ABSTRACT An improved apparatus to store an insulated electrical conductor cable in a overlapped configuration within a drill pipe includes a track attached to the drill pipe to guide a lower cable guide so that the over- lapped portions of conductor cable will not snarl or twist during rotary drilling operations. To insure against entanglement, further restriction of rotation may be gained by additionally tracking the lower cable guide on a tensioned portion of the conductor cable which extends from a subsurface instrument package upwardly to an upper cable guide. A method for installing this improved apparatus is also disclosed. -19-
