  • Publication number: 20250138266
    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.

  • Publication number: 20230407711
    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.

  • Patent number: 11725468
    Abstract: 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.

  • Patent number: 11668872
    Abstract: Sensors for imaging boreholes via the detection of electrical and optical properties may be subject to harsh conditions downhole, such as from pressure and temperature. In addition, these sensors may be subject to impact, such as tension, elongation, and compression forces, along the wall of the borehole. The harsh conditions downhole and impacts on the sensor can lead to premature wear and even breaking. The present disclosure generally relates to an apparatus for measuring electrical and optical properties of the borehole and methods for manufacturing the apparatus.

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.
