SEISMISK STREAMER MED UREGELMÆSSIGT FORDELTE HYDROFONER

摘要

A seismic streamer and a method for positioning a group of hydrophones in a seismic streamer. The hydrophones in a group are spaced irregularly along the length of the streamer to reduce the influence of bulge-wave noise and flow noise on the hydrophone group response. The irregular spacing may be produced as pseudorandom deviations of the actual positions of the hydrophones from a nominal uniform spacing of hydrophones.
