5D Interpolation

Enhancing Seismic Data Regularity, Coherency, and Noise Attenuation

Seismic Data Regularization and Interpolation

5D Interpolation allows you to interpolate small gaps in seismic surveys and/or approximate geometrically regular output from regular or irregular input. The process helps enhance reflector coherency and attenuate random noise, but it may smear through find details, so it should be tested before we apply this process.

5D Interpolation Algorithms

MWNI (Minimum Weighted Norm Interpolation)

POCS (Projection onto Convex Sets)

Applications of 5D Interpolation in Seismic Processing

Potential applications of this tool include:

  • Migration noise reduction
  • Acquisition footprint attenuation
  • Azimuthal velocity analysis for imaging improvements or fracture detection
  • Near-surface reflection continuity improvement
  • Preparation for AVO analysis or subsequent multiple suppression
  • Potential for future survey acquisition cost reductions

Data Fidelity and Application Considerations

The process helps enhance reflector coherency and attenuate random noise, but it may smear fine details, so it should be tested before we apply this process.
