The mapped CIG gathers can be considered "complete" representations of the
scattering event, and as such, can be
processed subsequent to migration to correct for defects in the input data and
modeling procedure, and to accentuate
any physical aspect of interest.
The potential impact for seismic imaging and interpretation is twofold. First,
this mapped domain allows for data correction normally performed before or
during the migration, such as data reconstruction and anti-aliasing. Second, new
classes of physically derived images be-

and at Intel. He holds a Ph.D. in theoretical chemistry from Hebrew University.

come available to the interpreter. These
can greatly enhance the certainty of the
interpreter's understanding of the geology.
This has been demonstrated for directionality derived imaging. The significant
increase in fault and fracture zone detection
opens new prospects for seismic processing and interpretation.
