Geophysics Visualisation & Analysis

Easily visualise and analyse borehole wireline geophysical Log ASCII Standard (LAS) files with this interactive tool.

What is a LAS File?

LAS (Log ASCII Standard) files are a standardised format used in the geoscience industry to store well log data. These files contain valuable information about subsurface formations, including physical properties like density, porosity, resistivity, and gamma radiation. LAS files are widely used in mining, oil and gas, geotechnical engineering, and groundwater studies to analyse subsurface conditions and make informed decisions.

Why Use This Tool?

Visualising LAS files typically requires specialised software that can be expensive and complex to use. Our free online LAS file visualiser provides an accessible alternative, allowing you to quickly upload, view, and analyse your well log data directly in your browser.

Key Benefits:

  • No Software Installation: Access and analyse your LAS files from any device with a web browser
  • Interactive Visualisation: View multiple log curves simultaneously with customisable display options
  • Data Table View: Examine the raw numerical data in a structured format
  • Export Capabilities: Download visualisations for reports and presentations

How to Use

Using our LAS file visualiser is straightforward:

  1. Upload your LAS file: Drag and drop your file into the upload area or click to browse your files
  2. View data in table format: Examine the numerical values for each curve at different depths
  3. Switch to chart view: Visualise your log data as interactive curves
  4. Customise your visualisation: Select which curves to display, adjust the depth range, and change the chart orientation
  5. Export your visualisation: Download the chart as an image for use in reports or presentations

Applications

Our LAS file visualiser is valuable for professionals across various geoscience disciplines:

Mining & Exploration

  • Mineral deposit characterisation
  • Stratigraphic correlation
  • Geotechnical assessment
  • Groundwater monitoring

Geotechnical Engineering

  • Site investigation
  • Foundation design
  • Soil and rock characterisation
  • Subsurface condition assessment

Technical Notes

Our tool supports LAS files conforming to the standard LAS format (Versions 2.0 and 3.0). The visualiser automatically recognises common curve mnemonics and applies appropriate units and descriptions. For optimal performance, we recommend using LAS files under 10MB in size, though larger files can still be processed with potentially longer loading times.

Supported Features:

  • Standard LAS file sections (~V, ~W, ~C, ~P, ~A)
  • Automatic curve recognition and categorisation
  • Null value handling
  • Adjustable data resolution for performance optimisation
  • Vertical and horisontal chart orientations
