Shale oil production generates greenhouse gas emissions at levels similar to conventional crude oil production, according to a pair of new studies released by the US Department of Energy’s Argonne National Laboratory.
The research, conducted by Argonne researchers in collaboration with Stanford University and the University of California, Davis, analyzed the Eagle Ford shale formation in Texas and the Bakken play mainly in North Dakota. Eagle Ford and Bakken are the second and third largest oil-producing shale formation regions in the United States, during the last three years. In 2014, Bakken and Eagle Ford together accounted for 54% of oil production and 19% of gas production among the top seven production regions. . . .
Both Argonne studies showed that, after taking into consideration flaring and venting of natural gas, the greenhouse gas emissions associated with shale/tight oil production are similar to those generated at conventional crude oil reserves. This emission intensity stays consistent during the lifespan of extraction at the oil play. This contradicts an earlier estimate that the Bakken play might produce greenhouse gas emissions 20% higher more than for crude oil production. . . .
