Seismic images are crucial to today's exploration and reservoir monitoring. '3D Seismic Imaging presents fundamental concepts and cutting-edge methods for imaging reflection seismic data. The book coherently presents the main components of seismic imaging - data-acquisition geometry, migration, and velocity estimation - by exposing the links that intertwine them. The book emphasizes graphical understanding over theoretical development. Several synthetic and field data examples illustrate the presentation of mathematical algorithms. The volume includes a DVD that contains a subset (C3-narrow-azimuth classic data set) of the SEG-EAGE salt data set and of the corresponding velocity model. The DVD also includes a complete set of PDF slides that can be used to teach the material presented in the book.
