Addressing methane leaks effectively: Strategies for mitigation. Discover advanced technologies and solutions offered by Atmeco Integrity Services.
The underestimated impact of methane, an often-overlooked greenhouse gas, has far-reaching consequences for climate change. Delve into the importance of methane reduction and a possible solution.
While carbon dioxide is widely recognized as a major contributor to global warming, methane emissions are also a crucial concern. According to the International Energy Agency (IEA), methane emissions account for nearly 16% of global greenhouse gas emissions. The energy, agriculture, and waste management sectors are substantial contributors to global methane emissions, with the energy sector alone accountable for 35% of emissions.

As a potent greenhouse gas (GHG), Methane poses a significant, yet invisible threat to our environment. This odorless, colorless gas, chemically denoted as CH4, is the primary component of natural gas and is more efficient at trapping heat than carbon dioxide. Its warming potential is approximately 25 times greater than that of carbon dioxide over a 100-year period. Methane emissions are crucial for achieving the 2050 climate objectives and also contribute to local air pollution, ozone formation, and associated health issues.
Methane can leak across the gas production and supply chain.
Methane leakage in the Oil & Gas industry
According to the International Energy Agency's Methane Tracker 2020 report, the oil and gas sector is a significant source of methane emissions. Methane leakage during the extraction, production, and distribution of oil and gas contributes substantially to overall global emissions. It is estimated that the global oil and gas industry can achieve a remarkable 75% reduction in methane emissions using currently available technologies, with two-thirds of this reduction achievable at no net cost.
The cost of leakage
Beyond environmental concerns, methane leaks have substantial economic consequences. The value of lost methane, often referred to as "fugitive emissions," escaping from global supply chains amounts to billions of dollars each year. These losses not only impact companies' bottom lines but also represent a wasted energy resource.
The Environmental Defense Fund's groundbreaking five-year research series in the U.S. revealed that at least 13 million metric tons of methane - a figure 60% higher than estimates by the Environmental Protection Agency (EPA) - are lost to leaks each year. The magnitude of this leakage is staggering, equating to enough gas to power 10 million homes for a year. Financially, this represents an estimated $2 billion worth of natural gas wasted annually.
Addressing methane leaks promptly
Implementing effective methane abatement measures is crucial for mitigating emissions across different sectors. Strategies highlighted by the International Energy Agency include advancements in methane detection and measurement technologies, improved maintenance and repair practices, and the utilization of advanced leak detection and repair programs. Furthermore, reducing methane emissions from coal mining, minimizing methane venting and flaring in oil production, and adopting sustainable agricultural practices are emphasized as key areas for action.

Identifying methane leak points
Unintentional leaks of natural gas can occur in various components of equipment used in oil and gas operations. These leaks are often caused by mechanical and thermal stresses, as well as wear and loss of tightness in joints, seals, and rotating surfaces over time. Understanding the potential leak points is crucial for effective detection and mitigation. Here are examples – provided by the Oil & Gas Methane Partnership 2.0 (OGMP 2.0) – of components and associated leak points in equipment:
Connections: Flanges, threaded connections, tube fittings, and other types of joints/seals
Open ended lines: Closed valve leaks directly to the atmosphere or through an open vent pipe
Blow-down open-ended line: Leaks through blow-down valves
Valves and control valves: Leaks in stem, gland, bonnet, and other sealing components related to valve shafts
LNG pumps, rotary compressors, and agitators: Leaks in shaft seals such as rotary screw, rotary vane, and scroll compressors, excluding design emissions
Covers: Leaks in manways, boilermakers, blind flanges, access hatches, and other components
Others: Leaks in grease nipples and additional components
