Exercise 8-1. Consider the zero-offset x − t section depicted in Figure 8.E-1. Using the velocity-depth model in the same figure, sketch the depth-migrated x − z section.

Exercise 8-2. Identify the prominent sideswipe energy on Lines I-181 and I-151 in Figure 8.4-2 (right column).

Exercise 8-3. In areas with complex overburden, which one is more important — 3-D poststack depth migration or 2-D prestack depth migration?

Exercise 8-4. How would the geometry of the subsalt target reflectors labeled in yellow in Figure 8.E-2 behave on a section from an image volume created by 3-D poststack depth migration?
