Nonstationary L 1 adaptive subtraction with application to inverse scattering multiple attenuation

Scott Keating, Jian Sun, Pan Pan, Kris Innanen


A method for adaptive subtraction in conjunction with internal multiple prediction by inverse scattering series is investigated. An L 1 , nonstationary adaptive subtraction is found to minimize mistaken matching to primaries while still allowing for a large degree of multiple removal. This adaptive subtraction is tested on both synthetic and physical modeling data. The method proves to be effective, and avoids unwanted matching to primaries.
