WebThis paper describes examples of mapping fracture zones in carbonate reservoirs using duplex wave migration (DWM). This method is used following conventional pre-stack depth migration with a... 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.

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 photographs mountains

"WebSummary Duplex Wave Migration (DWM) images vertical features via a second reflection point, the first hit being off a strong mirror surface. In the HV (Horizontal first) mode, the shot to mirror path is moved to all possible positions on the mirror, moving the shot to the mirror under the target zone for migration.
