"Satellites and aircraft will help oil-and-gas watchdogs find and report large leaks."
"Scientists with NASA’s Jet Propulsion Laboratory were flying a plane equipped with a visible-infrared imaging spectrometer over an oil field in California’s San Joaquin Valley when they made a worrisome discovery. Images produced by the device revealed a large plume of methane lingering in the air.
The plane made flights over the field for several more weeks, and while the plume shifted and changed shape with the blowing wind, its presence persisted. Believing the source could be a leak at the oil well, the scientists notified the operator. Soon, the plume disappeared. The leak, coming from a small fuel line, had been repaired.
“This is the essence of proactive measurement,” Riley Duren, one of the scientists involved in the flights and now CEO of Carbon Mapper, told Grist. “It’s a good example of how you would want it to work.”"
