Abstract
The present disclosure includes a method for reducing noise in seismic data using a frequency dependent calendar filter. The method for reducing noise in input seismic trace data includes obtaining a plurality of input seismic trace data, the plurality of input seismic trace data including a plurality of controlled signals and a plurality of uncontrolled signals, identifying a frequency content of the plurality of uncontrolled signals, and selecting a frequency dependent calendar filter based on the frequency content of the plurality of uncontrolled signals. The method further includes applying the frequency dependent calendar filter to the plurality of input seismic data to generate a plurality of output noise-reduced seismic traces. The present disclosure also includes associated systems and apparatuses.
