METHOD AND APPARATUS FOR SELECTING INVERSE POWER WEIGHTING PRIOR TO VERTICALLY STACKING ACQUIRED SEISMIC DATA FOR SUPPRESSING NOISE

摘要

ABSTRACT OF THE DISCLOSUREA method and apparatus are disclosed for signal-to-noise optimization of seismic-trace signals duringseismic prospecting utilizing plural initiations of a lowenergy surface seismic source. The method and apparatusoptimize signal-to-noise ratio by vertically stacking,that is, summing, inverse power weighted seismic-tracesignals from each of the plural initiations wherein theexponent used for weighting is selectable for optimizingthe signal-to-noise ratio of the composite seismic-tracesignal. The range of exponents provided is correlated tothe range of ambient noise, including nonstationary noise,commonly encountered during seismic prospecting, espe-cially vibroseis seismic prospecting, for the purpose ofoptimizing the quality of seismic-trace data.
