Table 2 Processing sequence applied to 3-D seismic data volume in Groß Schönebeck
Workflow segment | Processing tool |
|---|---|
Field processing | Source-/receiver-/CMP-geometry |
Main processing | Minimum-phase transformation Elimination of bad traces Airwave suppression |
Data preparation and correction | Static correction (short refraction lines, first-break picks) Spherical divergence correction Surface-consistent amplitude correction Deconvolution (predictive and adaptive) Residual static correction Noise-suppression (time-slice analysis) |
Stacking—option 1 | Common Mid-Point processing: velocity analyses + NMO correction + stacking |
Stacking—option 2 | Common Reflection Surface processing: CRS analysis + stacking |
Migration and depth model building | Post-stack time migration f-xy deconvolution Zero-phase transformation Time-depth conversion |
