    Success of traveltime inversion in anisotropic media depends strongly on the selection of the parameterization of the medium and on an efficient forward modelling scheme. We react to these requirements by using the so-called weak-anisotropy (WA) parameters instead of stiffness-tensor elements or elastic parameters in Voigt notation, and by using the forward modelling formulae based on the weak- anisotropy approximation. In the performed tests, we use P- and S-wave traveltimes generated in a synthetic VSP (vertical seismic profiling) experiment to recover complete anisotropy of a homogeneous model. The performed tests represent a preparation step for applications of traveltime inversion in inhomogeneous anisotropic media.
