WEIGHTED SLANT STACK FOR ATTENUATING SEISMIC NOISE

A method and apparatus are disclosed for attenuating noise in seismic data including a plurality of input traces. The method includes transforming the seismic data from the space-time domain into the slant-stack domain. Seismic data having a preselected characteristic is excluded when the transforming into the slant-stack domain. The transformed data is inverse transformed from the slant-stack domain into the time space domain. The method and apparatus may include anti-alias filtering the seismic traces. The method and apparatus may include p-anti-alias filtering seismic traces.
