Coherency based time-domain imaging algorithms

Abstract

Seismic time-domain imaging is one of the most robust tools in seismic data processing. Compared with depth imaging, time-domain imaging employs a reduced number of parameters by taking effective approximations for wave propagation in the subsurface. Accurate time-domain seismic imaging as applied in very complex environments (e.g., hard rock environments) requires a novel critical thinking. In this thesis, several efficient time-domain imaging techniques have been developed and successfully applied to different seismic data sets.
