ABSTRACT:
The present invention provides a method of seismic exploration for obtaining a measure of the subterranean formation rock properties. Incident angle ordered gathers of seismic signal are processed to obtain a measure of the reflection coefficient as well as attributes descriptive of variations in amplitude of the seismic signal as a function of incident angle. Such attributes, when plotted on an angle dependent amplitude diagram, are transformed into a most probable estimate of the subterranean formation rock properties as well as a diagnostic of relative lithology and pore fluid contrast.
