Fast Beam Migration (FBM) is a very efficient Previous HitdepthNext Hit Previous HitimagingNext Hit algorithm that can be two to three orders of magnitude faster than current implementations of Kirchhoff migration. For complex subsurface regimes, the main bottleneck in a Previous HitdepthNext Hit Previous HitimagingNext Hit workflow is the number of migration iterations needed to reach an acceptable Previous HitdepthNext Hit velocity model. Using FBM allows a faster Previous HitimagingNext Hit step, which in turn allows more iterations of velocity model building. This additional refinement of the velocity model enables enhanced seismic resolution and Previous HitimagingNext Hit for complex geologic structures, including sub-salt. The main objective of using this technology in a Previous HitdepthNext Hit Previous HitimagingNext Hit workflow is to significantly decrease processing turnaround time for large 3D datasets, while at the same time produce high-resolution Previous HitdepthTop images.

During the presentation we will illustrate the application of the FBM technology to synthetic and real data sets.
