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 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.

Abstract: An opto-electrical cable may include an opto-electrical cable core and a polymer layer surrounding the opto-electrical cable core. The opto-electrical cable core may include a wire, one or more channels extending longitudinally along the wire, and one or more optical fibers extending within each channel. The opto-electrical cable may be made by a method that includes providing a wire having a channel, providing optical fibers within the channel to form an opto-electrical cable core, and applying a polymer layer around the opto-electrical cable core. A multi-component cable may include one or more electrical conductor cables and one or more opto-electrical cables arranged in a coax, triad, quad configuration, or hepta configuration. Deformable polymer may surround the opto-electrical cables and electrical conductor cables.

Abstract: A fiber optic thread assembly configured with a cumulative gap for mechanical responsiveness and protection from micro-bend damage. The assembly may be incorporated into a wireline or slickline cable for obtaining fiber optic readings of enhanced accuracy during an application in a well. The gap is uniquely tailored to allow for a natural reduction during deployment of the cable into the well, thereby providing the enhanced accuracy. However, the gap is also sufficient to help avoid micro-bend damage from the resulting mechanical responsiveness, which is attained upon deployment of the cable into the well.

Abstract: A slickline that includes both electrically conductive and fiber optic capacity. The slickline includes a fiber optic thread or bundle of threads that may be surrounded by an electrically conductive member such as split half shells of copper elements. Further, these features may be disposed in a filler matrix so as to provide a cohesiveness the core of the slickline. So, for example, the line may be more effectively utilized in downhole applications such as coiled tubing operations, without undue concern over collapse or pinhole issues emerging in the line.

Abstract: Cables that include a conductor and an optical fiber. In some embodiments, the cable can include an optical fiber loosely disposed within an enclosure. A conductor layer can be disposed about the enclosure. An insulation layer can be disposed about the at least one conductor layer. An inner layer of armor strength members can be helically disposed about the insulation layer. An outer layer of armor strength members can be helically disposed about the inner layer of armor strength members. The armor strength members in the outer layer of armor strength members can be at an opposite helix compared to the armor strength members in the inner layer of armor strength members. An outer jacket can be disposed about the outer layer. In other embodiments, the cable can include an optical fiber in a coupled electro-optical package, where the conductor layer can be disposed about the electro-optical package.
