An inverse-scattering series method for attenuating multiples in seismic reflection data
TL;DR: In this paper, a multidimensional multiple-attenuation method is presented that does not require any subsurface information for either surface or internal multiples. But it does not consider the relationship between forward and inverse scattering.
Journal ArticleDOI
Inverse scattering series and seismic exploration
Arthur B. Weglein,Fernanda Vieira Araujo,Paulo M. Carvalho,Robert H. Stolt,Kenneth H. Matson,Richard Coates,Dennis Corrigan,Douglas J. Foster,Simon A. Shaw,Haiyan Zhang +9 more
TL;DR: In this paper, the authors present an overview and a detailed description of the key logic steps and mathematical-physics framework behind the development of practical algorithms for seismic exploration derived from the inverse scattering series.

Proceedings ArticleDOI
Inverse Scattering Internal Multiple Attenuation: Results From Complex Synthetic And Field Data Examples
TL;DR: In this paper, a pre-stack amplitudepreserving processing technology that is effective in complex geologic environments is presented. But the authors do not consider the use of multiple suppression in seismically challenging areas where conventional methods are no longer adequate.
Proceedings ArticleDOI
Imaging And Inversion At Depth Without a Velocity Model: Theory, Concepts And Initial Evaluation
Arthur B. Weglein,Ken H. Matson,Douglas J. Foster,Dennis Corrigan,Paulo M. Carvalho,S.A. Shaw +5 more
TL;DR: Weglein et al. as mentioned in this paper proposed a multidimensional inversion procedure that directly determines physical properties using only reflection data and a reference medium, which can be thought of as performing the following four tasks: (1) free surface multiple removal, (2) internal multiple removal and identification of medium property changes across reflectors.
