Data Configuration - Borehole Location

Usage Instructions

Drill hole location data records the basic spatial position and depth information of each drill hole, serving as the foundation for loading subsequent drilling data such as drill hole trajectories and stratigraphy.

In the Data Configuration dialog, you can select the Drill Hole Location data type, add a *.hed location file, and configure the internal data fields, external data column positions, and import flags using the Data Field Configuration table. The bottom of the dialog provides a file preview for checking whether the column positions match the file content.

Application Scenarios

  • Establish a project drill hole inventory and spatial positions.
  • Provide a basis for matching drill hole names in data such as drill hole trajectories, stratigraphy, and breakpoints.
  • Locate drill hole data in the structural modeling workflow.

Functional Conditions

  • The project area has been set up, and a data source for storing project data has been specified in the Geological Modeling tab.
  • A drill hole location file is prepared, commonly in *.hed or *.txt format.
  • The location file must contain fields such as drill hole name, wellhead coordinate X, wellhead coordinate Y, wellhead elevation, and bottom hole depth. The column positions of these fields should match the file preview content.

Feature Entry

  • Geological Modeling tab -> Configuration group -> Data Configuration button -> Drill Hole Location on the left side of the Data Configuration dialog

Operation Instructions

  1. In the Geological Modeling tab, after completing the geological modeling project data source settings and project area configuration, click the Data Configuration button to open the Data Configuration dialog. Select Drill Hole Location from the data type list on the left to configure drill hole location data.
  2. Select Drill Information File (*.hed)|hed from the file type dropdown menu. Add the *.hed files to be imported. Multiple location files can be added at once; the file list will display the paths of the files to be imported. To remove a file, select it in the file list and use the delete button.
  3. In the Data Field Configuration table, configure the drill hole location data fields, including Drill Hole Name, Wellhead Coordinate X, Wellhead Coordinate Y, Wellhead Elevation, Top Depth, Bottom Hole Depth, Drill Hole Category, Drill Hole Type, and Owner.
    • Based on the column positions in the bottom preview table, set the corresponding External Data Column Position for key fields. For example, map Well_Name to Drill Hole Name, map X and Y to Wellhead Coordinate X and Wellhead Coordinate Y, map Kelly_Bushing to Wellhead Elevation, and map Well_Top_Depth and Well_Bottom_Depth to Top Depth and Bottom Hole Depth.
    • Check the fields to be imported in the Import column. Drill hole name, wellhead coordinate X, wellhead coordinate Y, wellhead elevation, and bottom hole depth are key fields for location import.
    • Depending on the data content, you may optionally import additional fields such as Top Depth, Drill Hole Category, Drill Hole Type, and Owner.
      Field Description
      Drill Hole Name Unique name or number of the drill hole.
      Drill Hole Category Includes vertical, inclined, horizontal, etc., and can be used as classification criteria.
      Drill Hole Type Includes oil, gas, water, dry, etc., and can be used as classification criteria.
      Wellhead Coordinate X X coordinate of the drill hole wellhead.
      Wellhead Coordinate Y Y coordinate of the drill hole wellhead.
      Wellhead Elevation Altitude of the drilling platform or kelly bushing elevation.
      Top Depth Measured depth from the drilling platform to the start of the drill hole section, typically 0.
      Bottom Hole Depth Measured depth from the drilling platform to the end of the drill hole section, i.e., the drill hole depth.
      Owner Optional additional data.
  4. In the bottom preview table, check the file column names and field content to ensure that the column positions, field names, and data values match the configuration.
  5. After confirming that the file and field configuration are correct, click OK to import. To cancel the current configuration, click Cancel.
  6. After the drill hole data import is complete, the system will prompt whether to extract the project area based on the imported drill hole data.
    • Click OK to extract the project area based on the imported drill hole data.
      • After confirmation, check the current project area in the area settings panel on the right, including Left, Bottom, Right, Top, Minimum Elevation, and Maximum Elevation.
      • After confirming the area is correct, click Save and Apply to save the project area to the current project.
    • Click Cancel to retain the current project area settings.
Notes:
  • The drill hole name, wellhead coordinates, wellhead elevation, and bottom hole depth must have valid external data column positions; otherwise, the location data cannot be imported correctly.
  • When importing a drill hole location file, ensure that the corresponding columns are correctly matched with the data fields, and verify that the column names and sample data in the preview table match the configuration.
  • Drill hole category and drill hole type are primarily used as classification criteria and have no actual modeling meaning in the geological modeling workflow.
  • Both top depth and bottom hole depth are measured depths. Before importing, confirm that the depth units are consistent with the project data.
  • The default drill hole type is UN if missing, the default drill hole category is X if missing, the default top depth is 0 if missing, and the default owner is UN if missing.
