The Parshall Oil Field is an oil field producing from the Bakken Formation and Three Forks Formation near the town of Parshall, in Mountrail County, North Dakota. The field is in the Williston Basin. The field was discovered in 2006 by Michael Johnson and sold the play to EOG Resources, which drilled, and now operates, most of the wells. It was the discovery of the Parshall Field that was largely responsible for the North Dakota oil boom. Parshall's break-even price is at US$38/barrel, which is the lowest on the Bakken Formation; overall, Bakken's break-even point is of US$62/barrel.
