Marchenko Focusing Without Up/Down Decomposition

Research output: Chapter in Book/Conference proceedings/Edited volumeConference contributionScientificpeer-review


Marchenko equation enables one to retrieve the up/down components of the Green’s function. We propose an iterative scheme to relax the need for up/down separation for focusing. By presenting a visual tour, we show how to retrieve the Green’s function in the subsurface at a pre-defined location without requiring component decomposition. Our retrieved Green’s function contains accurate primary and multiple events of the heterogeneous subsurface and forms the basis for obtaining an image of the subsurface without the need for up/down decomposition.
