WebA: Duplex wave migration (DWM) operator differs from the PSDM one, as the Green's function in the Kirchhoff migration is formed in accordance with the law of propagation of the duplex wave. This leads to the fact that the impulse response of the DWM operator is rotated by 90 degrees with respect to the PSDM impulse response. solihull heightshttp://tetraseis.com/ solihullhomeoptions.org.uk

"WebProspecting [7], this is the duplex wave migration (DWM). This type of migration may be compared to the common migration the impulse response of which is turned through 90°. It enables to retrieve the duplex waves from the initial wave field. The waves are named duplex waves in case they have two reflections: the initial from the sub-horizontal " - Duplex wave migration

WebConventional pre‐stack depth migration (PSDM) is capable of imaging vertical boundaries provided the geology has strong vertical velocity heterogeneity and the seismic is recorded with a very large surface aperture. This paper describes a Kirchhoff implementation of Duplex Wave Migration (DWM) that removes these limitations and we illustrate how … WebThis has led to interest in processing doubly scattered waves (also called duplex or prismatic waves) for imaging salt flanks and thus improving the location of salt boundaries in a velocity model. We used doubly scattered waves in a two-pass, one-way method to image salt flanks in a North Sea data set.
