WebThe term duplex wave describes propagation paths with a double reflection involving a reflecting base boundary and a near vertical feature. The purpose of our study was to examine the possibility of using duplex waves to directly image vertical features. Here, … 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 … higher peak llc

WebWhen a seismic dataset is acquired all types of wave modes are recorded. These include primary reflected energy, as well as direct, multiple, shear and mode converted waves to … 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.
