Least-Squares Dip Angle 4D Migration for OBN and Towed Streamer Imaging
Least-Squares Dip Angle 4D Migration for OBN and Towed Streamer Imaging
The migrated dip-angle domain provides a powerful opportunity to distinguish 4D noise from signal based on similarity filtering applied to data decomposed by position, frequency, and geological dip. However, 4D signal protection is problematic when the signal itself forms from differences between baseline and ...
