Energy sector's methane leaks rise despite green plans
Satellite images show the number of large methane leaks from the oil and gas industry rose by nearly a third in the first eight months of this year to over 5,000, despite the sector's pledges to reduce greenhouse emissions, data firm Kayrros said.
Methane is almost 90 times more potent a greenhouse gas than carbon dioxide in its first 20 years in the atmosphere.
Kayrros, which counts leaks above 5 tons an hour as hotspots, said leaks in the year to end August in Algeria, Russia and Turkmenistan rose by more than 40%, above the overall global increase of 32%.
Retrofitting and regular maintenance at oil and gas infrastructure to prevent leaks, venting and flaring of methane is costly, and the sector is currently facing a coronavirus-linked oil price slump and a market glut.
"It's a pure consequence of cost cutting," Kayrros president Antoine Rostand said. "Such increases in methane emissions are concerning and in stark contradiction to the direction set in the Paris Agreement of 2015 (to keep global warming below 1.5 degree Celsius)."
"In 2019 alone, our technology tracked a combined volume of visible large methane leaks of 10 million tons, equivalent to over 800 million tons of CO2 over a 20-year period."
In 2019, the largest emitters were the United States, Russia, Algeria, Turkmenistan, Iran and Iraq, Rostand said.
Pledges to reduce methane leaks are more prevalent among listed producers such as BP and Exxon than at national oil companies.
Kayrros' research is part of a growing effort in recent months by data companies, academics and some energy producers to use technology to find the biggest methane leaks.
The European Union, the world's biggest gas importer, is considering binding methane emissions standards for the natural gas it buys, it said.

Regional Focus: The role of small-scale LNG in Russia’s energy agenda
-Lorenzo Micucci, John Motta
A number of factors are challenging Russia’s position in the energy markets: the change in the global natural gas landscape, the abundance of gas, expanding LNG trade, and the increased interconnectivity among pipeline systems that makes possible reverse flows.
GasPro 2.0: A Webcast Symposium
Following the successful GasPro Webcast Symposium in October 2019, the third GasPro Webcast Symposium will take place on October 21, 2020.
The 2019 webcast drew attendees from around the world, with more than 80% of the audience working in company management or engineering divisions.
The 2020 web event will gather experts in the fields of LNG, gas processing and process safety to share market, operations and engineering technology and trends with our audience.
Attendees of the 2020 webcast will learn about market solutions and technology deployments in a number of areas: LNG delivery infrastructure, small-scale desulfurization for NGL, H2S removal for gas treating, process safety for safety instrumented systems, small-scale LNG project design, and advances in freeze component removal for LNG.
