Abstract: A downhole cable that has a cable core with an inner jacket located about it. The inner jacket has a shell located thereabout, and a pair of strength member layers surrounds the inner shell. Interstitial spaces of the strength member layers are filled with bonding layers. One of the strength member layers is at a contra-helical lay angle to the other. An outer jacket is located about one of the strength member layers, and the outer jacket is bonded with the bonding layers.

Abstract: A dual use cable includes at least one fiber optic cable encased in a metallic component that is encased in a layer of polymer material. The polymer material is surrounded by a tube or armor wire strength members embedded in one or two additional polymer material layers. A final assembly can include an outer metallic component or an outer layer of polymer material. The at least one fiber optic cable transmits data and the armor wire strength members and/or metallic components transmit at least one of electrical power and data.

Abstract: A technique for manufacturing slickline with a jacket of enhanced bonding. The technique may include roughening an outer surface of a metal core and applying an initial insulating polymer layer to the roughened core in a non-compression manner such as by tubing extrusion. The insulated core may then be heated and run through a set of shaping rollers. Thus, the grip between the polymer and the underlying metal core may be enhanced at a time following the initial placement of the polymer on the core. In this manner, processing damage to the underlying core surface which might adversely affect maintaining the grip may be minimized. Other techniques such as powder spray delivery of the initial polymer layer may also be utilized in a similar manner.

Abstract: A system includes a cable and a toolstring. The toolstring may couple to the cable to enable the toolstring to be placed in a wellbore. The toolstring includes a sensor that can collect measurements relating to the wellbore. An electromagnetic or anchoring device may selectively hold the toolstring or the cable against a surface of the wellbore.
