A cable core including a body, a recess in the body, and a protrusion extending radially outwardly from the body and along the recess. A cladding disposed radially outwardly of the core is used to create a cable.

Conductor cable and method

A method for deploying a fiber optic line from a surface to a desired location in a wellbore includes the steps of identifying a heater cable deployed in the wellbore, where the heater cable includes one or more conductors and a first capillary tube. The method continues with the step of loading a terminal end of the fiber optic line into the first capillary tube from the surface. Next, the method includes the step of pumping a working fluid into the first capillary tube from the surface to inject the fiber optic line through a portion of the first capillary tube. The method concludes with the step of stopping the injection of the fiber optic line when the terminal end of the fiber optic line reaches the desired location in the wellbore.

Heater cable with injectable fiber optics

A sensing apparatus includes a sheath, a central member disposed in the sheath, at least one optical fiber disposed with the central member, and a film adhesive disposed between the central member and the sheath, the film adhesive provided in one or more sheets or strips and disposed in one or more layers between the central member and the sheath, and the film adhesive attached to the sheath.

A fiber support arrangement for a downhole tool includes at least one tubular and at least one bracket positioning the at least one tubular spaced radially from a downhole tool and lacking contact therewith. At least two fibers are supported at the at least one tubular with at least two of the at least two fibers having a different helical angle from one another relative to an axis of the downhole tool.

Fiber support arrangement and method

A method for estimating a shape, the method including: selecting a structure comprising a plurality of strain sensors inoperable communication with the structure, each strain sensor configured to provide a strain measurement; placing the structure in a borehole; receiving the strain measurements from the plurality of strain sensors; creating a mesh grid having nodes, each node related to a location of one strain sensor and assigned a strain value measured by the one strain sensor; creating an additional node for the mesh grid wherein a strain value assigned to the additional node is derived from the strain value corresponding to at least one adjacent node; and performing an inverse finite method using the mesh grid with the assigned strain values to estimate the shape.

Method for analyzing strain data

Disclosed herein is a carrier for an optical fiber having a plurality of optical sensors located thereon. The carrier has a test section comprising a cavity and at least one geometric discontinuity, wherein in response to a pressure applied to the test section, a stress concentration is formed proximate to the geometric discontinuity, and wherein the optical sensor is adhered to at least a part of the geometric discontinuity. The cavity may be filled with a liquid or a gel. A temperature optical sensor may also be provided adjacent to the pressure optical sensor.

Distributed optical pressure and temperature sensors

A method for making a cable includes creating a curvature in a conduit; pumping one or more fibers into the conduit; and securing at least one of the one or more fibers to a shortest pathway within the conduit and cable.

Cable and method

The well condition during gravel packing is monitored and the gravel distribution condition is sent to the surface in real time through the preferred technique of a fiber optic line that wraps around the screens directly or indirectly on a surrounding tube around the screens. The fiber optic line has a breakaway connection that severs when the completion inner string is removed. A production string can then be run in to tag the fiber optic line through a wet connect to continue monitoring well conditions in the production phase. The fiber optic line can also be coiled above the packer so that relative movement of the inner string to the set packer can be detected and communicated to the surface in real time so as to know that the crossover has been moved the proper distance to, for example, get it from the gravel packing position to the reverse out position.
