Abstract：We discribe primarily in this paper the basic principes of the modules for seismic data prestack random noise attenuations in GeoEast processing system. Then we discuss the function of some key parameters in the module which include the weighting coefficient of energy ratio, the extrapolation of predictive operators, the predictive operator length, the start and end frequency for noise attenuation, the time window length and its overlap percent, the spatial window length and its overlap percent. These parameters selection effect the CPU time. Some skills of parameters selection are given in the paper, which might be helpful for GeoEast users.
