Abstract
We review the inverse scattering multiple attenuation method, describe the current state of field data application, and provide an<br>impression of anticipated future developments. In addition, we describe in detail the fundamental and intrinsic difference between<br>prediction mechanisms that derive from forward modeling, and the prediction capability that reside within a task-separated direct<br>inversion procedure. This analysis scrutinizes the logic behind the inverse scattering multiple attenuation methods and thus sheds<br>light on how multiples can be predicted and subtracted from seismic data without any subsurface information (e.g., absolutely no<br>velocity analysis) or interpretive intervention.
