Oasis montaj by Seequent – Industry-Standard Geophysical Data Processing & Interpretation Software
Oasis montaj is the leading desktop software for geoscientists to process, visualise, model and interpret large multi-method geophysical datasets. Seamlessly handle magnetic, gravity, electromagnetic, resistivity and radiometric data from acquisition through to final interpretation in a single, high-performance project environment.
Built for mining, energy, environmental and exploration teams, Oasis montaj delivers powerful QA/QC, advanced gridding, filtering, mapping, 2D/3D modelling and geological integration. Manage massive datasets with the Geosoft database, maintain full data traceability, and connect directly with Leapfrog and other Seequent tools for true multidisciplinary workflows.
Trusted worldwide for over 30 years, Oasis montaj turns complex geophysical data into clear, defensible subsurface insights — faster and with greater confidence…

What’s New in Oasis montaj 2026.1 – Highlights & New Functions
Oasis montaj 2026.1 delivers meaningful workflow improvements and powerful upgrades to the Radiometric Processing Extension (developed in partnership with Medusa Radiometrics).
Smarter Workflow Updates
- Reorder and update multiple database channels in one step – Save significant time when organising large geophysical databases. No more repetitive individual channel edits.
- Zoom directly to the cursor location on maps – Navigate large survey areas more naturally and precisely. Simply point and zoom without constant panning or guessing the centre of interest.
These seemingly small changes remove friction from daily tasks and make working with complex projects feel noticeably smoother.
Enhanced Radiometric Processing Extension The modern Radiometric Processing Extension continues to evolve, giving geoscientists clearer insight and better control over high-channel gamma-ray spectrometry data (fully supporting 512, 1024, 2048, 4096+ channel systems):
- See exactly where smoothing is applied and measure how much the spectra have changed
- Choose NASVD filter settings using eigenvalue and eigenvector plots for more informed, defensible noise reduction decisions
- Align measured radiometric energy peaks to standard windows with improved accuracy
- Compare multiple radiometric spectra side-by-side in one view — even when datasets have different channel counts
These enhancements make radiometric workflows more transparent, better aligned with IAEA recommended practices, and easier to quality-control. The result is higher-confidence potassium, thorium, and uranium maps for geological mapping, alteration studies, and environmental assessments.
