For transverse isotropy with a vertical symmetry axis (VTI media), P -wave reflection data alone are insufficient for building velocity models in depth. Here, we show that all parameters of VTI media responsible for propagation of P and SV -waves (the P -wave and S-wave vertical velocities VP0 and VS0 and the anisotropic parameters and δ) can be obtained by combining P -wave traveltimes with the moveout of PS-waves converted at a horizontal and dipping interface. Using converted modes, rather… CONTINUE READING
