NORSAR-3D

The new NORSAR-3D unveils a revolutionary new user interface for the NORSAR software. It makes the advanced and proven NORSAR-3D technology available in a completely new and simplified user experience.

NORSAR-3D is now part of the new NORSAR Software Suite framework.

The new NORSAR-3D is available in three different configurations: Basic, Pro and Expert. NORSAR-3D Basic is part of NORSAR-3D Pro and NORSAR-3D Pro is part of NORSAR-3D Expert. The NORSAR-3D Pro version is the upgrade version for existing customers. The new NORSAR-3D versions are backward compatible with older versions of NORSAR-3D project data.

From the new 2017.1 version of NORSAR Software Suite, all NORSAR-3D configurations are available on both Windows and Linux.

NORSAR-3D includes functionality that enables you to:

• Import data (grid, trimesh, cube, survey, 2.5D models from N2D)
• Generate 3D models
• Perform survey design and generation
• Perform ray modelling using the Wavefront Construction method
• Generate seismograms
• Generate illumination maps (IMAP),
• Export data (grid, cube, trimesh, seismogram, illumination maps, event attributes)

The NORSAR-3D package also includes batch processing, allowing models to be computed on multiple processors, greatly speeding up the turn around time.

Modelling Package

NORSAR-3D is the most advanced product on the market for seismic illumination studies and model-based survey evaluation and analysis. The package is also used on a full industrial scale for generation of traveltime maps for Prestack Depth Migration (PSDM).

NORSAR-3D uses the Open Ray Model representation to simplify model construction. The technology even allows seismic ray tracing in preliminary or incomplete depth models.

The wavefront construction technique, first developed and implemented at NORSAR, ensures that all calculated rays are consistent in the Open Ray Model. Model run times are reduced, without compromising results, by the efficient way in which NORSAR-3D calculates ray contributions for a large number of shot and receiver positions.
