Abstract

In this presentation we consider methods for estimation of seismic interval velocities using ray tracing as a key element. The methods under consideration shall be based on travel time observations, and they shall have the objective to produce a 2D or 3D subsurface 'macro model', that means, a subsurface representation for which the fine details have been omitted, whereas the main structural variations have been retained. Without doubt, such macro models show an interesting potential, f.ex., in ray-theoretical time-to-depth conversion and in model-dependent processing schemes (e.g., depth migration).
