Pseudo 3D Seismic

 Generating 3D Seismic Cube from Sparsely Distributed 2D Seismic Lines

Data input:

  • 2D Seismic Lines (Stack-SEGY)
  • Horizons Interpretation

General Process:

  • 2D Data conditioning: Amplitude and Frequency Balancing, Miss-Tie Alignment,  Enhancement, Sampling rate equalization, etc.  
  • Generating target 3D Grids: inline-xline numbers, inline-xline increments, azimuth, orientation.
  • Perform Amplitude prediction via Geostatistical  Interpolation guided by horizon
  • Demigration-Remigration 
  • Finetuning 

Data Output:

  • 3D Seismic Cube in SEGY Format

Quality Control:

  • 3D Seismic Cube-2D Seismic Line Tie
  • Time Slice Integrity

 


Sparsely distributed 2D Seismic Lines are used in the example. Variation of geological settings are shown in the seismic section (Data: F3 Netherlands-Open Data)
