Drillhole data is a key content type in LiquidEarth, commonly used in geological modeling, resource exploration, and subsurface analysis. Depending on the industry, application, or software, drillholes may also be referred to as boreholes or wells. They represent boreholes drilled into the ground, containing depth-related information such as lithology, geophysical measurements, and structural data.

Importing Surface Meshes

• The currently supported format for drillhole data is CSV. See Import Formats for all currently supported formats.
• Drillhole data is imported via the Data Import Wizard.

Drillhole Components & Attributes

Drillholes in LiquidEarth consist of the following key components:

• Collar – The starting point of the drillhole at the surface, represented by an indicator.
• Path – The trajectory of the drillhole, typically defined by deviation survey data.
• Attributes – Data recorded along the drillhole, such as:
  • Lithology (rock types and formations)
  • Geophysical measurements (e.g., gamma values, magnetic susceptibility)
  • Assay results (e.g., mineral grades)

Each drillhole can be visualized using Drillhole Colormaps, where attributes are mapped to color for better interpretation.

Drillhole-Specific Features

For features specific to this data type, such as how to adjust the way drillholes are vsiualized, see Drillhole Inspector.

Use Cases

Drillhole data is widely used in:

• Geological exploration – Identifying subsurface rock formations and structures.
• Mining and resource assessment – Evaluating ore grades and deposit models.
• Geotechnical engineering – Analyzing ground stability and subsurface properties.
• Hydrogeology – Investigating groundwater conditions and aquifers.
