GEOSTEERING IN ANISOTROPIC FORMATIONS USING MULTICOMPONENT INDUCTION MEASUREMENTS

摘要

A multicomponent induction logging tool is used on a MWD bottomhole assembly (1221). Multifrequency focusing that accounts for the finite, nonzero, conductivity of the mandrel (1221) is applied. Using separation of modes, the principal components and relative dip angles in an anisotropic medium are determined. The results are used for reservoir navigation in anisotropic media.
