Methane quantification performance of the quantitative optical gas imaging system using single-blind controlled release assessment
This study assessed the quantification performance of the FLIR QL320 Quantitative Optical Gas Imaging (QOGI) system for detecting methane leaks. Conducted in a controlled outdoor setting, the study included 357 measurements from 26 controlled releases of compressed natural gas. Results showed that 75% of measurements were within a quantification factor of 3, though quantification errors […]
Detection limits of optical gas imaging for natural gas leak detection in realistic controlled conditions
A study aimed to characterize the detection efficacy of Optical Gas Imaging (OGI) in finding leaks at natural gas facilities. The study revealed that surveyor experience and survey protocols significantly impact leak detection rates, with experienced surveyors detecting substantially more leaks than less experienced ones.
Comparing continuous methane monitoring technologies for high-volume emissions: A single-blind controlled release study
This study assessed eight commercial monitoring solutions, revealing varying performance in detection and quantification, with some systems underestimating emissions by 74%. While true positive rates were generally high, reliability varied, indicating that more research is needed to understand the strengths and weaknesses of these systems before broader adoption in regulatory frameworks.
Assessing the progress of the performance of continuous monitoring solutions under a single-blind controlled testing protocol
Study evaluating the performance of nine continuous monitoring (CM) solutions for methane emissions through controlled testing. Over 11 weeks, tests involved controlled releases of methane under varying conditions. There were significant uncertainties in emission quantification, with some solutions showing large underestimations and overestimations. The results underscore the importance of regular quality testing for advancing CM […]
Alternative methane detection technologies evaluation – alternative technology equivalency matrix analysis
Alternative Fugitive Emissions Methane Detection technology evaluation matrix report. A report prepared by Highwood Emissions Management for the Alberta Energy Regulator outlines alternative LDAR programs that are “equivalent” from a performance perspective to the regulatory OGI LDAR. It is useful for professionals looking to understand the trade-off between different technology classes.
Optical gas imaging stakeholder workshop
The EPA’s webpage provides resources from the OGI Stakeholder Workshop, including presentations on OGI technology, its applications, regulatory considerations, and performance evaluation. Examples of resources include case studies, guidance on best practices, and discussions on integrating OGI into emissions monitoring programs. Useful for professionals working directly with methane detection and quantification programs.
Methane emissions technology evaluation center
Methane Emissions Technology Evaluation Center(METEC). METEC is a cutting-edge controlled-release testing facility designed to evaluate methane detection and measurement systems under realistic field conditions. METEC supports innovation by simulating diverse leak scenarios found in oil and gas operations, enabling developers to validate and refine their technologies. The facility collaborates with industry, academia, and regulators to […]
Where the methane is – insights from novel airborne LiDAR measurements combined with ground survey data
This study combines airborne LiDAR measurements, parallel controlled releases, and on-site optical gas imaging (OGI) survey and pneumatic device count data to derive a new measurement-based methane inventory for oil and gas facilities in British Columbia, Canada. Results reveal a surprising distinction between the higher magnitudes, different types, and smaller number of sources seen by […]
MiQ compatibility assessment
The MiQ Foundation, as the Standard holder, has developed this monitoring technology compatibility assessment to streamline market research conducted by Operators and other stakeholders to assess the compatibility of methane monitoring technologies against the requirements in the Monitoring Technology Deployment pillar of the MiQ Standard. This resource is particularly useful for companies selecting technologies to […]
Advanced methane technology alternative test method portal
EPA portal to submit requests for alternative test methods (ATM). ATM request has three primary pieces: 1) a document describing how your technology works, from first principles through the solution; 2) supporting documents demonstrating the technology works as stated and showing applicability; 3) the formal ATM. All those documents are available in the portal for all […]
