PR000-22605-R04 Methods to Reduce the Threshold of Detection of Identifying Leaks

In pipeline systems, whether gas or liquid, achieving a perfect balance between inbound and outbound volume, mass, or energy is unattainable due to measurement uncertainties, operational noise, and accounting errors. This report introduces advanced analytic methods which aid in getting closer to the ‘perfect balance’ by identifying specific meters contributing to balance discrepancies and by improving the accuracy of estimating the inventory of the product in the pipeline.

By reducing measurement uncertainty, operators can enhance leak detection sensitivity and pinpoint where efforts should be focused to address specific measurement problems.

The methods developed in this effort have been validated using double-blind simulated data and tested against a real dataset. Enhancements to reduce measurement uncertainty allow lost and unaccounted methods to reliably identify leaks, theft, and other unexpected or unaccounted-for product loss. These methods also support the ability to find smaller leaks using online leak detection systems.

The target audience for this document is Measurement technicians, Measurement specialists, Measurement accountants, and Leak detection experts.

This document also makes a good primer for individuals that are new to product measurement in the pipeline industry.
