Abstract: The present invention relates to methods of manufacturing tapeless cable assemblies. The methods generally include providing a plurality of adjacent conductor cables, followed by applying a cross-linkable first material around the plurality of conductor cables and in the interstitial openings occurring between the cables. Cross-linking can be initiated by applying a second material which facilitates cross-linking of the first material or by other means such as exposing the material to ultraviolet radiation. The wrapped assembly is then welded to form a core assembly. The disclosed manufacturing methods do no require a tape, thereby shortening the manufacturing process and reducing the manufacturing costs.

The connector comprises a first part with N engagement members; a second part with N+1 engagement members; and a sleeve having a first and second end, the first end having N engagement members for engaging the N engagement members of the first part, the second end having N+1 engagement members for engaging the N+1 engagement members of the second end.

Abstract: A hydrocarbon monitoring cable including resistance to development of defects in a fiber optic core thereof. The core defect resistance may be in the form of resistance to defect causing agents of a downhole environment such as hydrogen. This may be obtained through the use of a carbon layer about the fiber optic core. However, in light of the differing coefficients of thermal expansion between such a carbon layer and an outer polymer jacket, an intermediate polymer layer of a third coefficient of thermal expansion may be disposed between the carbon and jacket layers. Thus, the intermediate polymer layer may be of a third coefficient of thermal expansion selected so as to avoid fiber optic defect causing thermal expansion from the downhole environment itself. Additionally, the monitoring cable may include an electrically conductive layer about the fiber optic core that is positively charged to repel other positively charged fiber optic defect causing agents of the downhole environment.
