Surface-related multiples may severely contaminate multicomponent
seabed seismic recordings. Because conventional imaging techniques
require input data that consist of primary reflections only, significant
processing effort is commonly dedicated to attenuating multiples
prior to migration. On the other hand, surface-related multiples
provide additional illuminations of the subsurface. We present a
prestack depth-migration method that allows primary and multiple
reflections to be imaged simultaneously. Depth imaging with primary
and multiple reflections (DIPMR) involves decomposing the data into
up- and downgoing wave constituents, followed by downward extrapolation.
Artifacts generated by interference of up- and downgoing events not
associated with the same subsurface reflection points (cross-talk)
are attenuated using a 2D deconvolution imaging condition. In contrast
to existing methods, DIPMR does not require a priori information
about the source signature or directivity, because the illuminating
source wave field is extracted directly from the data themselves
via the up/down separation. Moreover, there is no need for elimination
or identification of multiples prior to migration. By including surface-related
multiples in the imaging procedure, the effective source wavefield
is stronger and the spatial aperture wider.
