主权项

1. A system comprising:
a surface source loop; a transmitter that transmits electromagnetic energy to the surface source loop; surface equipment that controls the transmitter and that analyzes received digital signals associated with electromagnetic energy transmitted by the surface source loop; a tool that comprises at least two external electrodes for sensing at least a portion of electromagnetic energy transmitted by the surface source loop and circuitry that converts analog signals sensed by the external two electrodes to digital signals; and a cable that operatively couples the tool to the surface equipment for transmission of the digital signals to the surface equipment for analysis.
