Abstract
A method and apparatus for installing an array of sensors in a wellbore wherein the sensors are incorporated into the lower end of a transmission cable which, in turn, is used to lower the array into the wellbore. A load-bearing cable is simultaneously run into the wellbore side-by-side with the transmission cable and the two cables are clamped together at spaced intervals whereby a substantial portion of the tensile forces in the transmission cable is transferred to the load-bearing cable.
