Abstract
A method for quantitatively distinguishing seismic events on a seismic record for inferring changes in the geological character of the subterranean formations. Reflection coefficients are obtained for such seismic events and a first set of attributes indicative of amplitude variations in the offset seismic signals corresponding to the seismic event as a function of incident angle are obtained therefrom. The first set of attributes provide a seismologist with a diagnostic tool for quantitatively evaluating subtle changes in the seismic event. A second set of attributes which are functions of the first set of attributes provide the seismologist with additional diagnostic tools for evaluating subtle changes in the seismic events.
