Applications of Interbed Multiple Elimination

Abstract

Multiple contamination both surface related and interbeded are common and known to hinder the interpretation, reservoir characterization and inversion studies. Surface related multiple is always present and strong on marine data, but not often a problem on land data. Interbed multiple is rather dependent on the subsurface structures and not always obvious, however in presence of strong subsurface reflectors, interbed multiple contamination could be marked, this article mainly focus on IME – Interbed Multiple Elimination. Two methodologies including data driven Extended SRME IME in combination with radon transform based demultiplex and ISS (inversion scattering series) based IME are introduced. Good demultiple results are demonstrated by case study.
