diffraction hyperbola

.

migration does what

uses velocity information to zip up hyperbolae

repositions energy reflected from dipping layers

what signals don't migrate

multiples

out of the plane diffractions

etc.

how does predictive deconvolution work

 

If we can identify the input wavelet, and replicas of it, we can attempt to suppress those replicas

how to remove multiples post velocity analysis

the same as pre velocity analysis

SRME

surface related multiple estimation

Earth responce

source generates multiples, every multiple is a source etc.

big pro and big con of SRME

3D SRME is enormously intensive but you don't need to know anything about the veocity:depth model.
