Marchenko redatuming, imaging, and multiple elimination and their mutual relations

With the Marchenko method, it is possible to retrieve Green’s functions between virtual sources in subsurface and receivers at surface from reflection data focusing functions. A macro model of needed estimate first arrival; internal multiples are retrieved entirely data. The form input for redatuming by multidimensional deconvolution (MDD). redatumed response free related overburden. Alternatively, can be obtained applying a second function This process called double focusing. It more stable better suited an adaptive implementation than MDD, but does not eliminate target An attractive efficient alternative plane-wave redatuming, which retrieves responses limited number level. In all cases, image data, artifacts caused multiples. Another class methods aims eliminating while keeping surface. specific characteristic this multiple elimination that predicts subtracts orders with correct amplitude, without needing model. Like implemented as MDD process, dereverberation or oriented process. We have systematically examined different approaches imaging, using common mathematical framework.
