Abstract
An analysis of the arrival time of scattered noise indicates that NMO and apparent dip of scattered noise exhibit azimuth dependence. For isotropic scattering, in-line scattering at ranges near 0 degree azimuth and sideswipe from 90 degree azimuth should dominate the seismic section. Actual marine data displayed in various data gathers illustrate these characteristics of scattered noise and also correct a common misconception about the appearance of scattered noise. The analysis suggests the use of CDP stacking and velocity filtering to attenuate the scattered noise. The combined effect shows a total reduction of scattered noise by 21 dB for the frequency bandwidth from 20 to 32 Hz.--Modified journal abstract.
