Wave-Equation Angle-Domain Imaging for Multicomponent Seismic Data

A08 WAVE-EQUATION ANGLE-DOMAIN IMAGING FOR MULTICOMPONENT SEISMIC DATA 1. Abstract Seismic images obtained by multicomponent wave-equation migration can be decomposed into angle gathers with a transformation that generalizes the equivalent construction for primary waves. A particularly simple formulation is to use all three components of the offset vector separating sources and receivers at image points. Using full vector offsets multicomponent angle-gathers are built using simple transformations that are implemented partially in the Fourier domain and partially in the space domain. 1 2. Introduction Downward wave extrapolation provides an accurate method for seismic imaging in structurally complex areas (Gray et al.
