The sections on imaging are clearly the heart of the boo–this chapter contains a discussion of zero-offset poststack migration, including time migrations, and chapter 6 discusses prestack migration. The wide selection of algorithms are from what we call the migration hierarchy, but not all of those algorithms are covered completely. Considerable importance is placed on the impact of aliasing and on how full wave-equation-based methods function in exactly the same manner as much simpler approaches, although they are more difficult to understand.
