(TU Delft Applied Geophysics and Petrophysics) Date 2022 Abstract Marchenko imaging can be seen as an internal multiple elimination scheme in imaging domain. By solving coupled Marchenko equations, the measured seismic data can be correctly redatumed to the subsurface with source positioned at subsurface and receivers positioned at acquisition surface. Then, the artefact-free image of the source point can be retrieved by multi-dimensionally deconvolving the redatumed up- and downgoing seismic data. The Marchenko Multiple Elimination scheme, derived from coupled Marchenko equations, is a data domain multiple elimination scheme. It can successfully predict and remove all orders of internal multiple reflections without model information or adaptive subtraction. The data domain multiple elimination scheme surgically removes internal multiple reflections without touching primary reflections. In this paper, we give a detailed comparison of both imaging domain and data domain Marchenko multiple elimination schemes. One synthetic model is used to illustrate the performance of both schemes and, the advantages and disadvantages of both schemes are discussed in detail.
