Scalar and Vector Models of Constant Q Wave Propagation

P099 SCALAR AND VECTOR MODELS OF CONSTANT Q WAVE PROPAGATION ANDRZEJ HANYGA Institute of Solid Earth Physics University of Bergen All’egaten 41 N5007 Bergen Summary A rigorous scalar model and an approximate isotropic vector model of constant-Q seismic wave propagation are presented. Introduction In many applications of seismic modeling it is necessary to account for attenuation but the specific physical mechanism involved is irrelevant. This is particularly true for seismic wave propagation outside reservoir regions. In this case the constant-Q assumption seems an ideal solution since it requires just one parameter and yet it is consistent with observations over a
