Wireline plugs for use in a Y-tool. In some embodiments, the wireline plug can include an elongated body defining a bore therethrough. A first end of the elongated body can include an outer surface configured to serve as a fishing neck and a second end configured to connect to a downhole tool. The wireline plug can include an elongated seal defining a bore therethrough disposed within a portion of the bore defined by the elongated body. The elongated seal can be configured to provide an at least partial fluid seal between an inner surface of the bore defined by the elongated body and an outer surface of a wireline when disposed within the bore defined by the elongated seal. The elongated seal can be formed from a polymer, an elastomer, or a combination of a polymer and an elastomer.

Wireline plugs for use in a Y-tool

A fiber optic bundle for incorporation into a cable for use in a well. The bundle includes multiple fiber optic threads that are helically wound about one another at a zero degree lay angle for structural reinforcement. Further, the cable that employs the bundle may be coupled in nature and gas proof thereby rendering the fiber optics mechanically responsive for improved accuracy in detections during use in a well application.

Stranded fiber-optic cable

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.

Electrically conductive fiber optic slickline for coiled tubing operations

Anchor assemblies for use on a downhole cable and processes for using same. In some embodiments, the anchor assembly can include a first anchor configured to be releasably connected to a second anchor. The first anchor can define a bore therethrough that can be configured to receive and permit a cable to move therethrough such that the cable can be connected to the second anchor. The second anchor can include one or more switchable magnets each configured to switch between a non-magnetized state and a magnetized state. When the anchor assembly is located within a downhole casing and the one or more switchable magnets are switched from the non-magnetized state to the magnetized state, the one or more switchable magnets can be configured to secure the second anchor to an inner surface of the downhole casing.

Anchor assemblies for use on a cable and processes for using same

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.

Electro-optical wireline cables

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.

Mechanically responsive fiber optic thread assembly

A wireline cable includes an electrically conductive cable core for transmitting electrical power. The wireline cable further includes an inner layer of a plurality of first armor wires surrounding the cable core and an outer layer of a plurality of second armor wires surrounding the inner layer, wherein a diameter of the outer layer of the plurality of second armor wires is smaller than a diameter of the inner layer of the plurality of first armor wires.

Reduced torque wireline cable

Various cables for cable deployed electric submersible pumping systems and methods of manufacturing such cables are provided. The cable includes a power cable core and coiled tubing formed around the power cable core. The power cable core includes one or more conductors, insulation surrounding each conductor, and an elastomeric jacket extruded around the insulated conductors. Various mechanisms, systems, and methods are described to anchor the power cable core in the coiled tubing and to transfer weight from the power cable core to the coiled tubing.

Cables for cable deployed electric submersible pumps

Electrical cables and processes for making and using same. In some examples, the electrical cable can include one or more insulated electrical conductors and one or more metallic elements cabled together and a metallic layer disposed about the one or more insulated electrical conductors and the one or more metallic elements. The one or more metallic elements can partially fill a space located between the one or more insulated electrical conductors and the metallic layer. The one or more insulated electrical conductors can each include an electrically conductive core, a layer of electrically insulating material disposed about the electrically conductive core, and a layer of metallic strands disposed about the layer of electrically insulating material.

Processes for making electrical cables

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.

Compression and stretch resistant components and cables for oilfield applications

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.

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.
