Abstract
The amplitude of a seismic wavefront travelling through a heterogeneous rock matrix decreases due to (1) absorption or intrinsic attenuation, i.e. conversion of seismic energy to heat, and (2) apparent attenuation by scattering, i.e . transfer of seismic energy to later arrival times and other propagation directions. For a lithologic interpretation of seismic data it is highly desireable to separate both effects, for example by analyzing VSP or cross-hole data.
