Method for noise suppression in the stacking of seismic traces
This patent describes the method of optimizing signal-to-sporadic noise in a stack of related seismic traces where the individual seismic traces are acquired in an environment where noises of a time-variant and of a time-invariant nature are present. It comprises removing gross amplitude anomalies from each of the seismic traces to produce anomalies-reduced seismic traces, establishing a plurality of weight functions, each one of the weight functions being in a one-to-one correspondence with one of a plurality of the anomalies-reduced seismic traces, summing all of the weight functions to produce a weight stack, applying each one of the weight functions to each corresponding one of the anomalies-reduced seismic traces to obtain a weighted seismic trace, summing all of the weighted seismic traces to form a weighted trace stack, and dividing the weighted trace stack by the weight stack to produce an optimized stack trace, to optimize the signal component and to reduce the noise component.
