The 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. |
