Seismic-reflection data are used in reservoir characterization not only for obtaining a geometric description of the main subsurface structures but also for estimating properties like lithologies and fluid contents of the target levels of interest . To this end, a rock- physics model (RPM) is incorporated into a seismic inversion scheme, such as amplitude versus angle (AVA) inversion (Grana and Della Rossa, 2010) or full-waveform inversion (Bacharach, 2006), to directly derive petrophysical rock properties frompre-stack seismic data. The outcomes of petrophysical-seismic inversion provide reservoir property maps to reservoir engineers for field appraisal, selection of optimal well location, and production enhancement (Bosh et al., 2010). A rock-physics model is a generic transformation ( f RPM ): (1) The RPM relates the rock properties (which typically are porosity - φ -, water saturation - Sw - , shale content - Sh -) and depth ( z ) to the pressure conditions, to elastic attributes (such as P-wave and S-wave velocities - Vp , Vs - and density). A rock-physics model can be based on theoretical equations (Avseth et al., 2005), or on empirical set of equations derived from available information (e.g. well-log or core measurements) for the specific case of interest
