Patent ID: 8743656

Claim:
A method of seismic data processing, wherein the data includes at least one set of seismic traces, with each trace including a signal recorded by a sensor after having been propagated in a subsurface area, with the signal being defined by an amplitude as a function of time, including the steps of: migration of at least one set of seismic traces according to an initial time-velocity model; picking in the time-migrated data one or more event(s) corresponding to one or more subsurface reflector(s) so as to obtain facets locally approximating the respective event; performing kinematic demigration of the picked time-migrated facets so as to obtain processed seismic data comprising a set of facets and a set of attributes associated with the facets, wherein at least one set of attributes is used to produce one or more images representing the characteristics of said subsurface area.
