Abstract
Fast Beam Migration is a super-efficient algorithm that is two orders of magnitude faster than the industry standard Kirchhoff depth migration, and at the same time images multi-pathing energy, a property that is typically associated with wave-equation migration algorithms. The faster and more accurate imaging step allows for more iterations of velocity model building (50-100 iterations, instead of the current 5-10), which enable the processing team to enhance the seismic resolution and imaging of complex geologic structures. Improved velocity models in combination with FBM or wave-equation imaging can provide much greater resolution and accuracy than what can be accomplished today with standard imaging technology.
