A wellbore device and method for use in downhole operations are provided. The device may comprise a deployment member packaged in a first configuration arranged to be deployed from said first configuration upon deployment of the wellbore device within a wellbore. In some examples, a tool is also provided. The first disposable member may be made of a degradable material, and optionally may be a fibre optic for providing sensing and/or data communication. The tool may be a smart tool.

A method and apparatus for providing a fiber element are disclosed. The method includes the steps of opening a first control valve element (355) at a proximate end region of a first lumen (310) that extends along a flexible pipe (100), opening a first vent valve element (400) at a remote end region of a second lumen (320) that extends along the flexible pipe (100), providing a new fiber element along the second lumen (320) via an opening (350) at a proximate end region of the second lumen (320) and closing the first vent valve element (382) and the first control valve element (355).

A cable installation apparatus includes a drive assembly and a cable assembly, wherein the apparatus dispenses the cable onto and/or into and along the inner surface of a tubular structure while being moved. The apparatus also includes a securing assembly for holding and dispensing a securing material component while the apparatus is being moved along the length of the tubular structure, wherein the securing material component secures the cable to the inner surface of the tubular structure after being dispensed from the apparatus. A cleaning assembly may also be included for cleaning portions of the inner surface of the tubular structure while the apparatus is being moved along the length of the tubular structure and before the cable is dispensed onto and/or into the portions of the inner surface of the tubular structure.

The manifold is provided with a first cable passage at a first longitudinal position and a second cable passage at a second longitudinal position, wherein a releasable pipe segment is present between the first and the second longitudinal positions. It is suitable for use in a pipe, such as a pressure sewer. In use, a cable would be laid through the pipe with the manifold. Thereafter, the releasable pipe segment would be removed from neighboring pipe shells. The cable would be inserted into the cable passages, and a second pipe segment would replace the initial pipe segment.

Tubing encapsulated cable consists of one or more electrical conductors and possibly one or more fiber optic cables sheathed in a corrosion resistant metallic alloy. However, pumping during the installation of tubing encapsulated cable is required to overcome the capstan effect of the tubing encapsulate cable inside the coil tubing as the tubing encapsulated cable travels through the coiled up wraps of coil tubing. In an embodiment of the invention the tubing encapsulated cable consists of one or more electrical conductors and possibly one or more fiber optic cables sheathed in a fiber reinforced composite sheath. Because there is little drag between the fiber encapsulated cable and the coil tubing, conventional pumping operations used to install braided wireline into coil tubing may not be required when installing fiber encapsulated cable into coil tubing. Additionally, the smooth outside surface and relatively small diameter of the fiber encapsulated cable are desirable attributes for well intervention work because the smooth surface is more resistant to chemical attack than braided wire while the smooth surface and relatively small diameter provide little viscous drag while fluids are pumped through the coil tubing in the course of intervention operations.

A system includes a feedthrough cap having a guide funnel configured to extend about a tree body of a well system. The feedthrough cap includes a landing body configured to extend into the tree body and land on a hanger. The feedthrough cap includes a feedthrough line configured to extend through the feedthrough cap to the hanger.

A submarine device includes a main tail cable connected to a submarine cable, a first branch tail cable including a first group of optical fibers among a plurality of optical fibers included in the main tail cable, a second branch tail cable including a second group of optical fibers among the plurality of optical fibers, a branch member that couples the main tail cable to the first and second branch tail cables and including therein a through hole for branching the plurality of optical fibers included in the main tail cable into the first group and the second group, and a device main body including a first introduction part for introducing the first branch tail cable into the device main body and a second introduction part for introducing the second branch tail cable into the device main body. The branch member is fixed to the device main body.

A house connection for a cable in a medium conduit comprises a cable passage with which the cable is taken out of the medium conduit. The cable passage is provided with a cable tensioner with which a portion of the cable can be tensioned in the medium conduit. The cable passage is preferably part of a rotatable manifold.

A pipe section for coupling to one or more pipe sections in order to form an elongate tubular. The pipe section has an optical fiber extending along a longitudinal axis of the pipe section and a waveguide disposed near one end of the pipe section and is in optical communication with the optical fiber to guide light in a plane substantially perpendicular to the longitudinal axis.
