Principle: Based on Rayleigh scattering to capture acoustic signals along the wellbore. Application: DAS is used to detect and locate leaks, monitor cement integrity, and identify mechanical issues within the well. 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 include several distributed methods, where data is recorded with high spatial and temporal resolution over long distances using the optical fiber as a sensor, exploiting different scattering mechanisms.
Logging steps: Baseline, bleedoff, buildup well integrity issues are some of the practical application scenarios for DTS/DAS fiber-optic well integrity diagnosis.
Specifically, we highlight the diagnostic power of distributed temperature sensing (DTS) and distributed acoustic sensing (DAS) in two real-world field applications. In each case, traditional tools failed to
