Home / Principle of Thailand s Single-Mode Well Logging Optical Cable

These monitoring systems help improve well productivity by identifying trends throughout the producing life of the well, and they rely on the robust design and long-term survivability of optical cables under harsh downhole conditions. Since the optical fibres act as the sensor array the system is inherently reliable and so ofers a more cost efective means to gathe e cable it is possible to introduce one to the wellbore as an intervention. More time and cost effective deployment is possible, but continued research and development efforts are necessary to. Permanent downhole fiber-optic cables are critical infrastructure in wellbore monitoring systems, ensuring reliable transmission of data for applications such as distributed temperature, acoustic, and strain sensing (DTS, DAS, and DSS)—all with one 1/4-in control line. Paper presented at the SPE/ICoTA Well Intervention Conference and Exhibition, The Woodlands, Texas, USA, March 2020. This study presents the evolution of downhole fiber optics to a new hybrid electro-optical cable for coiled tubing (CT) applications. The network is composed of a ground-based sensing signal demodulation system, a fault detection module, and an underground optical fiber sensing topology.
