Mr. Hamm and his company have pioneered the development of America's premier oil play—the Bakken Play of North Dakota and Montana. With an estimated 24 billion barrels of oil, the Bakken is the nation's largest oil discovery in more than 40 years.

Note the estimated reserves: 24 billion barrels. No source provided for that estimate, but I believe that it Harold Hamm's assessment. The USGS assessment is significantly lower.
