Accelerating Pipeline Leak Detection Quantification Solutions Through Transparent and Rigorous Scientific Validation

Overview

Main Objective

The project will—

• Investigate and document existing technology service provider leak detection and quantification (LDAQ) methodologies and their applicability to complex pipeline environments.
• Conduct comprehensive, multi-solution, controlled field testing, including testing multiple pipeline types (e.g., flow and gathering lines), complex environments (e.g., aerodynamics, topology, and accessibility) and varying operating conditions.
• Deliver an empirical analysis of LDAQ protocol enhancements that can: 1) be realistically incorporated into operator and service provider leak detection protocols, and 2) aid developers in LDAQ solution development.

Public Abstract

Project Description and Anticipated Results: This project addresses PHMSA's request for improvements in pipeline leak detection in diverse operating conditions by developing methods-centric rather than technology–specific understanding of leak detection in adverse conditions, with an emphasis on pipeline emissions in rugged landscape. This work will 1. Investigate existing private and public service providers' and operators' LDAQ methods and their applicability to complex pipeline environments, 2. Recommend enhancements to overcome shortcomings to existing approaches, 3. Conduct comprehensive, multi-solution controlled and field testing, including testing multiple pipeline types (e.g. flow and gathering lines), complex environments (including aerodynamics, topology, and accessibility) and varying operating conditions, 4. Deliver empirical analysis of enhancements to LDAQ protocols that can be realistically incorporated into operator leak detection protocols and aid developers in LDAQ solution development. Major scope items for investigation include protocol enhancements, controlled testing and field trials, and methods performance simulation using robust test data sets. Colorado State University (CSU) and the University of Texas at Arlington (UTA) will collaborate with industry and solution providers, who will be members on a technical advisory panel, provide access to their LDAQ protocols, and, in some cases, participate in field testing. Testing will be conducted at CSU's Methane Emission Technology Evaluation Center (METEC), on public land in collaboration with the US Forest Service and US Dept of Agriculture, and at service provider/operator test facilities.

Potential Impact on Safety: LDAQ solution enhancements, validated through measurement and quantitative analysis are directly beneficial to the NG industry and PHMSA's mission to find solutions to pipeline operational safety, reliability, and environmental challenges.
