Abstract Summary 

Invention of the Distributed Fiber Optical Sensing (DFOS) was a great scientific achievement, which offered countless possibilities for industrial use and deployment in real-world applications. Creating an industrial level DFOS required, however, a substantial engineering development in many areas, from design to manufacturing. We were fortunate to be involved from the early stage of scientific research and then the very start of DFOS as an industry. DFOS creates the value chain, referred to here as ‘rings’, which is composed of glass, coat and over-coating, cable, interrogator, integrated system, field installation, data acquisition and visualization, as well as communication with user expertise to create the value. The ‘chain’ here means that these elements are all linked together, and the connections are not allowed to break. Over the years we’ve been building the chain and its rings which are meeting the engineering and industrial requirements. We will describe recent progress in key areas and development of new products: PSP-BOTDR, a single end high spatial resolution and high precision instrument, without drift and deterioration over long distance, and TGD-OFDR, the DAS capable interrogator capable of performing real time phase acquisition with superior SNR and noise floor. We will present case studies demonstrating achieved results. Both developed methods add value to temperature (DTS), Rayleigh and Brillouin temperature and strain (DTSS) and their hybrid versions. The good news is, we have surpassed our expectations of Fiber Optics and we will be able to meet the industry's requirements for engineers.

Kinzo Kishida is the founder and CEO of Neubrex Co. Ltd., Japan. He holds PhD degree from Osaka University, Japan. His fields of expertise are shock waves in condensed materials, dynamic brittle fracture mechanics, and especially distributed optical fiber sensing, which he has been working since 1997 on. Before founding Neubrex in 2002, he worked for Advanced Research and Development Institute of Mitsubishi Electric Corporation, Japan. Dr Kishida acquired over 50 international patents in all aspects of distributed optical fiber sensing, including high (cm-order) spatial resolution Brillouin and Rayleigh scattering strain and temperature systems, hybrid and chemical sensing, and the invention and design of distributed pressure, acoustic, temperature, and strain (DPATS) cable, which exposes optical fiber directly to fluids in downhole environment.
