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.

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.

SeisRoX Basic
SeisRoX Basic is a flexible, efficient and easy-to-use seismic modelling software which rapidly simulates the seismic response of geological reservoir models including the effects of a complex 3D overburden and source-receiver illumination/resolution effects.
SeisRoX Basic focuses on a local scale and contains three types of workflows:
SeisRoX Pro
SeisRoX Pro includes all the Basic functionality, and in addition it contains a full-field PSDM simulation workflow. With the Pro version, larger scale modelling is done by utilizing space-varying Point Spread Functions. Detailed studies of the space-varying PSF's can be done with the new PSF focusing map.
SeisRoX Pro also includes Rock Physics transformations to describe and calculate the relationship between geological properties and the effective (average) elastic and seismic properties to be used in the modelling. With the Rock Physics functionality the seismic response of rock property changes can be studied.

NORSAR-3D 2016
NORSAR-3D 2016 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.
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.
NORSAR-3D Basic is released on both Windows and Linux while Pro and Expert are currently available on Linux.
NORSAR-3D 2016 is backward compatible with older versions of NORSAR-3D project data.
NORSAR-3D Basic is designed to perform kinematic illumination studies of any type of acquisition survey. Model elements, like surfaces and attributes can be imported or defined and user-friendly model builders can be used to set up model geometries and elastic properties. The software contains the modelling tools, Illumination Rays and Illumination Maps and runs on Linux and Windows.
Import
Allows the user to build a model from externally available model elements, interfaces, property grids and cubes, point sets and polylines as well as surveys like P1/90 and SPS surveys can be imported.
Model Builder
In many cases, simple models can be used for initial illumination studies and first survey planning steps. The basic version supports therefore to build models, e.g. if there only is a property cube, a single target horizon, or a stack of horizontal interfaces that are not interacting in a way that needs any specific consideration, preprocessing or modification
Single Block Model Builder
Here, only one property cube is used. The property cube can either be imported or generated by simple layer cake models.
Single Reflector Model Builder
In order to generate Illumination maps a target reflector is required. The model properties above and below the target reflector can be set by either selecting property cubes or set to constant.
Grid Layer Cake Model Builder
The grid layer cake models can contain various surfaces which separate the layers. The property values are either constant or gradients.
Illumination Rays
For a systematic and comprehensive analysis of ray propagation, the illumination rays workflows should be used. Here, many target points can be analyzed, and all reflection angles and azimuths are taken into account. The results for each target point are shown in a survey- and a target-domain rose diagram.
Illumination Maps
Illumination maps show how well a target horizon is illuminated by a survey. The basic map is the hit map, which displays for a specific survey how many rays from shots to receivers reflect on the different parts of the horizon. Shadow zones clearly stand out on hit maps
NORSAR-3D Pro 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 of any type of acquisition geometries. Major new features in this version are the S-wave anisotropy in transversely isotropic media (VTI, HTI and TTI). Furthermore, this new version contains significant improvements on the survey import (SPS) and the wavefront tracer with respect to memory handling and performance.
