Here we have a very typical Gulf Coast example comparing a PSTM image to WIT's RTM image. First, notice that the frequency content of RTM is similar to PSTM. econd, notice how fault plane reflections are imaged by RTM, and amplitudes truncate sharply against the faults. Moreover, the fault geometry makes more sense with RTM. WIT's 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 vendors.

• Cosmin Macesanu presented an SEG Abstract at the 2011 meeting which describes how WIT's implementation of TTI RTM is superior to the approximations made by other authors.

• We made a presentation at the 2011 AAPG which has many field data examples of WEM and RTM.

• We made a presentation at the 2011 AAPG which has many field data examples of WEM and RTM.

• We use two patent-pending methods to estimate velocity: Migration Velocity Focusing Analysis (MVFA) and WEM Angle Gather update. We presented two abstracts at the 2008 SEG meeting, a case study given by Morgan Brown and a theory paper given by Joe Higginbotham. WIT's own Cosmin Macesanu presented the theoretical aspects of our angle decomposition technology to a highly technical audience at BP's February, 2010 Technical Luncheon.

• February, 2010 Permian Basin Geophysical Society Luncheon - This talk highlighted the performance of our two-phase velocity model building methodology on a South Texas case study, West George West, that we market with our collaboration with ECHO Geophysical.

• April, 2009 Geophysical Society of Oklahoma City Continuing Education Seminar - This talk highlighted the performance of our WIT Depth workflows on a Mid-Continent inspired synthetic model. The comparison of PSTM and PSDM on a simple "sinkhole" example is particularly enlightening.
