Deborah Sontag and Robert Gebeloff, The Downside of the Boom. The New York Times, Part 1 of a 3-Part Series, 22 November 2014. “Since 2006, when advances in hydraulic fracturing — fracking — and horizontal drilling began unlocking a trove of sweet crude oil in the Bakken shale formation, North Dakota has shed its identity as an agricultural state in decline to become an oil powerhouse second only to Texas. A small state that believes in small government, it took on the oversight of a multibillion-dollar industry with a slender regulatory system built on neighborly trust, verbal warnings and second chances.” Part 2, Deborah Sontag, Where Oil and Politics Mix. 23 November 2014. Part 3, Deborah Sontag and Brent McDonald, In North Dakota, a Tale of Oil, Corruption and Death. 28 December 2014.
