Technical Abstract

Advances in seismic interference noise attenuation

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