Wavefield Migration

The wavefield migration function in Divine can be applied to Microseismic or active seismic data sets such as VSP, crosshole and surface reflection configurations. The survey configuration and imaging may be 2D or 3D.

 

The illustration shows pre-stack depth migration of a VSP data set. The migration region has been limited to the area of reflection point coverage from the middle to the left of the survey region. The reflector aperture covers reflector dips of +- 3° plus a taper length of 5°. The wavefield has been normalised with respect to the reflection point hit count and the traces are plotted as a contour plot with trace by trace scaling inserted into the velocity model.

 

The main feature of the migration is an offset in the reflectors across a possible reverse fault.
