Inverse Scattering Series Internal Multiple Attenuation in the Common-Midpoint Domain

Internal multiple prediction remains a high-priority problem in seismic data processing, such as subsurface imaging and quantitative amplitude analysis inversion, particularly the common-midpoint (CMP) gathers, which contain multicoverage reflection information of subsurface. multiples, generated by unknown reflectors complex environments, can be reconstructed with certain combinations events using inverse scattering series internal algorithm, is usually applied to shot records source–receiver coordinates. The computational overhead one major challenges limiting strength multidimensional implementation even coupled plane-wave domain. In this paper, we first comprehensively review domain propose new scheme achieving 2D attenuation 1.5D algorithm CMP domain, significantly reduces burden. Moreover, quantify difference behavior for shot/receiver gathers on tilted strata. Numerical errors shows that more capable handling dipping generators than it able predict accredited traveltimes multiples caused small inclinations. For cases large inclination, predictions fail both require full algorithm. To attenuate large-dipping strata, modified version proposed based results show seen simple benchmark example are correctly predicted
