Triaxial induction tools are used in well logging to efficiently measure formation anisotropy including reservoir rocks that show anisotropy, such as thin laminated reservoirs. Dielectric tools are mainly used to detect fresh water and carbonate. They are vital in distinguishing thinly laminated shale oil/gas detection. Dielectric tools have higher working frequency than triaxial induction tools. In this thesis, an analytical method is used to simulate the responses of triaxial induction tools in one-dimensional multi-layered transverse isotropic formation with both the borehole and invasions neglected. Dielectric tools have the same basic formulations as triaxial induction tools except there only have two directions. Given the wide use of dielectric tools in the industry, having a simulation method that can simulate dielectric tools with speed and accuracy is important. Thus, frequency limitation for the simulation method is studied in this thesis to determine if this simulation method can simulate dielectric tools.
