The new NORSAR Software Suite is a common framework for NORSAR software and consists of NORSAR-3D and SeisRoX.
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.
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.
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.
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 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.
Improved SPS survey import
- Significant increase of performance importing SPS files for irregular surveys
- Significant less disc storage for imported SPS survey
- Keeping shot and receiver topology for imported SPS survey
- Introducing of S-wave anisotropy (TI anisotropy)
- Improved S-wave source
- Ray code improvements (transparency off)
Generation of seismograms for anisotropic models with S-wave ray codes.
All illumination maps are updated to handle S-waves in anisotropic media.
Introduction of standard deviation for all attribute maps
See under NORSAR-3D Basic.
NORSAR-3D Expert includes the Pro version and in addition unlimited batch processing capabilities and access to the project results to do in-depth analysis or tailored applications. Main new feature in this version is the introduction of the Kirchhoff Target migration workflow. Furthermore, this new version supports the extraction of S-wave anisotropy parameters from calculated event set.
Kirchhoff Target Modelling
New Kirchhoff Target migration workflow is introduced. It can be used to generate migrated sections from Kirchhoff prestack data.
