RockWorks | Borehole Manager | T-Data | Plan Map
Use this program to:
- Create a new 3-dimensional solid or block model representing your downhole time-based interval data (an .RwMod file) - OR - read an existing .RwMod file you've already created.
- Create a 2-dimensional map representing the interpolated values where the model intersects a horizontal plane.
The horizontal slice will be stored as an .RwGrd model in your project folder. Standard color- and line-contour options are available. The completed map is displayed in RockPlot2D.

Step-by-Step Summary
Tips
Menu Options
- Solid Modeling Options: First, tell the program whether you wish to use an existing solid model (from a previous use of this tool or another T-Data menu tool) or you wish to create a new solid model, by clicking in the appropriate radio button.
! Note This is not trivial. Creating the solid 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 profile diagram, for example, you can use the same model, which was stored on disk as an .RwMod file, for the model from which the plan-view will be extracted.
- Create New Model: If want to create a new model, click in this radio button, and expand this item to establish the modeling settings.
- T-Data Track: Click on this item to select the track or column in the T-Data tab that is to be modeled. The names displayed in the list will be pulled from the column headings. Expand this option to establish any source data filtering.
! Note that these tools filter the data that is passed to the modeling procedures. This is distinct from the filters that are applied after the model is completed (see Other Modeling Options below).
- Filter Based on G-Values: Activate this option to establish a data filter based on the measured values (geochemistry, etc.), and expand the heading to establish the filter parameters. (More.)
- Resample at Regularly-Spaced Intervals: Check this box to resample the data. (More.)
- Date/Time Filter: Insert a check in this box - on the far right side of the current program window - to model measurements for a specific date or range of dates. If you leave this un-checked the program will model all of the measurements, for all listed dates, in a single model. (If you have entries for different dates for the same depth intervals for your wells, leaving the date filter off may not make much sense.)
- Exact: Click in this button if you wish to enter a specific date for the measurements to be modeled. Enter into the prompt or choose from the calendar the specific date. During modeling RockWorks will process the T-Data measurements for the selected track that fall on this date.
- Range: Click in this button if you prefer to enter a beginning and ending date to define the range of dates to be included in the model. Type the dates into the Start and End prompts or pick dates from the calendar. During modeling RockWorks will process the T-Data measurements for the selected track that fall within this date range.
Spatial (XYZ) Filtering: Insert a check in this box - also on the far right side of the current program window - to activate a data filter based on where the data points lie. Expand this heading to establish the filter settings.
- Create Filter / Sampling Report: If you've selected any filter/resampling options, this tool will create a summary report of the results. (More.)
- Solid Model Name: Click to the right to enter a name for the solid model, with an .RwMod file name extension.
! It's a good idea to incorporate the date into the name of the model, if you're creating multiple models. For example, "cobalt_02-14-07.RwMod" could be the model for the Feb 14, 2007 measurements of cobalt, and "cobalt_08-06-07.RwMod" for the cobalt model for August 6th.
- Solid Modeling Options: Click on this button to establish important modeling settings:
- Algorithm (Modeling Method): This determines the modeling method to use, for creating a solid model from your irregularly-spaced drill hole data. (More.)
- Model Dimensions: This determines the model density. (More.) Unless there's a specific reason to do otherwise, you should probably leave the solid model dimensions set to the current output dimensions.
- Other Modeling Options: These include tilting, warping, filtering above-ground, smoothing, and much more.
- Use Existing Model: Click in this radio button if you wish to use an already-existing solid model of your time-interval data. Expand this item to select:
- Model Name: Click to the right to browse for the name of the existing solid model from which the plan grid will be extracted.
- Output Grid: Click here to type in the name to assign the output grid (.RwGrd) that will be created as a result of extracting a specific slice from the solid model. This grid model's nodes will represent the solid model node values as they appear at the selected elevation. (You'll choose the elevation level after setting up the menu options.)
- Diagram Settings:
- Background Image: Check this box to display a raster image behind the contours, and expand this heading to set the image options. (More.)
- Contour Lines: Check this box to display the T-Data values using line contours. Expand this heading to access the contour options. (More.)
- Colored Intervals: Insert a check here to include color contours to represent the T-data values, and expand this heading to access the various options. (More.)
- Labeled Cells: Check this to include a map layer that displays the solid model node values as labeled cells; expand the heading to adjust the layer's settings. (More.)
- Borehole Locations: Insert a check in this box to display the borehole locations with map symbols, with a variety of labeling options. Expand this heading to access the symbol & label settings. (More.)
- Border: Check this to include a map border, and expand this heading to adjust the border options. (More.)
Step-by-Step Summary
Follow these steps to create a 2-dimensional map that displays the modeled T-data at a user-specified elevation:
- Access the RockWorks Borehole Manager program tab.
- Enter/import your data into the Borehole Manager. This tool specifically reads location, orientation (if any), and Time-Interval or "T-data."
- Select the T-Data | Plan Map menu option.
- Enter the requested menu items, described above
- Click Continue to proceed.
If you've selected Use Existing Model, the program will load the information from the existing T-Data 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 XYZ points for all of the downhole measurements for the selected T-Data track. (For T-Data, the elevations will represent interval midpoints.) It will apply any source data filters you have requested.
- If you requested Confirm Dimensions, the program will first prompt you to confirm the default solid model dimensions. (More.)
- The program will then display a window listing all of the elevation levels in the solid model. Choose the elevation to be represented in the plan-view map, and click OK.
The program will use the selected algorithm to create a solid model of the downhole time-based interval data. The completed model will be stored on disk under the indicated file name.
The program will extract the selected layer from the solid model, saving it as a 2D grid model under the specified file name, and create the 2D map using the requested diagram settings. The completed map will be displayed in a RockPlot2D tab in the Options window.
- You can adjust any of the modeling or diagram options in the pane to the left and then click the Process button again to regenerate the T-Data map.
! Each time you click the Process button, the existing map display will be replaced.
! * If the T-Data 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 .RwMod file to be used for the map.
- View / save / manipulate / print / export the image in the RockPlot2D window.
Tips:
- Use the Utilities Grid | Filters | Range to filter the plan-slice grid model that this tool generates for a specific value range, and run the filtered .RwGrd file through the Grid | Statistics | Report tool to determine area.
- Another way to view a horizontal slice within a solid model is via the T-Data | Model option. Once the isosurface or voxel model is displayed in RockPlot3D, access its Options window and insert a horizontal slice. This slice can be moved up/down interactively within the solid.
- Double-click on the plan map in RockPlot2D to access the colorfill settings. There, you can adjust the minimum contour level, transparency, etc.
