Argonne analysis shows greenhouse gas emissions similar for shale, conventional oil

Green Car Congress

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. For the Bakken, GREET-derived WTR (well-to-refinery gate) GHG intensities range from 4.3 for diesel, and 5.1
