Paper Number: SPE-187417-MS
... Abstract Early detection of subsea pipeline leaks is a very serious, and still continuing, issue for the oil and gas industry with limited successful cases reported. For example, aerial surveillance of pipeline can only be applied for relatively shallow and concentrated areas, and an advanced...

Paper Number: SPE-181455-MS
... Abstract Well integrity is becoming a key area of focus for most operators during the entire well life cycle. Acoustic conformance-monitoring systems have been developed to detect undesired leaks in terms of depth and radial location and to estimate leak flow rates, enabling operators to assess...

Paper Number: SPE-181497-MS
... Abstract This paper presents a new technology and methods that can detect leak locations in a well and illustrate the flow profile of the leak. A substantial amount of time and effort can be used toward repairing leaks in wells, and these methods and technology can reduce that time. The paper...
