NORSAR-2D Release Notes

  • NORSAR-2D 5.3.1 (July 20, 2015)

    Version 5.3.1 is a bugfix release.

    Depth Mapper

    • Fixed bug when storing SMIF file and undefined values

    Model Builder

    • More robust SMIF storing

    Tracers

    • Fixed bug in Image Ray Tracer due to large number of ray codes
    • Allowing longer interface names in Common Shot Tracer

    Viewer

    • New reflectivity viewer
  • NORSAR-2D 5.3 (February 17, 2014)

    Version 5.3 introduces a new fully integrated 3D viewer with the ability to plot all data objects in a NORSAR project. The viewer is the first step to bring NORSAR-2D into the new NORSAR Seismic Modelling platform. This framework is already used for SeisRoX. Included in the release is also improved well handling of imported wells.

    FlexNet licensing 

    • Updated licensing to FlexNet 11.11 to handle alternate network interface names (e.g. em1)

    File Manager 

    • Upgraded to handle imported wells

    Viewer (NEW) 

    • Complete new module with advanced functionality to display all data objects in a NORSAR project, including NORSAR-2D section and models. In addition NORSAR-3D elements can be displayed such as IMAPs, FPLOTs and survey fold maps.
    • Option for interactive click & shoot of direct rays in 3D models

    Well Import

    • New functionality to upscale a well log
    • New option to compute TVD from MD
    • New option to derive VP and VS from slowness.

    Model Builder

    • Removed requirement for two-way-traveltime when loading a well
    • Assign property from wells now includes Vs and Density
    • Option to store model as a SMIF file for immediate use in NORSAR-3D

    Tracers

    • Fixed bug causing specification of "General Ray Code" to fail

    Seismogram Generator

    • Fixed "Include geometrical spreading" option such that when set to OFF also phase shift due to KMAH is off

    In addition minor bug fixes and improvements.

  • NORSAR-2D 5.2.1 (November 20, 2012)

    Version 5.2.1 is a compatibility update for the Nucleus version and an upgrade of the FlexNet licensing system.

    Nucleus

    • Fixed compatibility issue for Nucleus+ 

    Licensing

    • Upgraded to FlexNet 11.10
  • NORSAR-2D 5.2 (April 19, 2011)

    Version 5.2 is a major update of NORSAR-2D. Several new functionalities are added; new project definition, new digitizing tool, new SEG-Y property import/export and a new well import. In addition many size limitations are removed or reduced and bugs are fixed.

    Project definition

    • The project definition module is now in line with NORSAR-3D and SeisRoX. 

    Digitizing tool

    • New digitizing tool where scanned images or seismic on seg-y format can be used as background when digitizing horizons. The horizons can be used directly in the Model Builder.
    • In addition it can be used as an advanced SEG-Y displayer.

    Well import

    • New well import. Well track and well log can be imported.
    • Imports ascii column data. User defined interpretation of each column.
    • Predefined set ups can be stored.

    SEG-Y property import

    • New property import.
    • Imports property slices from cubes on SEG-Y format.

    SEG-Y property export

    • New property export.
    • Exports property grids on SEG-Y format. Property grids canbe made by gridding a model.

    Model Builder

    • Use the imported wells to define properties.
    • Increased number of allowed samples in horizons, property grids and SMIF files.
    • Improved messages when depth converting.

    Tracers

    • Reference interface is introduced in the VSP tracer. The same option is available in the Common Shot tracer and the NIP tracer. In NORSAR-3D, this is called projection interface.
    • Default search angles in the VSP tracer are now set to 0 –360 degrees.
    • Increased number of events in spikeogram plot, and number of shots and receivers.

    Seismogram Generator

    • Fixed bug when using diffraction events.
  • NORSAR-2D 5.1.6 (October 23, 2009)

    Version 5.1.6 includes 5.1 plus all patches.

    Common Shot Ray Tracer and VSP Ray Tracer
    Fixed a bug where no more diffraction events was written when reachingthe 2000 traceslimitation.
