DTS Installed System Type The optical fiber is installed in a wellbore and attached to an instrument box. Calibrations are performed. In general, this should be a subelement of a DTS object. Is this a planned installation in a well, or has the installation already occurred. Note that the default value is 'false', which states that this is an actual installation. Information about the fiber used, and its installation. Information about the instrument box used, and its installation. The configuration of the fiber installation. Example values would be linear, linear with gauge, J, U. A fiber installed with a "U" configuration will have two ends available for hookup to an instrument box. In order to record which end is cabled to the instrument box on a particular measurement run, it is necessary to identify the two ends. This complex type allows a name and description for each end, so that it may be identified in a later use. This may also be useful when multiple fibers in multiple wellbores converge at the same wellhead. The length of the fiber installed in the wellbore. A table of values along the length along the fiber. Total light budget available for the installation. This is generally measured in decibels, and indicates the total power loss for two-way travel of the light in the installed fiber. The activity of pumping the fiber downhole This captures the data from the pre-installation and post-installation OTDR tests run on the fiber. A standard quality control program would include these two, but the schema allows for more than two if additional runs associated with the installation of the fiber are performed. OTDR runs associated with a measurement are given as a child of the measurementInformation element. Any calibration other than the ones explicitly given may be recorded here. This is a general calibration type, which is populated with name/value pairs. If an instrument box is changed, for example, but the fiber remains the same, this instance of installed fiber is given to record that change. This element refers to a previous installed fiber, on which this one is based. For example, the wellboreFiberSchematic is unchanged, and may be obtained from the previous instance of installed fiber that is referenced here.
