Diversity stack as an editor of non-stationary noise in nonexplosive seismic
Wind noise, traffic noise, railway noise, and non-stationary impulsive noise significantly degrade seismic data quality in many exploration areas. Vertical stacking at the acquisition stage or two-dimensional noise suppression procedures (such as FK) at the data processing stage can not completely attenuate high-amplitude noise of listed types. At the same time, non-stationary noise can be efficiently suppressed by diversity stacking. This procedure does not distort initial relative amplitudes, does not slow down the acquisition works, and consequently can be recommended for wide adoption. The parameters of the diversity stacking procedure should be defined during field trials.
