Every year, several hundred million birds cross the Mediterranean on their migration from Eurasia to their wintering quarters in Africa. As many migrants travel at night or at high altitudes, direct observations of bird migration are difficult and th

3‐D finite difference migration in azimuthally anisotropic media

SUMMARY A 3-D implicit finite-difference depth migration scheme for waves in azimuthally anisotropic media is presented. An orthorhombic model is considered where the phase velocity function for each constant azimuthal angle has exactly the same math

Reducing anisotropy and frequency dispersion by 3‐D Fourier finite‐difference migration

Autor: Dietrich Ristow, Thomas Rühl

Publikováno v: SEG Technical Program Expanded Abstracts 1996.

Fourier finite-difference (FFD) migration is extended from two to three spatial dimensions. 3-D FFD migration is a hybrid migration method containing a 3-D phase-shift operator in the frequencywavenumber domain and an implicit FD operator in the freq
