NORSAR-3D 2017 features a novel NORSAR-3D Pro version which is now available on both operation systems Windows and Linux. NORSAR-3D Pro 2017 includes the Basic version and in addition a comprehensive set of tools and workflows to build complex models and do illumination studies and survey planning for any type of acquisition geometries. Major new features in this version are: A complete new interactive 3D Model Builder for creating from simple to complex 3D models, a redesigned intelligent Ray Tracer workflow to study wave propagation in detail, and improved workflows to generate Illumination Maps and Synthetic Seismograms. In addition an innovative batch system is included for distributed parallel processing of large simulation jobs on a cluster of Windows  or Linux machines.

The NORSAR-3D Pro version is the upgrade version for existing customers.


NORSAR-3D Pro includes the Basic version, and in addition it contains a comprehensive set of tools and workflows to build complex models and to do illumination studies and survey planning for any type of acquisition geometries. NORSAR-3D Pro 2017 is backwards compatible with older versions of NORSAR-3D project data, and it is released on both Windows and Linux.

Model Builder - NEW

Now a novel interactive 3D model builder is available. It allows to build complex 3D models, and it displays the model elements in the 3D viewer with access to all other project elements.

The model builder includes:

Use interfaces of any shape, including multi-z-valued interfaces.
Intersect and combine interfaces.
Build blocks (volumes) automatically as well as interactively with extensive graphical support.
Set P- and S-wave velocities, densities, Q-factors, and Thomsen parameters as constants, grids, or cubes independently in each block.
Use VTI anisotropy as well as axis of symmetry orthogonal to the layering.
Allow gaps and undefined areas in the models.

Interactive Tracer workflow - NEW

The re-designed interactive tracer can be used to analyze the ray tracing results in more details for one selected shot location. The propagated wavefronts can be plotted as well as the corresponding ray attributes such as traveltimes and amplitudes.

Seismogram Generation workflow - NEW

The Seismogram generation workflow generates synthetic pre-stack seismic data for a user-selected part of the wavefield based on dynamic ray tracing. Both isotropic and anisotropic models are allowed, and in these structural models any combination of reflected, transmitted and converted P- and S-waves can be propagated. 

Simulated migration amplitude workflow - NEW

Simulated Migration Amplitude (SMA) maps show estimates of how the amplitude will vary along the target reflector after pre-stack depth migration. This workflow allows you to investigate effects on illumination including attenuation effects in the overburden as well as varying reflectivity at the target. The Simulated Migration Amplitude workflow does not only compute the SMA maps; in addition it computes all the attribute maps that are also made in the Illumination Map Workflows.

Distributed parallel processing – NEW

When running a workflow, it is distributed over all available CPU's and cores on the local  computer. This improves computer speed significantly. In addition, it is also possible to distribute these jobs to other computers available in the network. The execution time of the workflow will decrease dramatically.

In addition, minor bug fixes and stability improvements.
