Abstract

See full text

A slickline that includes both electrically conductive and fiber optic capacity. The slickline includes a fiber optic thread or bundle of threads disposed in a support tube and surrounded by an electrically conductive member such as tightly wound copper threads. In certain embodiments, the electrically conductive member may be provided in direct contact with the support tube without the requirement of an insulating layer. Alternatively, the tube itself may be foregone with a channel for the fiber optic thread or bundle defined by insulating material about the electrically conductive member. Either way, the overall profile of the slickline may advantageously be kept to a minimum.
