Abstract
Summary
This paper presents recent advances in the area of seismic interference (SI) attenuation for towed streamer data. We show how high amplitude and broadside SI noise can be nearly perfectly attenuated as long as the interfering noise is incoherent from shot-to-shot. Furthermore, we present a new algorithm that also allows us to attenuate nearly all forms of shot-to-shot coherent noise. These algorithms have effectively eliminated the need for reshooting/timesharing due to SI noise in the North Sea, and have therefore contributed to a significant improvement in acquisition efficiency.
