Transversely isotropic with vertical symmetry axis (VTI) is a practical assumption for wave propagation environment in many 2D seismic data, due to its acceptable accuracy and limited number of input parameters. Explicit VTI traveltime approximations are commonly used in many seismic data processing and inversion algorithms. In this study we propose a new traveltime approximation for P-wave propagation in VTI media that is more accurate than the previously reported most accurate approximations. We compare its accuracy, and show that it can outperform other three-parameter approximations in velocity analysis and normal moveout correction.
