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.
