Abstract / Description of output

Seismic attenuation is, in general, a combined effect of absorption (intrinsic attenuation), which is affected by lithological parameters, and scattering (apparent) attenuation, which is related to heterogeneities. Synthetic modeling studies with and without intrinsic attenuation show that the contribution of scattering attenuation is significant in fractured rock. Scattering involves no energy loss, but produces a more extended, lower amplitude wavetrain by the resulting interference. It is dependent on the nature of small-scale fluctuations in the earth parameters and is found to be frequency dependent. The purpose of this study is to examine the sensitivity of scattering attenuation at different fracture patterns characterized by different statistical properties and fracture population geometry, and to examine its use as a potential tool for the characterization of a fractured network.
