Simplified handling for larger and more complex seismic surveys

 

Echos™

New Features Why it Matters
  • Vibroseis Slip-Sweep Harmonic Noise Attenuation
    • Enable the attenuation of harmonics in the correlation sweep and in the seismic data before cross-correlation.
  • More effective attenuation of noise from the harmonics in the seismic record output after cross-correlation.​
  • While designed to improve the handling of modern slip-sweep Vibroseis recording, the technique is also applicable to legacy Vibroseis recording.

  • Radial Trace Decomposition/Reconstruction (RADIALT)
    • A new module enabling forward and inverse radial trace transformation of seismic records. The radial trace transform domain is suitable for attenuating source or receiver borne coherent noise, such as ground roll in land and guided waves in marine acquisition.
  • This is a significant addition to the signal enhancement and noise attenuation capabilities available to Echos customers.
  • The radial trace domain separates various portions of the seismic wavefield in the transform domain, enabling users to develop workflows for attenuating portions of the seismic wavefield that are considered to be noise, minimizing the impact on the seismic signal of interest.

 
  • Residual Statics – Conjugant Gradient Solver
    • Enhancement to the  Echos RESSTAT module; includes a new prestack time-pick based conjugant gradient solver for surface consistent residual statics, and a new trim statics solver for non-surface consistent statics. (Complement the residual statics solvers based on stack-power methods that were introduced in Paradigm 18.
  • More effective utilization of compute resources
  • Improved support for modern seismic survey geometries
  • 3D Poststack Survey Interpolation
    • A new module for interpolating a 3D poststack volume to a new survey binning geometry, using 5D data modeling and reconstruction technology.
    • Leverages Echos' innovative use of the radon transform in seismic wavefield decomposition and reconstruction.
  • Modern seismic wavefield interpolation technology simplifies 3D poststack survey re-binning. 
  • Improved workflows for merging multiple 3D surveys.
  • Improved handing of aliasing in the spatial transformation domain.

GeoDepth™

New Features Why it Matters
  • Tomography Multiple Parameter mode
    • Enables the user to simultaneously run multiple tomography jobs using different parameter setups.
    • Assessment and comparison of results through the 3D Canvas and pencil repository visualization tools, and using pre-defined statistical measures.
    • Also available for Kirchhoff time/depth migration and Pre-stack Picker for optimal modeling and imaging.
    • Can be used to provide statistics for resource management.
    • Supports different HPC configurations at the user’s convenience.
  • Enhanced productivity through automation of the parameter scaling process for the tomography workflow.
  • Improves confidence in tomography results by addressing the non-uniqueness nature of the analysis and the fact that each step of the workflow may have multiple possible outputs.
  • Easy visualization of multiple results.
  • Helps in assessing model uncertainty.
  • Tomography Varying Update Grid
    • The vertical size of the tomography update grid can now vary with depth.
    • Defined via a depth-value table or computed internally using the Fresnel zone assumption for resolution limits.
  • A leap in both quality and productivity:
    • Automation of varying update grid scaling by maximizing resolution per depth (according to the model and data) enhances user productivity. 
    • Enables high shallow modeling resolution while maintaining manageable run times. 

 
  • Multi 2D line framework enhancements
    • Multi 2D section manipulation with multiple options; new and improved UI.
    • Enhancements to the multi 2D tomography workflow.
  • Improved flexibility of the multi 2D line framework – easy to handle and process multi 2D data.
  • Improved output quality of multi 2D line modelling and imaging.

  • Seismic operation toolset enhancements
    • Improved processing of 3D gathers through additional filters (Radon, F-K) and operations (angle-to-offset, RNMO correction).
    • Enhancements for PMLI (QSI)
  • Optimized input for 3D gather analyses (AVAz, VVAz)
  • Richer toolset provides additional gather processing options for imaging and QSI, increasing user flexibility.
  • Kirchhoff Enhancements
    • OVT binning application
      • An interactive application to set up 3D Kirchhoff OVT gather output binning, including visualization of output fold vs input data distribution.
      • Option for extended binning - reconstructs data-deprived bins with sparse information using neighbouring traces.
      • Option to add Voronoi weights - enhances amplitudes around data-deprived regions.
    • Star output
      • Output multiple azimuthal sectors by given central azimuths and apertures.
  • Easy interactive QC and visualization, enabling user to better calibrate gather output binning according to the input acquisition distribution, for improved image and gather quality.
  • User’s ability to focus on targeted regions results in optimal inputs for pre-stack analysis (such as fracture characterization and other QSI analyses).
  • Extended binning and Voronoi weight options further enhance output quality.

EarthStudy 360™

New Features Why it Matters
  • Converted wave mode in EarthStudy 360
    • Provides P-S (pressure-converted to shear) EarthStudy 360 reflection and directional gathers and P-S images, using radial components achieved by multi component recording technology.
  • Provides complementary information to standard P-P images and gathers in the subsurface model, increasing user knowledge of the subsurface.
  • Especially important for imaging areas below gas clouds and salt bodies where P-S information is richer.
  • Dramatically reduced I/O initialization time
  • Significant improvement in productivity, reducing the entire migration runtime by 10-20%.
  • Reduces by 50% idle cluster time for initial I/O stage.
  • Particularly important for cloud runs.


Infrastructure

New Features Why it Matters
  • Faster saving of seismic, traveltime and tomography data (e.g. from Echos and EarthStudy 360) 
  • Improved performance
