This dissertation presents numerical and pseudoanalytical modeling techniques for the analysis of electromagnetic well logging tools in complex geophysical formations. The well-logging tools modeled here include measurement-while-drilling/logging-while-drilling (MWD/LWD) tools employing horizontal coil and for tilted-coil antenna ar-rays. The electromagnetic response of such tools are studied in cylindrical layered formations, including eccentric borehole, dipping bed layers, and/or anisotropic con-ductivities. The three main techniques used for modeling are the finite-difference time-domain (FDTD), a pseudoanalytical method, and numerical mode-matching. The FDTD method is implemented three-dimensional (3-D) cylindrical coordinates to handl...
