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. WebSeveral conventional fracture prediction methods were tested as well as a new type of pre -stack depth migration called Dulplex Wave Migration (DWM). We concluded that the DWM technique was the most reliable method for fracture …

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. WebThis paper describes a Kirchhoff implementation of Duplex Wave Migration (DWM) that removes these limitations and we illustrate how DWM can provide an ... while at the same time automatically attenuating all energy other than the duplex wave energy (DWE).
