Hidden Menace: Massive methane leaks speed up climate change
To the naked eye, the Mako Compressor Station outside the dusty West Texas crossroads of Lenorah appears unremarkable, similar to tens of thousands of oil and gas operations scattered throughout the oil-rich Permian Basin.
What's not visible through the chain-link fence is the plume of invisible gas, primarily methane, billowing from the gleaming white storage tanks up into the cloudless blue sky.
The Mako station, owned by a subsidiary of West Texas Gas Inc., was observed releasing an estimated 870 kilograms of methane – an extraordinarily potent greenhouse gas — into the atmosphere each hour. That's the equivalent impact on the climate of burning seven tanker trucks full of gasoline every day.
But Mako's outsized emissions aren't illegal, or even regulated. And it was only one of 533 methane “super emitters” detected during a 2021 aerial survey of the Permian conducted by Carbon Mapper, a partnership of university researchers and NASA's Jet Propulsion Laboratory.
The group documented massive amounts of methane venting into the atmosphere from oil and gas operations across the Permian, a 250-mile-wide bone-dry expanse along the Texas-New Mexico border that a billion years ago was the bottom of a shallow sea. Hundreds of those sites were seen spewing the gas over and over again. Ongoing leaks, gushers, going unfixed.
“We see the same sites active from year to year. It's not just month to month or season to season,” said Riley Duren, a research scientist at the University of Arizona who leads Carbon Mapper.
Carbon Mapper identified the spewing sites only by their GPS coordinates. The Associated Press took the coordinates of the 533 “super-emitting” sites and cross-referenced them with state drilling permits, air quality
