Data Analysis

Fast random access to multidimensional data combined with synchronisation between views and data layering control results in powerful data analysis capability. Processed seismic volumes stored in a project datastore along with reservoir simulation output can be overlayed and linked back to the original pre-stack data. Sequential in-lines or gathers can be superimposed into an optical stack for quickly spotting trends through the data. Synchronised panning and zooming across views makes it easy for users to interpret trends and understand attribute relationships.

INTViewer includes horizon picking capability, providing snap to minimum or maximum amplitudes, and zero-crossings. Users can use INTViewer to pick horizons on gathers, inlines, cross-lines or any other key in the data. Horizons can also be loaded from INTViewer XML based format or through an OpenSpirit enabled data store. A graph of the horizon amplitudes can be optionally displayed above the seismic traces for AVO type of attribute analysis.

Interactive cross-plot functionality helps determine relationships between two variables from any loaded datasets. Cross-plot data points can be highlighted from selected areas in the data source windows. Conversely, cross-plot source data can be identified by selecting areas of the cross-plot display.

Histograms can be created from any user defined data area within a window. Attribute bin sizes can be determined by the user interactively and values at any cursor positon shown at the bottom of the display.

3D Visualisation

3D view of 3D seismic and attribute volume

INTViewer includes an integrated 3D viewer capable of displaying inlines, xlines, time slices, arbitrary traverses and probes from one or multiple data volumes. The display of horizon data is also supported. Synchronisation of events and attributes can be enabled between 2D and 3D views. Multidimensional dataset, including 4D and 5D dataset can also be viewed using the 3D viewer. Thanks to its unique disk-based random data access architecture, there is almost no limit to the size of dataset that can be displayed using the 3D viewer.

Extensible Architecture

An advanced plugin architecture provides for enhancement of INTViewer functionality, offering interfaces for custom data sources, custom data views, and integration of processing algorithms. By utilising plugins, customers can easily and quickly add functionality to suit specific requirements. The standard package includes a Calculator plugin that allows users to input algebraic expressions and mathematical functions to combine one or more data input streams into a standard view.

Layered and Synchronised Views

INTViewer supports the integrated display of heterogeneous data including seismic and velocity, layer based reservoir models, horizons and maps. Views can be layered with no restrictions, so that it is possible to display seismic traces on top of a model or build an optical stack made of several adjacent gathers with transparency.

Complete control over layering is provided, including stacking order, visibility and transparency. Any attribute of a layer can be synchronised with attributes of another layer, including scale, plot attributes, cursor location, etc. Views can communicate with each other so that, for example, selecting a trace of an inline section will display the corresponding cross-line and gather. Cursor location can be tracked across multiple views. Scrolling can also be synchronised across views.

Flexible Data Handling

INTViewer is designed to efficiently visualize very large multidimensional datasets. Both prestack and post-stack seismic traces can be accessed through any key in the data such as inline, cross-line, CDP, offset, realisation, etc. Easy navigation along any direction in the data is possible through menu shortcuts. A transpose utility is available for accessing 3D data as time slices for display as a map or in a 3D display.

INTViewer provides a flexible data interface with built-in support for common data formats such as SEGY and Seismic Unix. A simple XML descriptor is used to support the various versions of SEGY format, and can also be used to define proprietary formats. An indexing wizard allows users to build indexes for fast random trace access, and multiple SEGY files can be combined into one logical dataset. An optional OpenSpirit interface provides access to OpenWorks™ or GeoFrame® datastores..

Web-enabled

INTViewer may be run as a traditional application or accessed as an applet through any Java enabled web-browser. Users can analyse data and collaborate remotely through a company internal web site or across the Internet. Analysis sessions may be saved at any time, with links to saved sessions identified by representative screenshots. A user only needs to select the appropriate screenshot to restore a session, at which time the Viewer automatically downloads itself and restores all views exactly as they were saved.
