Options: These settings will set up the model and diagram settings. These are found in the left pane of the T-Data Profile window.
   • Vertical Exaggeration: This should be set to 1.
   • 
     
   • Model: Establish the model settings.
     • Use Existing Model: Since you took the time to create a T-data solid model in the previous lesson, we can use that one for this tutorial.
     • Solid Model: Click here to browse for the file Toluene 2-14-17.RwMod.
       ! This is really important to remember ! In your own work. Once a solid, numerical model is created to represent your data, and saved as an .RwMod file, you can use that same model to create different types of diagrams – profiles, sections, fences, isosurfaces, slices – without having to recreate the solid model each time. Here we just want to create a new type of diagram from the model you already created.

   • Contour Options This tab includes settings that apply to both 2D and 3D grid displays:
   • • Color Bands – Click here to enable colored contour bands and specify a Color Scheme used for 2D Contour Maps or 3D Surface Diagrams.
     • Contour Lines – Click here to enable Contour Lines and specify settings for both 2D and 3D diagrams.
     • Smoothing – Click here to specify Contour Smoothing passes, which will be applied to both the Color Bands and Contour Lines. Note that contour smoothing is applied AFTER grid creation and is a separate step from the Grid Smoothing tools that can be applied during grid creation.

     • 

     • Labeled Cells – Click here to turn on Labeled Cells for 2D Grid Maps. The program will draw a grid of lines corresponding to the grid model nodes, and fill the cells with labels for the node values.
     • Gradient Vectors – Click here to turn on Gradient Vectors for 2D Grid Maps, The program will display small arrows between grid nodes to represent uphill or downhill gradients.
     • 
       
   • Striplogs: Checked. The program will project 2D logs to the section panels. If you want to review the 2D log settings (which you established in for the striplog section) you click on the 2D Log Design tab at the top of the window.
     • Collar Distances: Check this, so that distance from the profile to the projected logs will be displayed.
   • 
     
   • Annotation: Checked.
     • Title: Change the title to read: T-Data Profile A to A'
   • 
     
   • or Plot Surface Profile: This option can be either checked or not, as per the log section lesson.
   • 
     
   • Parallel Profiles: Unchecked.
   • Infrastructure: Unchecked.
   • Other 2D Files: Unchecked.
   • Peripherals: Unchecked.
   • Border: Unchecked.
   • 
     
   • Output Options
     • Display: Checked.
     • Save: Unchecked.
     • Export: Unchecked.
     • 
       
3. Now move to the tabs at the top of the window.
   • Spatial Filter: Unchecked.
   • 
     
   • Time Filter: This should be checked and set to Feb 14, 2017.
   • 
     
   • Strat Rules: These settings will be ignored since we are not plotting stratigraphy data in the logs.
   • 
     
   • 2D Log Design: The striplogs should still be set up as they were for the log section; if you want to review the 2D log settings you can click on the 2D Log Design tab.
   • 
     

     

   • Click on the Profile Location tab to establish where the profile slice is to be placed. Any previous profile trace that you may have drawn in a separate session will be displayed.

   • 

     • Select the profile location:
       • Select the starting point for the profile cut by clicking on the borehole DH-30 near the northwest corner of the project area.
       • Select the endpoint for the profile (you're picking a single slice only) by clicking on the borehole DH-23 in the middle of the eastern side of the project.
       • Be sure that the swath to either side of the slice, within which the logs will be projected onto the diagram, is set to 20, using the prompt at the top of the window. This swath is represented by the yellow cross-hatching, as shown below.

     

   • Location Map: This should still be checked as it was for the log section lesson. To verify the settings, click on the Location Map tab at the top of the window. Be sure it is set to display the map inside the profile diagram.

   • 

     
     
   • Faulting: Click this tab to set up your Faulting Options in your striplog display and to modify fault options. (Read this for more details.)
   • 
     
4. Click the Continue button at the bottom of the window to accept the modeling and diagram options, and the profile location.

   The program will read the existing solid model (Toluene 2-14-17.RwMod) and extract a panel along the indicated profile trace, with the indicated perimeter annotation. The bargraph logs will be projected perpendicularly onto the profile diagram. The map representing the panel trace will appended to the profile. The completed diagram will be displayed in a RockPlot2D window.

5. Use the check-boxes in the Layers pane to the right to turn on/off specific logs (or portions of logs which are projected onto the profile), panels, etc.
   
6. You can save the section if you want, using the File | Save As menu command and entering a name of your choice.
   
7. Close the profile window.
