Through constant interaction with our software and services clients, we aim to continue to deliver the best, most efficient modelling tools available, following the extraordinary advances we see in the industry.

NORSAR Software Suite 2024 (2024.0.0 July 2, 2024)

NORSAR Software Suite 2024 is a new release featuring new functionality, improvements and bug fixes.

General functions

Colour scale:

Scientific colour scales are available in 3D viewer

Well log import:

Well path can be specified by inclination and azimuth down along the well

Workflow queue manager:

More workflow types can be queued, including Kirchhoff modelling and migration workflows.

Modelling project editor:

Added a tab for setting preferred display unit for selected attributes

Seismogram generation:

Offset is now included in the SEG-Y file trace header.

 NORSAR-3D

Make elements:

Property imports as SEG-Y: Improved explanation of how to change number of traces, etc.

Build models:

In Single reflector model builder, corrected wrong display when P/S-ratio was specified.

In General model builder, corrected holes in properties made by interpolation between horizons.

In General model builder, corrected the generation of properties by analytic functions when spatial units are not km. 

Fixed problem with a crash in general model builder on interface operations

Survey:

New survey type: Orthogonal survey.

Kirchhoff migration workflow: 

Can now reuse the Greens’ function from the corresponding Kirchhoff modelling workflow.

Illumination Rays (IRAY):

The results can be limited by areal filters in the shot and receiver domains.

Fixed bug that exclusion filters were ignored

Fixed bug that Shot-receiver azimuth filters, incident reflection angle filters, and departing reflection angle filters were ignored

The Help is improved.

In anisotropic models, now rays for all incident angles are computed; used to be just a half-circle.

Fix crash in survey generation for flower plot generation 

For survey dependent workflows, added warning about long compute time for large surveys

New Fast track utilities workflow: 

Workflow to estimate Minimum Bin Size / Maximum frequency to avoid aliasing.

NORSAR-2D

General ray code: 

More detailed explanation in the Help.

SeisRoX

Full-field workflow:

Fixed error in Greens Function Generation for SeisRoX Full-field workflows, causing illumination vectors to be wrong. This bug was introduced in version 2023.1

MDesign

Sensor file import

Now also handles files with no noise floor information.

Detectability workflow:

Corner frequency is no longer needed as input.

Corrected algorithm for magnitude estimation.

Location uncertainty workflow:

Corrected algorithm for magnitude estimation.

DAS Illumination workflow:

From the input survey, only the receivers are used.

Fixed error in backazimuth computations

Amplitude statistics (min,max,average)  are provided.

Added option to show the absolute number of receivers in addition to percentage of all receivers

In addition, several stability fixes and improvements.
