BPSDM

Beam Pre-Stack Depth Migration

BPSDM consists of three important steps; decomposition, migration, and reconstruction. Decomposition is a multidimensional slant stack which decomposes the data into a basis of seismic wavelets. Each wavelet has a center location and determined dip components. These contribute to the properties of the wavelet. Migration computes a point to point mapping between the unmigrated and the migrated wavelet centers. Reconstruction composites each wavelet into its local region in migrated space and outputs seismic depth traces. See
