Global distributed acoustic sensing market (DAS) is estimated to grow from USD 462 million in 2020 to USD 792 million by 2025; it is expected to grow at a Compound Annual Growth Rate (CAGR) of 11.4% during 2020–2025.


APAC is one of the fastest-growing markets for DAS solutions, with China dominating the DAS market in the region with its increasing oil production operations and the development of military and infrastructure. With huge investments in developing infrastructure in the fast-growing developing nations such as China and India in the region, the market presents a huge potential for the implementation of DAS systems.


The development of military strength in the region has also increased the potential for the deployment of DAS technology. The diffusion of knowledge about the benefits of DAS technology such as lower operating costs and less maintenance in the region is critical for the growth of the technology in the region. Hence, the market is APAC is forecasted to witness the highest growth due to the construction and expansion of oil & gas pipelines and increased foreign investments in the development of oilfields.

In the oil & gas industry, well monitoring using DAS systems provide significant benefits in optimizing and maximizing the production of both offshore and inland oilfields. The industry is one of the primary users of DAS systems, with several oil & gas companies such as Schlumberger (US) and Halliburton (US) having a significant investment in the technology. New pipeline projects are also being deployed worldwide on a large scale and DAS technology has proven ideal and cost effective for long-distance monitoring.


The visualization software is often specific to the DAS application. The software often shows the path of the optic fiber cable routing against a site map and will highlight the location where an event is taking place (for instance, a leak in an oil pipeline). For perimeter security, the DAS software is often interfaced with existing third-party SCADA control or security software, which highlights an event.


Single-mode fibers are intended for long haul communications and therefore, are preferred for most DAS applications. Telecommunications-grade single-mode fiber optic cables can support distances of 50 km without any perceived noise in the signal. Hence, most DAS applications such as pipeline monitoring or border/perimeter surveillance generally utilize single-mode fibers since they provide a higher range of about 50 km. This makes the systems much more cost efficient as the interrogator units have to be deployed at every 50 km. Since single-mode fibers are sufficient for the majority applications, they are expected to hold a larger share of the market throughout the forecast period compared to multimode fibers.
