Abstract
One of the most challenging problems in geothermal logging is to develop a cablehead that interconnects the wire line cable to other downhole instrument such that the system will successfully operate in a geothermal well. A high temperature (275°C), corrosion resistant logging cablehead for use with single conductor cables is described. The head has demonstrated the ability to solve electrical communications problems (leakage resistance) generally associated with the cable-to-sonde interface while logging hostile environment geothermal wells.
