Drilling data

Driver supports drilling data as a 3D point cloud in the following formats:

• Seequent Evo geoscience objects, specifically downhole intervals that contain numeric attributes, such as assays, and non-numeric attributes, such as lithology codes
• Point data (*.csv), imported from a local file

At a minimum, numeric drilling data must be desurveyed before uploading to Driver. However, for best results, compositing the data and following the steps described in Preparing numeric drilling data for Driver is recommended.

When creating a project using a local *.csv file (UTF-8), data should be formatted to include:

• XYZ coordinate for each sample
• Hole_id or BHID for each sample (optional)
• Any number of numeric attribute columns (e.g. Au_ppm)

A Driver project can have only one drilling data set.

The rest of this topic describes importing drilling data into a Driver project and then displaying it. This topic is divided into:

• Uploading drilling data from Seequent Evo
• Uploading drilling data from local files
• Displaying drilling data
• Drilling spotlight
• Updating drilling data

Uploading drilling data from Seequent Evo

To upload drilling data into a Driver project from Seequent Evo, click on the button to the right of Upload drilling and choose From Seequent Evo:

In the window that appears, all downhole intervals data in the workspace is listed. Choose the drilling data you wish to use and click Import.

Next, choose the attributes you wish to import. Here, the attributes AG_PPM and AU_PPM are selected:

Click Submit to import the data.

Driver will validate the data. Once this is complete, the data will appear in the project tree.

Driver creates a single closed mesh called a bounding box that encloses all samples in a project. When you add drilling data to a new project, the bounding box is added to the Meshes > Closed meshes folder:

Uploading drilling data from local files

To upload drilling data into a Driver project from a local file, click on the button to the right of Upload drilling and choose From local file. In the window that appears, navigate to the location on your hard drive where the file is stored and select it.

The process for uploading drilling data is the same as for uploading from Seequent Evo, except that when choosing the attributes you wish to upload, you also need to map the X, Y and Z columns. A drillhole ID column is optional.

Once you have selected attributes and mapped the required columns, click Submit.

Displaying drilling data

When displaying drilling data in the scene, you can colour the data using any of its columns:

You can also:

• Display a legend (), when one of the data columns is used
• Change the point size used ()
• Adjust the display range ()

Drilling spotlight

Opening the spotlight for a drilling data object will show some basic summary statistics, along with a histogram of the value distribution:

Updating drilling data

When new data becomes available outside your Driver project, update the project by selecting one of the Update drilling options:

Whether you are updating from Seequent Evo or from a local file, you will be prompted to choose the file to use. Once you have done so and chosen which columns to include, click Import. All data objects in the project will be reprocessed.
