N-07 PS-WAVE BIREFRINGENCE ANALYSIS AT THE EMILIO FIELD FOR FRACTURE CHARACTERIZATION J. GAISER 1 E. LOINGER 2 H. LYNN 3 and L. VETRI 2 Summary 1 3-D converted P to S-waves (PS-waves) provide an excellent opportunity to exploit upgoing shear-wave (S-wave) birefringence (splitting) for delineating reservoir fractures. In azimuthally anisotropic media fracture intensities and orientations are directly related to traveltime differences between the fast and slow S-wave and the polarization direction of the fast S-wave respectively. Birefringent velocity properties of the overburden must be determined and removed prior to estimating fracture properties at target horizons. The Emilio 3-D survey acquired
