20170276894 · 2017-09-28 ·

Pipeline segments can contain cables, such as communication cables (e.g., fiber optic cables) within insulation material surrounding the pipeline segments. Cables can be embedded within the insulation material, run through conduits embedded within the insulation material, placed in channels formed in the insulation material, or otherwise. Channels containing one or more cables can be filled with supplemental insulation material, thus securing the cables within the channels. Pipelines created as disclosed herein can enable data transfer between distant points without the need to lay fiber optic cable in addition to the pipeline. Further, fiber optic cable embedded thusly can be used to sense conditions in the pipeline, such as leaks, seismic activity, strain, and temperature information.

DOWNHOLE FIBER INSTALLATION EQUIPMENT AND METHOD

Various embodiments include methods and apparatus structured to install an optical fiber cable into a well at a well site. In a from-bottom-to-top embodiment, an anchor deployed at a selected location in a hole of the well can be used and the optical fiber cable can be pulled up to a surface of the well from the selected location. In a from-top-to-bottom embodiment, an optical fiber cable can be moved down from the surface until an end of the optical fiber cable is locked at a selected location by a catcher disposed at the selected location. With the optical fiber cable in the well, a portion of the optical fiber cable can be coupled to surface instrumentation. Additional apparatus, systems, and methods can be implemented in a variety of applications.

FIBER CARRYING STRUCTURE INSTALLATION METHODS

Several methods of deploying an optical fiber carrying structure along a road are provided. In one method a recess and channel are created within a road. The optical fiber carrying structure is deployed in the channel and a cover encloses the optical fiber carrying structure within the channel. In another method the optical fiber carrying structure is anchored to the road and/or curb. In another method the optical fiber carrying structure is coupled to a brace that is affixed to the road. The brace facilitates quickly installing lateral transitions from the primary channel in the road to installation environments off the road.

LOGGING ENCAPSULATED OPTICAL-FIBER DUCT CABLE AND MANUFACTURING METHOD THEREOF

The present invention discloses a logging encapsulated optical-fiber duct cable and a manufacturing method thereof. The encapsulated optical-fiber duct cable mainly comprises an external encapsulation layer. At least one armor tube is arranged in the encapsulation layer. An optical fiber protective tube is arranged in each armor tube. A filling layer is arranged in a space between the optical fiber protective tube and the armor tube. An optical fiber is arranged in the optical fiber protective tube. The manufacturing method mainly comprises four steps: pavement of the optical fiber and formation of the protective tube, formation of the filling layer, formation of the armor tube and formation of the encapsulation layer. The optical-fiber duct cable of the present invention has the advantages of large length, high strength, good temperature tolerance, small signal transmission loss, high transmission speed and synchronous transmission of multiple signals.

Optical fibre deployment

A deployable device including a deployable member. The deployable member includes an optical fibre. The deployable member is stowed at the device in a first wound configuration and arranged to be deployed from the device to a second unwound configuration within a well. In examples, the deployable device is configured such that, when unwound, the deployable member has a propensity to adhere to a wall within the well. In examples, the deployable member includes at least a first length and second length, the first and second lengths having different mechanical properties.

ELECTRICALLY CONDUCTIVE FIBER OPTIC SLICKLINE FOR COILED TUBING OPERATIONS

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.

Containment system for sensing elements
