WebTo solve the new wave equation, we use a stable explicit extrapolation method in the time direction and handle the lateral velocity variations in both the space and wavenumber domains. Unlike the conventional explicit finite‐difference schemes, this new method does not suffer from numerical stability or numerical dispersion problems. WebDuplex wave migration fits in the processing flow following conventional 2D or 3D prestack depth migration. The input data is the same data set and geologic depth model that is input to conventional depth imaging routines. The only additional information that must be supplied is the .

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 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). In this paper we will present an example of 3D DWM on a 3D data set from the WCB to

Designing fiber optic cabling for data centers requires a strategy to balance the cost/benefit of the opto-electronics against the investment choices for fiber optic cabling. One basic trade-off is a choice between parallel and duplex fiber links.
