The inverse scattering series and task specific sub-series(1) provide the opportunity of addressing the most
daunting and pressing challenges in exploration seismology. Those challenges often derive from the inability to
provide an adequate subsurface velocity model needed for accurate imaging in the presence of rapid varying
boundaries and/or highly heterogeneous media. The inverse scattering series has the property of allowing all
processing objectives (e.g., multiple removal, depth imaging, and non-linear AVO) to be achieved without in
principle or practice requiring or needing the velocity. There is no proxy, or surrogate for the velocity nor a search
or invariance principle nor model matching of any kind. The algorithms are direct, and distinct algorithms remove
free surface multiples, remove internal multiples or depth image primaries. We will describe and exemplify these
methods, and describe data requirements, plans and open issues.
