Release Notes for older versions of SeisRoX

  • SeisRoX 3.0.2 (June 25, 2015)

    Version 3.0.2 is a maintenance release with a focus on improving data import and upgrading the general rock physics framework: 

    CO2 is introduced as an additional fluid to be handled by rocks in order to estimate elastic properties of reservoir models. 

    Import of reservoir models from various sources is now facilitated by a newly established Petrel link that supports efficient data exchange between SeisRoX and Petrel. 

    Import of seismic or property cubes in SEG-Y format is significantly improved by a new import module that applies a new generation of the automatic topology analyser and allows for trace header review, selection, and scaling. 

    In addition, bug and stability fixes as well as minor improvements were done, such as adding maximum frequency information to generated wavelets in order to facilitate workflow setup and result analysis.

    Highlights of the new release are the ability to import a reservoir model as a cube and use it as a model element in a SeisRoX model, the Petrel plug-in for easy access of Petrel data, and the Time/Depth functionality is greatly extended. The SimPLI modelling is improved with several new options and the Illumination Vector generation is improved. In addition display options and the user interface is improved.

    SeisRoX cube models
    Extension of the SeisRoX reservoir model to include cubes as a model element.
    A SeisRoX model can consist of a set of cubes, a set of horizons or both cubes and horizons, all with property values attached to each node. This makes it easy to import and use external cubes in the SeisRoX modelling. 

    Petrel plug-in
    A new plugin for Petrel makes it possible to make a SeisRoX model directly from a Petrel simulation model or a Petrel geo model and write seismic data from the SeisRoX modelling back to Petrel for viewing and comparison.

    Cube Import
    New import function to import property cubes on SEG-Y format.

    Time/Depth functions
    Definition of time/depth functions is extended with an option to use a P-velocity cube as basis for the function.

    Fully integrated time domain
    All data elements and SeisRoX models can be defined and edited in both time and depth domain using a time/depth function transformation.

    Fully integrated time domain 3D viewer
    All elements can be plotted simultaneously in both the time viewer and depth viewer.

    Well handling
    More flexible import of well data and prediction of new logs based on depth trends.

    Handling of general surveys
    All NORSAR-3D surveys can now be sub-selected, plotted and used in the SeisRoX modelling. Sub-selection filtering based on X-offset and Y-offset is added.

    Illumination Vector improvements
    Tighter integration between NORSAR-3D and SeisRoX makes it easier and more flexible to take into account survey sub-selections and PSDM filters when generating the Illumination Vectors. In addition a new plot option to compare Illumination Vectors is added.

    New SimPLI modelling options
    New options and improvements in the SimPLI modelling are introduced to simulate various amplitude effects, including geometrical spreading and transmission. In addition, when selecting a pulse, a new option allows to simulate deconvolution by replacing the spectrum of the pulse by a white-spectrum.

    In addition stability fixes, minor improvements and miscellaneous bug fixes are included.
