Using a 1D FX Predictive Filter for 3D Seismic Data Random Noise Attenuation

Summary For some time now, FXY has been used as a standard algorithm for random noise attenuation on 3D seismic data. Recently, however, users noticed that, when signal/noise ratio is low, FXY is not as successful. In this paper, we will demonstrate that a series of 1D FKxY predictive filters is superior to the 2D FXY filter in the presence of significant random noise.
