Here we have a very typical Gulf Coast example comparing a PSTM image to
WIT's RTM image. First, notice that the frequency content
is similar to PSTM. Second, notice how fault plane reflections
imaged by RTM, and amplitudes
truncate sharply against the faults.
Moreover, the fault geometry makes more sense with RTM
depth migrations can handle isotropic, VTI, and TTI media.
You'll be surprised at the relatively low cost of RTM. Because of
the low cost of modern high-performance computing, we're able to offer an
entire workflow of wave equation PSDM velocity model building, RTM, and
attributes for around the cost of basic time processing from larger
The key to successful depth imaging is high quality velocity analysis.
The image at right shows WIT's final velocity model from a typical Gulf
Coast project, overlaying the RTM image. Note how WIT's dense angle
gather velocity updates, using WEM or RTM angle gathers, can detect
short-scale velocity variations across faults and in geopressure zones.
We can build fully anisotropic earth models and tie all available well
