“…Moreover, fiber optic‐based leak detection include two types of systems on basis of their design: discrete and distributed. The discrete system mainly uses a single fiber optic sensor focuses on collecting point data from a single point at a time (Li et al, 2021). In contrast, the distributed system consists of multiple sensors which can make multiple measurements simultaneously (Muanenda et al, 2019).…”

Effective water pipeline leak detection and localization can help water practitioners save water losses and reduce pipe rehabilitation budgets. Different sensing technologies can provide essential data aiding model development for predicting future leaks in the water distribution networks. Solutions for applying different sensing technologies to real water distribution networks are being developed for real‐time data collection, precise leak localization, reducing false alarms, and continuous pipeline monitoring. Experiments of different scales and specifications have been conducted to test the application and effectiveness of sensing technologies for leak diagnosis in water pipelines. Quality data collection is especially crucial for the successful implementation of these experiments. However, practitioners need help designing effective leak detection and localization experiments, wasting time, and resources. There needs to be a greater understanding of the design parameters for more accurate testing, such as sensor selection, sensor placement, ambient noise sources, and system operations. The current study, therefore, delineates design parameters for design leak diagnosis experiments for lab, testbed, and real networks. For application in real water networks, expert opinion is used to help identify the benefits and limitations and the implementation issues of available sensing technologies. An example experiment design using multi‐sensing technologies for smart leak diagnostics in Hong Kong is also presented. The study can guide water practitioners and researchers to design a multi‐sensing leak diagnostic experiments enabling a smart and sustainable utility management.This article is categorized under: Engineering Water > Methods Engineering Water > Sustainable Engineering of Water Science of Water > Water Extremes

“…On the basis of the monitoring scheme, the fiber-optic sensors can be classified as discrete and distributed. A discrete scheme allows measurement at a single point and mainly uses fiber Bragg grating as the sensing material whose center wavelength changes with temperature or strain variation (Li et al 2021). A number of fiber Bragg gratings are inscribed on various distances over the same fiber for long-distance sensing.…”

“…The literature review revealed that most of the studies adopted distributed optical fibre sensors (DOFS) sensing mechanism for leak detection and localization (Nikles et al 2004;Li et al 2021;Yao et al 2021). Research demonstrating other available fiber optics sensing systems for leak detection is limited and their potential of higher efficiency and cost-effectiveness is less explored.…”

This study reviews the state-of-the-art application of fiber optics in water distribution networks for leak detection and localization. The use of fiber optics in the oil and gas sector has been well-established; however, its potential in water pipelines is not evident owing to limited research. This study, therefore, presents the research developments of fiber optics in water leak detection and localization using the mixed methodology approach by integrating bibliometric and systematic analyses. A scientometric analysis is carried out to analyze the science maps of (1) journal sources, (2) contributing countries, and (3) co-occurrence of influential keywords. The systematic analysis evaluates the use of eight types of fiber optics, such as accelerometer-based fiber optics and hydrophone-based fiber optics, in water leak detection and localization. The review reveals five important directions for future research such as real network-based studies and the development of hybrid techniques.

“…Therefore, they can detect large leakage hole or deformation, but not all types of leakage points. Besides the above engineering logging techniques, distributed fiber acoustic sensing (DAS) 42,43 and distributed fiber temperature sensing (DTS) 44 can also measure the leakage noise and temperature difference, but the fiber cannot reach a depth over 4500 m due to limited tensile strength. Therefore, it is not suitable for the leakage measurement in high‐pressure well, because the high‐pressure well is usually over 5000 m depth 45–47 …”

Leakage is one of the most serious challenges for the safe production of high‐pressure gas wells for its high risks, including abnormal annular pressure, natural gas accumulation, and environment pollution, but available methods can hardly accurately measure the leakage type and depth, which are the key parameters for the rigless leakage repair and risk assessment. Therefore, this paper proposes a method to measure the leakage based on the characteristics, which combines qualitative and quantitative measurement together. Qualitative measurement considers the annular pressure, tubing pressure, liquid level, cement quality, and workover history. Quantitative measurement is determined by noise logging, electromagnetic logging, pressure logging, and temperature logging. The logging should be optimized according to the qualitative measurement. The method was successfully applied in high‐pressure gas well belonging to Tarim Oilfield. Two potential leakage types are provided based on the annular pressure, liquid level, cement quality, and workover history, including tubing leakage and linger hanger leakage. Based on the potential leakage types, the pressure difference, logging devices string, stopping length, and time are optimized to make the engineering logging reliable. Through measurement, two leakage points are found in tubing string. One is tubing body crack at the depth of 2724 m and the other is tubing thread leakage at the depth of 5211.7 m, which well matches the production data.
