Comparing Drillhole Endpoint Locations

RockWorks | Borehole Manager | StripLogs | Endpoint Comparison

This program is used is used to generate a listing of the spatial relationships for the borehole endpoints.  It is often used by drilling companies when comparing multiple, complex boreholes.  The output from this program is displayed within a program datasheet.

Step-by-Step Summary

1. Access the Borehole Manager program tab. 
2. Enter/import your data into the Borehole Manager. 
3. Verify that the names of the boreholes to be included in the computations are enabled (the check-boxes to the left of the borehole names are checked).
4. Select the Borehole Manager | StripLogs | Endpoint Comparison menu option. 
5. Establish the computation options, as described above.
6. Click the Process button to proceed with the calculations.  

The program will determine the true 3D location for each active borehole's ending point, and will perform the requested computations.  The results will be listed in a datasheet, embedded to the right of the options list.  The example below shows all of the possible columns. 

Tips

• See the Edit | Adjust Total Depths option if you are not certain that the borehole Total Depth fields (Location table) match the lowest recorded data value for the boreholes.
• Use the File | Save menu to save the report as an RwDat file, or the File | Export menu to export to another format.
