- W2323621311 abstract "The slowness information is being used in seismic imaging and velocity model building algorithms. The use of this kinematic attribute to stack locally coherent events can increase the signal-to-noise ratio, improve image quality and reduce artifacts of the Kirchhoff imaging. Following this concept, we present a simple combination of classical Kirchhoff prestack depth migration (PreSDM) and a local linear stack based on the horizontal surface slowness information. This modified Kirchhoff migration was implemented to include the linear stacks for all horizontal slownesses determined from travel-time tables calculated during the migration process. We apply this slowness-driven Kirchhoff prestack migration algorithm to sparse synthetic ocean bottom data (OBS) data and the kinematic migrated image show significant improvements in image quality and a great reduction in the migration artifacts compared to a conventional Kirchhoff algorithm." @default.
