    Abstract: Methods and apparatus are provided for distributed temperature sensing along an optical waveguide disposed axially with respect to a conduit using a distributed temperature sensor and an array of temperature sensors. An exemplary method includes performing distributed temperature sensing (DTS) using two ends of a first optical fiber disposed within the conduit and having a return path coupling the two ends, performing discrete temperature sensing based on measured reflections of light from reflective elements having characteristic wavelengths disposed at discrete locations, and determining temperatures at a plurality of locations based on the DTS and the discrete temperature sensing.

    Abstract: Methods and apparatuses for obtaining information, such as location and/or identification information, regarding sensors in optical paths such as optical fibers. One embodiment provides a method for identifying a location of a tag in an optical path. The tag is (1) adapted for producing a response to an optical signal propagating along the optical path; and (2) responsive to a variation of a physical parameter to vary the response to the optical signal. The method comprises causing a variation of the physical parameter and identifying the location of the tag at least in part by observing the response of the tag to the optical signal. The tag may be associated with a sensor such that a location of the sensor may be derived based on the location of the tag.

    Abstract: A sensor arrangement using an optical fiber and methodologies for performing an analysis of a subterranean formation, such as a subterranean formation containing a hydrocarbon based fluid. The sensor arrangement may be used to measure one or more physical parameters, such as temperature and/or pressure, at a multiplicity of locations in the subterranean reservoir. The sensor arrangement may comprise a sensor array comprising an elongated outer casing for insertion in the subterranean formation and into a fluid in the subterranean formation. The sensor array may comprise an optical fiber defining an optical path that links one or more temperature sensors and one or more pressure sensors and transports measurement data generated by the temperature and pressure sensors. A data processing system may be connected to the sensor array to receive measurements from the sensor array and to compute one or more values of a property of an extraction installation operating on the subterranean formation.
