Fiber optic technology offers a robust, passive alternative that survives these harsh conditions for decades. 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. These fibers are most commonly made of glass and are very thin, typically less than a tenth of the width of a human hair. Fiber optic cable. FOWell, a distributed fiber optic sensing well monitoring solution, enables for real-time detection of leaks or deformations in the tubing or casing structure. It's simply the best way to deploy optical fibre for distributed sensing in a static. ExpressFiber disposable fiber cable is the newest addition to our scalable fiber portfolio that provides a direct measurement of well interference—at a price point comparable to tracers and indirect pressure analysis. ExpressFiber is run in offset wells to acquire direct measurements of distributed.
