oa Applied Seismic Inversion for Estimating Velocity-Depth Models

Processing and inversion of seismic data differ in one fundamental respect -- the output from processing often is displayed in time, and the output from inversion is intended to be displayed in depth. The main goal in inversion is to estimate a geologically plausable subsurface velocity-depth model, which comprises two sets of parameters -- layer velocities and reflector geometries. To resolve the well-known velocity-depth ambiguity in inversion, these parameters need to be estimated, independently.
