Seismic True-amplitude Imaging
Kirchhoff migration, the inverse process can be called an isochron stack, or
simply Kirchhoff demigration. The concept of true amplitude in connection with
Kirchhoff demigration follows immediately from its definition for Kirchhoff
migration.

... limits 1990–2001 DMO + 3D zero-offset constant- velocity preSTM, followed by
a demigration of the stack and then 3D postSTM Constant-velocity phase-shift (
Stolt) migration, zero-offset preSTM, and subsequent demigration, in conjunction

The Seismic Velocity Model as an Interpretation Asset
Demigration. An inverse operation to migration, applied to seismic data or
horizon interpretations made on migrated data. If demigration follows migration,
and if the same velocity field is used for both, then the output of demigration is the
same ...
The surface-related multiple modeling technique presented here involves using
the prestack demigration of a migrated volume and subsequently simulating the
reverberations of primary energy within this volume. It assumes that the migrated
...
includes diffracted wave branches. This has to be so because, corresponding to
Kirchhoff migration, also demigration sums up all possible contributions to a
given point in the time section to be constructed. Modeling by demigration
appears to ...

Extended Abstracts Book: Oral presentations
In the case of using modeling by demigration for the simulation of a seismic zero
offset (ZO) section, the idea of constructing an AMS can be directly applied. All
necessary quantities (i.e., the stretch factor and the reflection coefiicient) are ...

The weight function used in the 3D time-migration algorithm produces a true-
amplitude image gather when the medium velocity is constant, i.e., the output
amplitudes are proportional to the reflection coefficients. Also, the applied
demigration ...
