Create Drillhole From ELog

This command takes an LAS electronic E-Log and creates a drillhole from it. The maximum density and gamma are used to determine the type of rock or material to assign to each composite. There are default values in the settings folder, and these can be used for initial definitions, but further analysis should be done for individual projects. Not only are the rock types varied for gamma and density, but each individual sensor and logging device gives different readings and value ranges, so this should be used accordingly. The Settings can be saved and loaded for each project and logger.

Once the names, density and gamma and their colors are defined, then select the "Load eLog" button to select the LAS file to import. This will populate the upper right column and show the various rock types colored of the hole. If this looks good, then selecting the "Create" button will place it in the drawing.

 

The Create button will place the drillhole in the drawing. This hole can then be viewed with commands, such as Edit Drillhole. Here is the editor showing the drillhole imported from the above LAS file. The intervals and types of material match what is shown above.
