Paper presented at the SEG/AAPG/SEPM First International Meeting for Applied Geoscience & Energy, September 26–October 1, 2021
Paper Number: SEG-2021-3583530
... Marchenko algorithms also require the up/down components of the Marchenko equation for the Green’s function retrieval. We use the Marmousi model to retrieve the Green’s function without using the up/-down components of the Marchenko equation and show that the retrieved Green’s function matches...

The solution of the direct method can be found through two distinct approaches: the first is an iterative procedure based on the Neumann series expansion, whereas the second employs a least-squares based formulation. Starting from Marchenko’s equations, we obtain a system...

... an adaptive double-focusing method for applying source-receiver Marchenko redatuming to field data. Receiver redatuming is achieved by a first focusing step, where the cou- pled Marchenko equations are iteratively solved for the one- way Green s functions. Next, source redatuming is typically performed...
