14.3.1 Fiber Optical Path

For StandardPRODML v2.0

An optical path is a set of continuous optical waveguides that acts as a linear sensor, used to record temperature or acoustic or dynamic strain events along its length, as shown for example in Figure 14.3.1-1 . It can be composed of one or more optical path components and has one termination. An optical path component could be a fiber segment, a connector, a splice, or a turnaround. See Section 16.3 Installation in Wellbores for some example physical fiber installations in wellbores which may make up the Optical Path.

In the PRODML distributed data objects, the optical path is represented by a Fiber Optical Path top-level object. This object contains one optical path object that represents both the collection of components used along the path and the connection network.

Figure 14.3.1-1 Example of a dual-ended optical path installation, showing different types of components.

In this example, we have one optical path that is deployed in a well in a dual-ended configuration.

To support the requirement to be able to track the changes in the path over time, the optical path is represented using the inventory and network pattern explained in the following sections.
