ABSTRACT The Negative Pressure Wave (NPW) leak detection method has been increasing in popularity recently due to the promise of highly accurate leak location...

... to demonstrate the potential way of using machine learning and artificial intelligence in pipeline data analysis and operation analysis. artificial intelligence nnet package upstream oil & gas relative roughness neural network detection diameter neuron flow rate hydraulic model machine...

... Abstract For many years, the pipeline industry has worked on leak detection technologies to accurately predict and mitigate the occurrence of leaks in pipelines. However, this is not an easy task since many systems have different characteristics and the existing technologies have specific...

... Abstract In the recent decades, new leak detection technologies for hydrocarbon pipelines are emerging constantly, and conventional technologies are evolving to achieve better performance. It gives pipeline operators a good chance to detect leaks in the early phase and protect the environment...

... in controlling and detecting the loss of product under these circumstances and steps that can be done to detect these small leaks. The discussion will detail a technique that can be applied to an existing real time transient model leak detection system that will allow for accurate modeling of theft detection...

... ABSTRACT LDS, detecting pressure drop surge seem to be the most effective for the leak detection in pipelines. In fact, such systems have very high sensitivity. Despite that there are false leak detections, when disturbances in the pipeline are not related to leakage (such disturbances might...

... ABSTRACT As pipeline leak detection systems become more widely deployed in the oil, gas, chemical and water industry, the demand for performance improvement increases rapidly. This paper describes the following leak detection technologies and their applicability to different pipelines: Real...

... ABSTRACT Computational monitoring systems are often the first line of defense in terms of detecting leaks from cross country pipelines. However, the alarms provided by these systems often require considerable review, assessment and analysis by pipeline control, operations and engineering...

... models are one of the most useful applications made by the pipeline simulation industry. They have many different functions including detection of leaks and other anomalies like failing equipment, describing what is happening in the line at unintsrumented locations, and maintaining an accurate picture...

... ABSTRACT Leak detection is critical to the safety of the environment and of increasing importance to those responsible and accountable for pipeline operations. The ability to detect and locate leaks in tight-line operation has been understood and advanced for quite some time. Slack-line leak...

... detection of such leaks are suggested. The paper documents real cases of product theft which appeared on 10"-12" pipelines, its reflection in pressure and flow trends, and the response of the leak detection system. The paper analyses the requirements put on all involved elements of technology from...

... ABSTRACT Present-day systems for modeling and control of gas transport and distribution commonly offer the Leak Detection and Leak Localization as one of their features. The function is usually based on running comparison of calculated and measured values. Sensitivity of Leak Detection...

... ABSTRACT In the present article the problem of detection of leaks, which are created artificially in pipelines is examined. There were analyzed various methods of petroleum collection from a pipeline and how mechanisms of it influence the efficiency of various leak detection algorithms. Here...
