Homogeneous Green's Function Retrieval on Field Data Using the Marchenko Method

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

Abstract

Retrieval of the homogeneous Green's function is often done using a single-sided boundary, even though the theory states that an enclosing boundary is required. In recent years the theory has been modified to create a single-sided representation. This is done by using the Marchenko method, to redatum the wavefield from the boundary to a virtual receiver location inside the medium. The results on synthetic data have been encouraging, but on field data this method is largely unproven, due to the fact that the Marchenko method assumes that the medium is lossless, which in practice it is not. We have shown how to apply the classical representation and that it does not deliver the desired result on the field data. We have also demonstrated how to apply the new representation on the field data and that the result has improved over the classical representation. We visualize the result as snapshots over a region of interest to show the propagation of the wavefield through the medium.
