Well-logging system and method using an armored coaxial cable and compensation circuit
Patent
·
OSTI ID:7351207
The armored coaxial cable of a well-logging system has an inner conductor for sending electric pulses uphole and supplying high voltage downhole, a copper coaxial shield for providing a return path for the pulses and carrying low voltage downhole, and an outer armor serving as a common ground. A circuit at the surface compensates for the deterioration of the signal pulses during their transmission up the cable in accordance with the deterioration of monitored reference pulses that are generated in the logging instrument.
