ABSTRACT:
Time-invariant multichannel seismic data filters are applied to seismic data traces for rejecting coherent noise signals within a time-space window. In one embodiment, these filters are applied for rejecting all signals having the same trace-to-trace slopes as the coherent noise signal. Segments of the filtered traces that are within the time-space window are added to corresponding segments of unfiltered traces outside of the time window for producing reconstituted time-variantly filtered traces. In another embodiment, these filters are applied for rejecting the coherent noise signals and passing all other signals within the time-space window and passing all signals outside of the window for producing time-variantly filtered traces.
