Abstract: Due to the complexity and continuously evolving nature of gathering pipelines in the upstream oil and gas industry, reliable and timely leak detection can be difficult to achieve. Many times wells are being retired while new wells are coming online meaning the pipeline network to be monitored for leaks is continuously changing. To utilize the optimum solution for leak detection, Real Time Transient Modelling (RTTM) extended with leak signature analysis (E-RTTM), as is used by the vast majority of Midstream Companies, excessively high costs for re-modelling and re-tuning would be necessary. The cost to maintain such a system on Gathering Lines is not justified and as a result, most of these complex piping networks rely on the simplest form of leak detection, basic volume or mass balance.
