Ursin (Norwegian University of Science & Technology) SUMMARY We present an analytic approach to the description and modeling of the 3-D acoustic waves in complex multilayered overburden. The total scattered wavefield is split into a branching sequence of multiply reflected/transmitted wavefields which can be directly identified with the intermediate reflectors generating them. Each wavefield is represented by
