Processing & Imaging

With this release, time and depth based processing workflows share velocity analysis tools, presenting users with a consistent user experience and toolset, whether they are working in the time or depth domain.  Specific enhancements include:


New Feature Customer Value
Enhancements to Echos Reverse Time Migration (RTM)
  • Variable density for both isotropic and TTI models in RTM
  • A new option to migrate poststack data.
  • Delivers a more accurate representation of the effects of wave propagation in the subsurface
  • Adds flexibility in the application of RTM imaging
  • Orientation analysis for X and Y components in data acquisition
  • Analysis of S-wave splitting, finding fast and slow directions
  • Correction of the effects of S-wave splitting in a layer stripping manner
  • Enhanced multi-component data analysis, QC and processing
  • A new module (RNA) for shearlet-based attenuation of ambient noise in seismic data
  • Amplitude-preserving random noise suppression
  • A new module for receiver motion correction for towed cable marine acquisition
  • Improved stacking response for marine data


New Feature Customer Value
Enriched velocity model updating (tomography)
Before and after time-preserving tomography in the Eagleford Shale
Before and after time-preserving tomography in the Eagleford Shale
  • Re-depthing capability enables users to consistently tie the depth/velocity model to wells in a single run
  • information/geological constraints while remaining loyal to the structure and seismic in a flexible way.
  • An additional constraint to tomography to enhance the accuracy of produced subsurface models.
  • Full workflow for Offset Vector Tile (OVT) gathers (prestack data)
  • Enables sectorization of OVT gathers, imported or created using the Paradigm Kirchhoff migration, which can then be used as input to 3D Tomography or AVAZ/VVAZ
  • Model-centric velocity determination using GeoDepth-SKUA integration:  Velocity volumes, geological formation volumes, and dip/azimuth volumes created in SKUA can be used in Illumination, grid tomography and migrations, and RTM modeling workflows
  • Enables GeoDepth users to use SKUA structural and stratigraphic model building capabilities in the depth imaging workflow. Particularly important in geological regimes defined by faults, salt bodies, unconformities, etc.
  • Geological formation volume and dip/ azimuth can guide and control grid tomography updates for complex models.
  • Faults and other discontinuities are honored properly in the velocity model to avoid imaging artifacts
  • Batch mode for CVS in Velocity Navigator
Batch mode for CVS in Velocity Navigator
  • An effective QC tool for residual and velocity function picking

EarthStudy 360

New Feature Customer Value
  • Significant improvements in run time (app. X5) enable EarthStudy 360/CRAM to be run on large datasets
  • Faster results while maintaining high imaging quality.
  • Dramatic reduction in migration parameters and easier setup of runs on clusters
  • Enables users to run the migration independently with less help from Paradigm experts (advanced parameters are still available for expert users)
