Exporting a Horizon

Horizons can be exported to text or GEOH5 files. The file structure of the text files depends on the selected format, but in general each row of the output file corresponds to a point on the horizon.

By default, Insight will save horizons in the 120hors sub-folder.

Note: For more information on exporting horizon files, see Horizon Export File Formats.

Types of horizon export

  • Base horizon: a text file containing rows of location and time or depth for a single 2D or 3D survey, or X/Y. It does not include additional properties.
  • Complete horizon: (All properties, multi-survey) a complete horizon containing location, time (or depth), and any additional custom properties, for one or more 2D and 3D surveys.
  • Customised horizon: a text file containing rows of location, time, depth, and custom properties, selected by the user.
  • GEOH5: A data exchange format for geoscience data in the minerals (mining) industry. Exporting multi-Z horizons to GEOH5 is currently not supported.
  1. In the Control Panel, open the Horizon tab.
  2. Right-click on the 2D or 3D horizon to export and click Export 'Horizon'.
  3. The Export 'Horizon' window will be displayed.

Exporting a base horizon

The export base horizon option is only available for 3D horizons.

  1. Select Export base horizon in default Insight text format.
  2. Click OK.
  3. Type the file name to save as .ilclt (time-domain) or .ilclz (depth domain) format.
  4. Click Save.

Tip: If the horizon extends to multiple surveys, select Export all properties in Insight multi-survey format.

Exporting a complete horizon

  1. Select Export all properties in Insight multi-survey format.
  2. Click OK.
  3. Type the file name to save in .dugmsh format.
  4. Click Save.

Exporting a customised horizon

Export 2D horizon to a customised text file
  1. Select Export customised text file.
  2. Click OK.
  3. The Export Horizon window will appear.
  4. Tick the checkbox of the field to be exported.
    • Line name and Shot (2D horizons)
    • IL/CL (3D horizons)
    • X/Y coordinates
    • Time/Depth domain
    • Custom horizon properties
  5. To change the order of the fields, click and drag the dotted area to the left of the field name.
  6. Click OK.
  7. Type the file name to save in .dat format.
  8. Click Save.

Note: A different vertical domain can be selected during export if the time-depth conversion is configured.

Exporting horizon to a GEOH5 file

  1. Select Export horizon to GEOH5 file format.
  2. Click OK.
  3. The Export Horizon window will appear. Insight will automatically open the project folder. Select the directory where you want to export the horizons and click Save.
