Fiber Optic Cable Dedicated 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 monitoring systems help. Paper presented at the SPE Conference at Oman Petroleum & Energy Show, Muscat, Oman, May 2026. For real-time reservoir surveillance without interrupting well, Fiber-Optic (FO) cable has been deployed behind production casing. However, execution is challenging, particularly with respect to deploying. FOWell, a distributed fiber optic sensing well monitoring solution, enables for real-time detection of leaks or deformations in the tubing or casing structure. Facilitating the quick implementation of solutions, it minimizes the environmental and production impact of well issues. The optical fibers can be used to sense. Unfortunately, EGS reservoirs, dominated by high temperatures and corrosive brines, are a hostile environment for classical point sensors most useful in these monitoring tasks; seismic sensors in particular have a poor track record during intermediate and long duration studies in geothermal. Aspects of the subject technology relate to systems and methods for deploying fiber optic lines in a wellbore using a fiber optic deployment device.
