P098 P-WAVE NONHYPERBOLIC MOVEOUT INVERSION IN AZIMUTHALLY ANISOTROPIC MEDIA: METHODOLOGY AND REAL-DATA EXAMPLE IVAN VASCONCELOS and ILYA TSVANKIN Center for Wave Phenomena Colorado School of Mines Golden CO 80401 USA Abstract The azimuthally varying nonhyperbolic moveout of P-waves in orthorhombic media can provide valuable information for characterization of fractured reservoirs and seismic processing. Here we present a technique to invert long-spread wide-azimuth P-wave data for the orientation of the vertical symmetry planes and (1) (2) five key moveout parameters – the symmetry-plane NMO velocities V nmo and V nmo and the anellipticity parameters η (1) η (2) andη (3) .
