Enhanced oil recovery being studied

The Energy & Environmental Research Center (EERC) at the University of North Dakota is studying if enhanced oil recovery would be economically viable in the Bakken Formation of the Williston Basin, a method that includes injecting carbon dioxide underground to increase oil production in the formation. John Harju, associate director of research at EERC, said that even if an additional 1 percent of oil is recoverable, that could translate into $150 billion. Researchers hope to field test within two years, as time is short. Carbon injection needs higher pressure in the formation to work well, which can be a challenge as oil reserves are depleted.
