ABSTRACT:
A slick-line coax cable for use in downhole well-logging under conditions which would normally prevent logging with standard `stranded` line cables includes a device for preventing migration of fluid inside the cable, a coaxial conductive layer of metal to allow more efficient data transfer from the downhole logging tools to the surface recording equipment, and a seal for terminating the downhole end of the metal-encapsulated cable thereby preventing downhole pressure and fluid migration into the cable.
