METHOD FOR ATTENUATING NOISE IN SEISMIC DATA USING COMPLEX TRACE DIVERISTY FILTER

摘要

A method is disclosed for attenuating noise in seismic data. The method includes calculating a trace envelope (10) for at least part of at least one seismic trace, generating a filtered envelope (12) from the trace envelope, and transforming the filtered envelope to a filtered trace (14). In one embodiment, a length of a filter operator used for generating the filtered envelope is inversely related to a maximum frequency to be preserved in the filtered trace.
