Annotation	Vetores de polarizacao e componentes verticais de vetor de vagarosidade recebidos durante o walkaway VSP podem ser usados para determinacao de parametros anisotropicos no receptor no poco. Nos exemplos sinteticos, mostramos qualidade da estimativa local de parametros anisotropicos e de orientacao de eixe de simetria do meio TI invertidos de dados da onda P gerada ao lado de um perfil de walkaway VSP.
Description in English	A walkaway VSP provides an opportunity of local determination of anisotropy parameters in a borehole from recorded polarization vectors and vertical components of slowness vectors. On synthetic examples, we study quality of the estimates of the local transverse isotropy (TI) and of the orientation of its symmetry axis, from P wave data generated along a single line of the walkaway VSP.
