Fazemos a analise de estimativa de anisotropia local em meios anisotropicos arbitrarios atraves de dados das ondas qP em experimentos de VSP multiazimutal com multiplas fontes. Os dados sao componentes verticais de vetores de vagarosidade e polarizacao. Nos estudamos efeitos da escolha de meio da referencia e do vetor normal a frente de onda.

Inversion scheme for the determination of anisotropy in a vicinity of a receiver situated in a borehole from the data obtained during a multiazimuth multiple-source offset VSP experiment is studied. The data consist of vertical components of slowness vectors and of polarization vectors of direct and reflected qP waves.
