Programa de Pós-Graduação em Geofísica.https://repositorio.ufpa.br/handle/2011/5488The triaxial or multicomponent induction tool was recently developed to solve the problems of conventional induction logging measurements in anisotropic formations. In this work are presented the triaxial induction sonde answers in reservoirs with thinly laminated sand-shale sequences. Reservoirs as these present the known macrocospic anisotropy, therefore, the results will demonstrate to the existence of both horizontal and vertical resistivity. Due the triaxial induction sonde to present two pairs of coplanar coils, which in general provide the values of vertical resistivity, this work presents initially an analytical and qualitative study of the answers obtained for coplanar array where the transmitter is considered a dipole. Also will be presented the analytical solution where the transmitter coil is evaluated as a loop of finite dimension.porAcesso AbertoPerfilagem geofísica de poçosDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOFISICA::GEOFISICA APLICADA
