INTViewer Features and Functions

General

INTViewer is a small footprint cross-platform intuitive seismic data viewer and analysis tool providing swift access to large multi-dimensional or multi-volume data sets.

Hardware requirements are minimal, one gigabytes of memory with Java installed and enough disk space to hold the user data sets. The same installer can be used on Windows, Linux, Solaris, MacOS Systems, both 32 and 64 bit.

Data Preparation Utilities:

  1. Data Indexing (Seismic Indexer), can be executed:
    1. As a tool from within INTViewer
    2. Script with a GUI
    3. Command line with user defined parameters.
    4. No limit in data size or dimensions.
    5. Does not create a copy of the data.
      Some formats have built in referencing and do not require indexing, such
      Formats are SEP, JavaSeis and others.
  2. Seismic Transposing (SeismicTransposer) for viewing time/depth slices of data sets too large to be held in memory. Can be executed:
    1. As a tool from within INTViewer
    2. Script with a GUI
    3. Command line with user-defined parameters

Data Formats Supported:

  • Seismic

    2. P1-90 acquisition geometry
    3. Lat-Long or XY UTM
  • Pointset data
    • Points are specified using three coordinates and any number of attributes. These "points" can be displayed as layers in XSectional, Map View, and 3D windows. The visibility of the points can be controlled based on its attribute range. The point attributes can be edited and saved.
    1. Internal XML format
  • Well data
    • Wells can be displayed in their X & Y coordinates in Map Views and 3D Views. Wells trajectories are projected onto XSectional Seismic data color coded to indicate in plane and out-of-plane. Individual log curves may be displayed in traditional well track display. A generalized ascii reader is available for associated deviation files.
    1. LAS, versions 2.0 and 3.0

Extensibility:

INTViewer is designed as a NetBeans platform. Using NetBeans Rich Client Platform and IDE, users can easily create and deploy their own plugins. Plugins can be used to extend the functionality of the viewer including new data types, new windows or graphics, proprietary algorithms, complete workflows, etc. Plugins are managed through the Update Center which let users download, install, remove and update plugins. Common plugin types are:

  1. Data Plugins enables easy addition of readers/writers for any data type or new data types can be created for custom layers.
  2. Processing Plugins, also known as pipeline plugs, allows the insertion of on-the-fly processing for seismic display just before visualization. Such existing plugs are the phase rotation, band-pass filter and anglefield calculation.
  3. Analysis plugins for simple tasks such as signal to noise analysis.
  4. Workflow Plugins, allow the integration of complete workflows into the viewer including step by step instructions. Examples of customer workflows include velocity scanning and QC of navigation data.

INTViewer provides a rich API for building plugins. Please see the INTViewer Developer Wiki for more information.


Portability:

INTViewer is written in Java, therefore it is independent of platform. As long as a Java JVM exists for a hardware type, the INTViewer will execute on that platform. It executes for both the 32bit and 64bit versions of Java and Java3D. The INTViewer has a small footprint: from a memory requirement of less than 1GB, it can handle data sets of nearly unlimited size. If memory greater than 2GB exists, the startup scripts may be user modified to take advantage of larger memory

    Synchronization:
    All windows are communicate such that a scroll bar movement in one window causes all scroll bars to move synchronously. The cursor will be at the same location in all windows, movement in one window produces an identical movement in all other windows. Variables and parameters can be shared between windows and layers, such that changing the parameters in one window, changes all windows.

    Broadcasting:
    Within any window a point may be selected by a mouse click and then its coordinates (Keys) can be broadcast to all other windows, both 2D and 3D, for immediate update.

    Layering:
    Within any window, multiple Seismic layers can be overlaid. Opacity control is available on all layers so that underneath layers may be seen simultaneously. The seismic layers can be of diverse types; velocity, amplitude or attribute data. Operations on layers are:

    1. Independent normalization (gain)
    2. Both horizontal and vertical curtains are available when two XSections are overlaid within a single window. One data set visible on each side of the cursor position.
    3. Automatic rotation between all layers with speed (time) control.
    4. Opacity control.
    5. Color control
    6. Display Types.
    7. Layer ordering
    8. Layer visibility
    9. Layer deletion

    Drag and Drop Data Movement:
    Data can be input to a window by drag and drop from a data browsing dialog box that displays the data repository. Data can also be moved from window to window by a simple drag and drop procedure. This data drag and drop feature spans both 2D and 3D Displays.

    Window scaling:
    The active window type is sensed by the scaling dialog and appropriate scaling parameters are presented for the window type. The data set can be scaled to completely fit within the window by the "View All" option.

    Window Annotation:
    Complete annotation is available for the axes, titles, and labels. Labels update automatically when window changes. XSections can be labeled with any trace header value. Font type and size can be specified.

    Window Zoom:
    Zoom can be performed in steps of 2 or by rubber-band selection of an area. The window can be returned to its original status by a zoom-reset.

    Window Placement:
    Individual windows can be arranged manually, or by using the Tile All, Tile Vertically, Tile Horizontally or Cascade options. Windows may be undocked (moved off of the main window) and docked.

    Session Saving and Restoration:
    At any time, the current windows, data set information and parameters can be saved to a configuration file. This session file can be used at any time to restore the INTViewer to the identical conditions as when the session was saved.

    Tools:

    1. Histogram: gives graphical sample value distribution for data selected by user.
    2. Cross-plot: cross-plots any two matching layers and displays the cross-plot results in a new scalable window. The cross-plot can be linked to any layer by a "drag and drop" method. This link allows data within a user defined polygon to be color highlighted on the linked layers or conversely, data selected in a user defined polygon on the layer, will be displayed in the cross-plot window. Features include:
      1. Ability to view a cross-plot between two seismic data sets (or subsets thereof) or two attributes of the same horizon.
      2. Cross-plot points can have single color, be colored based on time/depth or based on a third dataset.
      3. Ability to select and save a subset of cross-plot points and highlight those points in a seismic display.
      4. Ability to select an area on the seismic display and highlight the corresponding points in the cross-plot view.
      5. Ability to animate (blink) the points on the Cross-plot which represents the internal points of a polygon on the Seismic Data.
    3. Snapshot: put an image of the active window on the system clipboard, so that it may be pasted into other documents.
    4. Movie tool: captures a user specified number of frames, one per window change (increment) and enables the playback of these frames at a specified speed.
    5. Data Browsing: a dialog box detached from the main window and shows the INTViewer compatible files within the directory structure specified by a user defined environmental variable.
    6. Spectrum Analysis: provides a spectrum analysis of one or more rectangular selection in your data. Options include Amplitude Spectrum, Phase (wrapped or unwrapped), Power or Db Spectrum.
    7. Odometer: at the bottom of the screen continuously gives the Key coordinates (such as InLine and Xline) in addition to the data value at the cursor position.
    8. Calculator: available in both XSection and Map view modes. Performs on-the-fly user defined computations on multiple data input to visualize the resulting data set.
    9. FK Analysis: support for FK analysis of a complete seismic dataset or of a selected subset.

    Optional Plugins:
    Many optional and free plugins can be downloaded from INTViewer update center. These include plugins for signal to noise analysis, Butterworth filter, angle field calculation, spherical divergence, support for reading SMT seismic data format and more.

    Hardcopy:
    INTViewer can save print to a printer with a variety of configuration and print preview options, or save views as "PDF" files. Views can also be exported as CGM files.

    Shortcut Windows Shortcut Windows with contain the most commonly used properties parameters has been supplied at the left for ease of use. Shortcut windows exists for the most common types of windows and layers.
