Principle of Photonic Crystal Fiber Optic Sensors
Photonic crystal fibers (PCFs) are a special class of optical fibers with a periodic arrangement of microstructured holes located in the fiber's cladding. Light confinement is achieved by means of either index-guiding, or the photonic bandgap effect in a low-index core. The different strategies successfully applied in order to obtain feasible and reliable monitoring systems in several application fields, including medicine, biology, environment.

Where are the fiber optic sensors on Indonesian drilling rigs
The hybrid fiber optic cable is embedded inside the wireline cable, and hence VSP survey can now be acquired with any wireline run, making it transparent to rig hours. The new technology for acquiring Vertical Seismic Profiling (VSP) survey using a distributed acoustic sensing (DAS) measurement is very beneficial in reducing the time and cost of operations and increasing the value of VSP surveys. The hybrid fiber optic cable is embedded inside the wireline cable. This paper presents a comprehensive technical evaluation of Mubadala Energy's deepwater exploration campaign in the Offshore Andaman Basin, Indonesia, where an integrated suite of Logging While Drilling (LWD), Seismic While Drilling (SWD), and fiber-optic Distributed Acoustic Sensing (DAS). Distributed fiber optic sensing (DFOS) leverages the scattering of light within an optical fiber to monitor physical changes along its length. It relies primarily on three types of backscattering phenomena: Rayleigh scattering (used in DAS) ā sensitive to micro-vibrations and pressure-induced. In short, fiber optics provide a safer, faster, and more reliable backbone for modern oil and gas infrastructure.
