Vibroseis Processing

Summary

The Vibroseis system of recording seismic data employs a fundamentally different approach to methods using an impulse source such as dynamite. Instead of attempting to input all the energy in one short instant in time, each frequency is vibrated independently with the frequency of vibration being gradually changed until the entire frequency range that it is desired to input has been vibrated. Because of this difference in recording technique, Vibroseis data needs to be processed in a different manner compared with other types of seismic data, in order that it may be presented in an interpretable form. The purpose of this chapter is to outline aspects of data processing which are peculiar to Vibroseis data with particular emphasis on recent developments in this area.
