How should I organize my well data to import it into Voxler?

To display your wells and sample data with the WellRender module, you will import a combination of collars information (X, Y, Z location of the well tops), log data, and trajectory information. Voxler uses measured depth values to plot the wells, and you can either import your data as multiple sheets containing collars, trajectory, and sample data - or as a single sheet with pre-computed down-the-hole X, Y, and Z values.

In order for well traces to be displayed, the WellData module needs to contain valid well paths. For a well to have a valid path, one of the following needs to be true:

  1. The data is imported with azimuth, dip, and measured depth.

  2. The data is imported with directional survey information. A path is then computed automatically.

  3. The data is imported with pre-computed X, Y, and Z values down-the-hole.

Log ASCII Standard LAS files and non-tabular format data files will be imported directly into the WellData module.


Multiple table approach with directional survey information

Trajectory information may be organized is using a collars table, directional survey table, and samples table. With this approach, each table is on its own sheet in a workbook or in separate files. To use this approach, the following data is required: 


Collars Table

Directional Survey Table

Log/Samples Data

Well ID/Name

Well ID/Name

Well ID/Name

Top Easting (X) Location

Measured Depth

Log/Sample Data

Top Northing (Y) Location


Measured Depth (or From and To columns)

Top Elevation (Z) Location



Total Measured Depth




The three sheets contained in the SampleWellData.xlsx file (located by default at C:\Program Files\Golden Software\Voxler 4\Samples) are an example of data organized in this way.
