Abstract
Recorded seismic traces are gathered into common offset groups. Within each group, the traces are arranged according to shot point number. Mean and standard deviations are determined for each trace. High frequency amplitude variations in the mean and standard deviations caused by variations in source strengths and receiver calibrations are removed to produce traces of low frequency amplitude variations representing subsurface geology or wave propagation effects.
