(average of 20 minutes per Subtopic)

Describes the process of common midpoint stacking and introduces alternate forms of stacking. Examines the use of two-dimensional filters in separating different arrivals on the basis of their characteristic velocities. Discusses pre-stack and post-stack filtering processes, and the use of band pass filters, time variant filters and filter panels. Reviews different methods for displaying final record sections based on the needs of the seismic interpreter.
