Subsurface Explorer

Open Source, Minimalistic, Modern 3D Geoscience Viewer

Current Features

  • Load and display 2D seismic sections (SEG-Y)
  • Load, display and navigate in 3D seismic cubes (SEG-Y) — inline, crossline and time/depth slices
    • Compute 3D seismic cube attributes (envelope and similarity)
  • Load, display interpreted horizons (ZMAP+)
    • Pick (create and edit) horizons
  • Load and display well trajectories (CSV)
    • Load and display well logs along the wellbore (LAS)
    • Visualise cones of uncertainty
  • Convert objects between time and depth domains, and between meters and feet

Note: The light SEG-Y file comes from dGB Earth Sciences. We thank dGB Earth Sciences for making the data available as an OpendTect project via their TerraNubis portal (terranubis.com). All other files — seismic, well trajectories, and well logs — come from NLOG, the Dutch national oil and gas portal. The NLOG data are provided “as is”. Neither NLOG nor TNO accepts any liability for the accuracy, completeness or fitness for purpose of the data, nor for any consequences arising from their use. The full NLOG disclaimer can be found at nlog.nl/seismische-data. Neither NLOG, TNO nor the Dutch government endorses Subsurface Explorer.

About and Contact

Subsurface Explorer is developed by an AI-assisted (to be honest) solo developer, on their free time. Their goal isn’t to compete with the already established names like Petrel (commercial) or OpenDTect (free and open source). Subsurface Explorer is an humble side project, focused on essential functionalities and a clean modern interface.
