It is shown that Vendian terrigenous deposits are characterized by anisotropic mechanical properties. Transversely isotropic model with vertical axis of symmetry (TIV) was used for geomechanics model construction of one of the largest field in East Siberia. In this paper an algorithm and main aspects of geomechanical modeling with respect to anisotropy of the rock mechanical properties are presented on example of particular field. The impact of anisotropy on results of geomechanical modeling is demonstrated, justifying the need to take into consideration anisotropic effects. It is shown that anisotropy of rock mechanical properties has to be taken into account for more accurate results of different studies such as avoiding instabilities while drilling, hydraulic fracturing treatment design etc.
