Research Suggests Offshore Oil’s Methane Pollution Is Underestimated
Flying 10,000 feet above the Gulf of Mexico, in a plane outfitted with infrared imaging equipment, researchers could see methane gas bubbling under water, likely from an undetected pipeline leak.
Over the course of several flights in 2021, they spotted frequent gas plumes from platforms, storage tanks, and pipelines offshore, leading the team to believe that the 151 platforms near the Louisiana coast had a much higher methane leak rate than what’s been measured for onshore oil and gas production.
“I think the bottom line message in this study is there’s a lot of emissions in the shallow waters that are currently unmeasured,” said Riley Duren, the CEO of Carbon Mapper and coauthor of the nonprofit’s 2022 study of offshore methane emissions.
New technologies are allowing for actual measurements of oil and gas methane emissions like never before, whether from leaks or intentional flaring and venting.
