Abstract:
1. A logging method that comprises: measuring at least one of a signal amplitude and phase from a first receiver antenna in response to excitation of first and second transmitter antennas, wherein said first receiver antenna is positioned between said first and second transmitter antennas and tilted at a different angle than said first and second transmitter antennas; measuring at least one of a signal amplitude and phase from a second receiver antenna in response to excitation of said second transmitter antenna, wherein said first transmitter antenna is positioned between said first and second receiver antennas, and wherein said second receiver antenna is tilted at a different angle than said second transmitter antenna; generating a formation resistivity log based at least in part on measurements from the first receiver antenna; and determining a bed boundary indicator based at least in part on measurements from the second receiver antenna.
