Abstract

"A feasible method of estimating the attenuative properties of a layered earth medium from a reflection seismogram has been developed. An average attenuation factor of n layers in the least squares sense is designated as ß and its usefulness in real applications is investigated. Techniques of extracting dissipation factors from both noise free and noisy reflection seismic traces are discussed. In order to describe the change of the factors with an increase of depth, an average dissipation curve the form of which is similar to the average velocity of layered medium is also introduced. Both the ß and the average dissipation curves are estimated using real seismic data. The result reveals that dissipation factor of each individual layer obtained shows highly fluctuating characteristics. However, both ß and the average dissipation curve exhibit reasonably reliable statistical regularity"--Abstract, page ii.
