| Abstract | Recordings of a multimeasurement towed streamer are subject to several different sources of noise that can negatively impact the useful signal content. Most of the conventional noise attenuation is performed in the shot domain. In this paper, we analyze the behavior of low frequency noise in domains other than the shot domain and exploit the fact that some noise that is coherent in the shot domain turns incoherent in other domains, e.g., the common-offset domain or the common-receiver-point domain. This noise randomization is used to introduce filters that can give a noise reduction of several dB in the low frequencies (< 30 Hz) while preserving signal fidelity. We demonstrate the noise attenuation capabilities on data from a survey carried out in the North Sea. |
