Identification and monitoring of Oil & Gas methane emissions

Conducting regular leak survey, pinpointing and repairs on natural gas distribution grids have been used for decades to assure utilities remain safe and efficient. Recently, the significance of this routine work has grown as a method of reducing the effects of greenhouse gas emissions fast and effectively.

New data show U.S. Oil & Gas methane emissions are over four times higher than EPA estimates, eight times greater than industry target. That’s enough wasted gas to meet the annual energy needs of over half of U.S. homes. These alarming numbers highlight the urgent need for effective measures to detect and repair methane leaks in the U.S. 

Methane is a very potent greenhouse gas with 84 times the global warming potential of CO₂ over a period of 20 years. The difference is that methane decomposes significantly faster, which means that reduced methane emissions can have a faster positive effect on global warming. Reducing methane emissions can be challenging when old methods and outdated instruments are used. The main challenges are:

• Sensitivity: Older instruments may lack the sensitivity needed to detect low levels of methane emissions accurately. This can result in underreporting or even completely missing potentially harmful leaks.
• Precision: Outdated instruments may have lower precision, making it difficult to pinpoint the exact source of methane emissions. This can hinder timely and targeted repairs.
• Response Time: Older devices might have slower response times, leading to delays in identifying and addressing methane leaks promptly. Swift detection is crucial for minimizing environmental impact and ensuring public safety.
•  Technological Limitations: Old instruments may not leverage the latest technological advancements, such as advanced sensors and data integration capabilities, limiting their overall effectiveness in detecting and monitoring methane emissions.
•  Maintenance Challenges: Aging instruments may be more prone to malfunctions and require frequent maintenance. This can result in downtime, increased costs, and decreased overall reliability.
•  Compliance Issues: Meeting regulatory requirements becomes more challenging with outdated instruments, potentially leading to non-compliance issues and legal consequences.
•  Data Integration: Older instruments may lack compatibility with modern data integration systems, hindering the seamless collection, analysis, and reporting of methane emission data.
• Cost Inefficiency: While it may seem cost-effective to continue using old instruments, the long-term costs associated with inefficiency, frequent maintenance, and potential environmental consequences can outweigh the initial savings.
