Understand the relationship between datasets

Crossplotting

Expanding the interpreter's portfolio.

The Paradigm® easy-to-use Crossplot tool provides sophisticated analysis of relationships between datasets.

Paradigm Crossplot
 

Paradigm Crossplot may be used in a broad range of workflows:

  • Perform multi-purpose data analysis and integration
  • Analyze the differences between multiple angle stacks and detect fluid anomalies
  • Analyze the differences between vintage datasets
  • Compare data processed using different velocity models
  • Analyze the effect of the velocity on seismic data

Crossplot may also be used to calibrate between seismic and well data for quantitative interpretation.

Other projects where Paradigm Crossplot can be applied include:

  • Pore pressure prediction
  • Seismic attribute analysis
  • Formation evaluation
  • Time-depth analysis
  • Prospect identification
  • Geologic targeting

Paradigm software supports crossplotting on different types of data, such as seismic-driven data volumes, horizons and interpretation data, well data and vertical functions. Some applications also support the integration of different types of data in the crossplot space, such as crossplotting synthetic data (wells) and seismic data.
 

Crossplot benefits

  • Interactive crossplotting integration into the 3D environment (SeisEarth® and VoxelGeo®) expands the interpreter’s portfolio with tools for incorporating multiple attributes into the interpretation work process.
  • Real-time updates of crossplot information enhance interpretation efficiency and productivity.
  • 3D viewing of AVO geobodies through dynamic links between AVO crossplot and VoxelGeo/SeisEarth 3D Canvas provides an immediate, holistic understanding of 3D AVO fluid anomalies in the reservoir.
  • Integration of numerous data types (well, seismic, horizons) and disciplines (petrophysics, geophysics, geology) facilitates the interpretation process.
  • Unique capabilities for interactive crossplotting open a new range of possibilities for multi-attribute seismic data interpretation in a 3D visualization environment.
  • Crossplot results can be visualized in color inside the 3D volume, enabling the identification of regions with specific multi-dimensional characteristics within seconds.
  • Interactive capabilities for color coding the crossplot space enable data classification, for more detailed reservoir characterization. 


Crossplot features

  • Proprietary angle crossplot, for better separation of AVO anomalies from background trends
  • Ability to easily compute, draw and edit a crossplot relationship between different data types, and save it for later use
  • Horizon and well marker-constrained crossplotting for target analysis
  • Application of crossplot relationships to generate new attribute files, maps, logs, etc.
  • Seismic and well data crossplot in the same space
  • Combined data analysis and 3D co-visualization for cluster analysis and geobody detection
  • Simultaneous visualization of input data and crossplot detections with the Paradigm opacity engine (VoxelGeo and SeisEarth 3D Canvas)
  • Customizable color coding schemes - rectangular grid, polar grid (useful in AVO analysis), distance from a curve (useful in seismic reservoir characterization) - that may be used in a variety of workflows
  • Back projection of data and colors from crossplot space to data space, enabling 3D geobody detection and other workflows
  • Direct links from the AVO window to VoxelGeo for 3D viewing of geobodies as well as property distribution in the reservoir
