Abstract

See full text

This disclosure is directed to systems and methods for stacking seismic data. The methods receive seismic data collected from a survey of a subterranean formation. A gather of seismic data may have flattened reflection events obtained as a result of normal moveout (“NMO”) corrections or pre-stack migration. Alternatively, the gather may be an unmigrated gather with non-horizontal reflection events. A smoothed-amplitude gather is generated from the gather. Traces of the gather are stacked to generate a trace with significantly reduced noise using corresponding smoothed amplitudes of the smoothed-amplitude gather as weights.
