Characterization and simulation of transverse noise waves of a Multi-sensor solid streamer

Résumé

Multi-sensor streamers have many advantages over traditional hydrophone-only streamers. In particular, they provide a measure of the pressure gradient which allows for data driven only broadband de-ghosting. This results in an improved subsurface image and allow the streamer to be towed deeper, reducing noise and operational downtime. However, the use of particle motion sensors is limited due to strong vibration noise waves they are subjected to. In this article a detailed characterization of these waves is proposed. Reviewing the classical model of the propagation of transverse waves, a new model of their propagation velocity is obtained. This one allows to explain the velocity difference observed on field data between the waves that go down and up the streamer. A simple attenuation model is proposed to estimate their amplitude decay as they propagate along the streamer. Knowing these new characteristics, a simulation of these waves is performed that matches the real data with high accuracy.
