O18 - 05 SEISMIC MODELLING & INTERPRETATION ANALYTIC SOLUTION TO NMO-VELOCITY SURFACE IN TI MEDIA WITH AN ARBITRARY SYMMETRY AXIS Jianzhong Zhang Chen Yao Chongtao Hao Minggang Cai Institute of Geology Earthquake Administration Beijing China Summary Following the concept of NMO-velocity surface introduced by Grechka and Tsvankin we present the analytic solution to NMO-velocity surface in transversely isotropic media with an arbitrary axis of symmetry (ATI). The solution is in accordance with previous results given by some authors when limited to some special cases. Computation of effective NMO velocities in 3D layered TI media with plane dipping interfaces can be
