Migration of seismic multiple reflections

LIU YiKe;LIU XueJian;ZHANG YanBao;InstituteofGeologyandGeophysics,Chinese Academy of Sciences;  
Seismic data contains various kinds of multiple reflections,including surface-related and internal multiples.Conventional seismic imaging utilizes reflections only and the multiples,being traditionally treated as noise,are removed before imaging.Actually,multiples penetrate into the subsurface several times and contain abundant reflection information. Multiples sometimes can provide higher fold and better illumination for the subsurface than primaries.Multiples usually travel with longer wave paths and cover larger areas than primaries in the media,and multiples can penetrate into the earth to illuminate the shadow zones which primaries cannot reach.Consequently,migration of multiples can sometimes provide better subsalt images compared to conventional migration which uses primary reflections only.We modify conventional reverse time migration(RTM)so that surface-related multiples can be used as constructive reflection energy for subsalt imaging.This approach replaces the impulsive source wavelet with the recorded data containing both primaries and multiples and uses predicted multiples as the input data instead of primary reflections.In the reverse time migration process,multiples recorded on the surface are extrapolated backward in time to each depth level,and the observed data with both primaries and multiples are extrapolated forward in time to the same depth levels,followed by a cross-correlation imaging condition.For RTM of all-order multiples,however,the main challenge is that undesired cross-correlation between forward and backward propagated seismic waves generate so many crosstalk artifacts.The crosstalks may distribute in the whole image profile,which can destruct the true image of reflectors and mislead the interpreting result of a migrated image.We apply the least squares migration scheme to these two successive orders of multiples.Our method is denoted as the leastsquares RTM using controlled-order multiples(LSRTM-CM).LSRTM-CM can provide a very clean section by reducing almost all artifacts.With limited iterations used,LSRTM-CM can provide a very interpretable image section,as LSRTM-CM can further enhance the image in detail by suppressing the crosstalk artifacts,balancing the amplitude,and improving the resolution.Internal multiples are usually generated below coal seams,salt domes,basalt flows and other geological formations with high velocity contrasts,and behave differently compared to primary and surface-related multiples.We propose a reverse time migration method which is capable of handling internal multiples.The method first extracts internal multiples from the wavefield,followed by extrapolating those multiples backwards in time through the subsurface.For this method,internal multiples are separated by inverse scatter series and used as data in reverse time migration.Numerical tests show that a wider coverage and a more balanced illumination of the subsurface can be achieved by migration of multiples compared with conventional migration of primary reflections.
