Project Canary's Findings Reveal Short-Lived Methane Events Majorly Impact Total Emissions
In a groundbreaking analysis, Project Canary, a frontrunner in emissions management, has revealed critical insights regarding methane emissions gathered from one of the most extensive continuous monitoring datasets in the field. The dataset incorporates 24.7 million 15-minute measurements from 940 upstream production facilities across seven major U.S. basins. This extensive data allowed researchers to identify the nuances of how emissions occur during short-lived events, ultimately reshaping the understanding of emission profiles within the energy sector.
Key Findings of the Study
1. Redefining Super Emitters: Traditionally, super emitters—facilities emitting over 100 kilograms of methane per hour—have been viewed as the leading culprits of drastic emissions. However, the findings indicate that these emitters are responsible for only 10% to 20% of overall emissions, while facilities emitting below 100 kilograms per hour contribute a staggering 80% to 90%.
2. Impact of Short Events: An astonishing 75% of emissions associated with events last for three days or less. This revelation puts into perspective the importance of rapid response and monitoring features that can identify these brief but impactful emissions.
3. Concentration of Emissions: The analysis illustrated that just 11% of the monitored facilities are responsible for half of the total estimated methane emissions, highlighting the concentrated nature of emissions across select sites.
4. Intermittent Emission Patterns: Approximately 4% of the monitoring intervals experienced emissions events, yet those periods accounted for roughly 41% of the total estimated emissions. This disparity suggests that conventional monitoring methods may overlook significant emissions periods.
5. Event Duration Matters: Many emission events occur over hours or days, not the months often assumed. Programs that base their interventions on the notion that emissions are continuous without further verification may misallocate resources and misrepresent impacts.
Implications for Leak Detection and Repair Programs
The insights drawn from this analysis greatly affect Leak Detection and Repair (LDAR) programs that often rely on singular snapshot measurements to assess methane emissions. With emissions starting and halting rapidly, a flyover or brief measurement could miss major events altogether or misdetect them after they have ceased, resulting in unreliable fieldwork opportunities and misaligned operational responses.
Will Foiles, CEO of Project Canary, emphasizes the importance of real-time methane data reflecting emissions' specific behaviors. "This analysis indicates that intermittent emissions are a consistent characteristic of many locations. When assumptions are made about emissions persistence until the next review, it can inflate monetary savings and misdirect field efforts. Integrating various data forms—including operational SCADA data—is crucial for obtaining contextual awareness to swiftly respond to ongoing issues while eliminating unnecessary deployments."
Project Canary intends to further disseminate technical aspects of this study through a peer-reviewed journal, providing deeper insights into methods, definitions, and limitations. All data put forth will be anonymized and aggregated, ensuring that individual operators or facilities remain unidentifiable to maintain confidentiality.
Operators keen on leveraging these findings for their LDAR strategies are encouraged to engage with Project Canary to explore the operational implications more thoroughly. About Project Canary
