ABSTRACT:
The present invention relates to a method for identifying and separating the effects of elastic and anelastic formation properties in a seismic signal representative of the earth's response to seismic energy imparted therein. The seismic signal is decomposed into a measure of the absorptive contrast and impedance contrast across reflecting boundaries in the earth's subterranean formations. The resulting measures of impedance contrast can be used to obtain a measure of the earth's elastic properties. The resulting measures of the absorptive contrast can be used to obtain measures of the earth's anelastic properties.
