Subsurface structures, as well as seismic amplitude and waveform signatures associated to rock properties, should ultimately be imaged in depth. Currently available seismic depth imaging methods can deliver images that fulfill those goals. However, the performance of those methods is heavily dependent on the requirement of having an accurate model of velocity and other (anisotropy, attenuation) parameters that govern wave propagation in the subsurface. On the other hand, time imaging methods do not depend on accurately modeling wave propagation but rather on approximately describing the traveltime of seismic events. While those approximations perform poorly in areas with complex geology and...
