How to import a crooked section creating in a Geosoft application into Leapfrog Geo.

Joe McPherson

Objective:

I have created a crooked section in my Geosoft applications and would like to display it in Leapfrog Geo.

Resolution:

The current release of Leapfrog Geo does not support crooked sections, you will need to convert the crooked section into a file format supported by Leapfrog Geo. There are two methods we will explore in this article:

  1. Converting the crooked section into a "thin voxel" and then importing that into Leapfrog Geo using an OMF file. 
  2. Converting the crooked section into a "thin voxel", then converting the voxel into a GOCAD Voxet, and importing the voxet into Leapfrog Geo. 

Both workflows start with a "thin voxel" so lets cover this workflow first. To create a "thin voxel" from a crooked section, you will need to first save the crooked section to a database, and then 3D grid the database into a voxel.  

Converting a crooked section into a "thin" voxel:

  1. Convert the crooked section into a Geosoft database (*.gdb) by going to Image > Utilities > Export Grid to Database.
    • NOTE: be sure to set the Decimation Factor in both directions to 1
    • This will save the X,Y,Z and data values from your section grid into a Geosoft Database (*.gdb)
  2. Then create a new voxel from the database by going to Voxel > New > Kriging. 
    • Select the data channel and give the output voxel a name. 
    • You will likely need to reduce the cell size to obtain a finer resolution as the default size will likely be a little to course. 
    • You may also want to consider lowering the Blanking Distance in the Advanced parameters. 

Once you have a "thin" voxel your happy with, you can move onto one of the following workflows. 

Option #1: Export the voxel in a OMF file and import it into Leapfrog Geo

Exporting a voxel to an OMF file:

  1. Create an empty 3D View by going to 3D View > New.
  2. Add the voxel into the 3D View by going to Add to 3D > Voxel
  3. Export the voxel by going to Export > OMF file 

Import the OMF in Leapfrog Geo:

  1. In Leapfrog Geo go to Leapfrog Geo > OMF > Import 
  2. Select the OMF file and click Open

Option #2: Convert the voxel into a GOCAD Voxet and import it into Leapfrog Geo

Converting a Voxel into a GOCAD Voxet:

  1. Voxel > Conversions > Voxel to GOCAD
  2. Select your voxel, give your output voxel a new name, and set the orientation.
  3. Press OK

Displaying the GOCAD Voxet in Leapfrog Geo:

  1. On the Project Tree select the Geophysical Data folder and click Import GOCAD Model 
  2. Select the GOCAD model (*.vo) and click Open
  3. In the Import Gocad Model dialog set the Subsample Rate and click OK
  4. To display the imported GOCAD model, select it in the Project Tree and click View Object
