One oil field (the Bakken Formation) a key culprit in global ethane gas increase

[font size=3]ANN ARBOR—A single U.S. shale oil field is responsible for much of the past decade's increase in global atmospheric levels of ethane, a gas that can damage air quality and impact climate, according to new study led by the University of Michigan.
The researchers found that the Bakken Formation, an oil and gas field in North Dakota and Montana, is emitting roughly 2 percent of the globe's ethane. That's about 250,000 tons per year.
"Two percent might not sound like a lot, but the emissions we observed in this single region are 10 to 100 times larger than reported in inventories. They directly impact air quality across North America. And they're sufficient to explain much of the global shift in ethane concentrations," said Eric Kort, U-M assistant professor of climate and space sciences and engineering, and first author of the study published in Geophysical Research Letters.
The Bakken is part of a 200,000-square-mile basin that underlies parts of Saskatchewan and Manitoba in addition to the two U.S. states. It saw a steep increase in oil and gas activity over the past decade, powered by advances in hydraulic fracturing, or fracking, and horizontal drilling.
