Extended imaging and tomography under two-way operators
Seismic images reconstructed by migration from seismic data recorded at the surface represent the earth structure at every location in the subsurface. The data are remapped into the subsurface by using a wave equation and an estimate of the earth velocity. The velocity model is of great importance for obtaining accurate seismic images and for understanding the subsurface reservoir properties and conditions. In this thesis, I focus on structure and velocity estimation from surface seismic data. In order to invert for the velocity model, I seek to improve the synchronization and consistency ...
