The usual random-noise attenuation techniques use 1-D prediction operator to process 3-D seismic data line by line in the same way as is taken in 2-D data process-ing,so that they fail to make full use of signal-coherent informations in 3-D seismic data, without real full 3-D random-noise attenuation. Hence, I take 2-D rectangular prediction operator instead of common-used l-D prediction operator to make full use of coherent informations in adjacent CDP bins in 3-D seismic data,thus achieving full 3-D noise...
