Accounting for Denver’s Ozone

First study to quantify effect of oil and gas emissions on ozone problem

The first peer-reviewed study to quantify oil and gas emissions on Colorado's northern Front Range confirms that energy development is an important contributor to the region’s chronic ozone problem. The NOAA-CIRES research was published August 8 in the Journal of Geophysical Research: Atmospheres

The Bakken oil and gas field is leaking a lot of methane, but less than some satellites report, and less than the latest Environmental Protection Agency inventory for petroleum systems, according to the researchers’ calculations. That's the finding of the first field study measuring emissions of this potent greenhouse gas from the Bakken, which spans parts of North Dakota and Montana. The work was published today in the Journal of Geophysical Research: Atmospheres

New NOAA-led study measures soot from North Dakota flaring in oil and...

Flaring produces an estimated 4 tons of black carbon per day, not considered significant for climate

In the lonely reaches of northwestern North Dakota and across the border into Saskatchewan, the vast Bakken oil field hosts extensive activities to extract both crude oil and natural gas. Business is booming—production increased by 30 percent between May 2013 and May 2014. More than a quarter of the total gas produced from the Bakken operations can’t be processed fast enough, though, and the common industry practice is to flare it—burn it off as it is vented to the atmosphere. Jutting 30 feet upward like enormous lit matchsticks, the flares pose a new question for atmospheric scientists: What do the flares put into the air? A new NOAA-led study has produced the first direct measurements of how much black carbon—a major component of airborne particles that are commonly referred to as soot —is emitted by the Bakken flaring operations.

Scientists probe methane mystery in Four Corners

Satellite pinpointed methane emission hotspot in remote region

A team of scientific investigators is now in the Four Corners region of the U.S. Southwest, aiming to uncover reasons for a mysterious methane hotspot detected from space by a European satellite. The joint project is working to solve the mystery from the air, on the ground, and with mobile laboratories.
