Claim One:
1. 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, which comprises removing gross amplitude anomalies from each of said seismic traces to produce anomalies-reduced seismic traces, establishing a plurality of weight functions, each one of said weight functions being in a one-to-one correspondence with one of a plurality of said anomalies-reduced seismic traces, summing all of said weight functions to produce a weight stack, applying each one of said weight functions to each corresponding one of said anomalies-reduced seismic traces to obtain a weighted seismic trace, summing all of said weighted seismic traces to form a weighted trace stack, and dividing said weighted trace stack by said weight stack to produce an optimized stack trace, to optimize the signal component and to reduce the noise component.
