AB: The inverse-scattering series is the only direct multi-dimensional inversion procedure that permits all processing objectives associated with inversion to be accomplished without knowing, or determining, either the slowly or rapidly varying part of the medium through which the waves propagate. The latter property explains why these methods are a direct response to the challenge of removing multiples and imaging beneath a complex ill-defined overburden, e.g., salt, basalt, and karsted sediments. The removal of free surface multiples, the attenuation of internal multiples, and the depth imaging and inversion of primaries are achieved by four distinct subseries, and each operates without knowledge or determination of the velocity model. We will exemplify these task-specific subseries concepts, and algorithms, with synthetic and field data. Reference: Weglein, A. B., Araujo, F. A., Carvalho, P. M., Stolt, R. H., Matson, K.
