Imaging is the most computationally demanding and data-intensive component of seismic processing. Therefore, researchers have spent considerable effort in devising effective imaging strategies that yield accurate images but are computationally affordable. The most general and most expensive types of migration are those that operate directly on the entire prestack data set; thus, they are called full prestack migrations. All other imaging methods are designed to approximate full prestack migration; that is, they aim to achieve the same image accuracy but at a fraction of the computational cost. In this chapter, we analyze the main characteristics and the computational costs of 3D prestack migration. An understanding of these features is important if we are to determine when full prestack migration is required and to evaluate its several available approximations.
