There is a lot of oil coming out of the Bakken shale in North Dakota, the federal government reports today.
According to the U.S. Energy Information Administration:
"North Dakota's oil production averaged 660 thousand barrels per day (bbl/d) in June 2012, up 3% from the previous month and 71% over June 2011 volumes. Driving production gains is output from the Bakken formation in the Williston Basin, which averaged 594 thousand bbl/d in June 2012, an increase of 85% over the June 2011 average. The Bakken now accounts for 90% of North Dakota's total oil productio."
"Production gains in the Bakken formation are the result of accelerated development activity, primarily horizontal drilling combined with hydraulic fracturing. According to the North Dakota Department of Mineral Resources, there were a total of 4,141 producing wells in the North Dakota Bakken in June 2012, up 4% from May 2012 and up 68% from the number of producing wells in June 2011"
Plus: "The transportation system—oil pipelines, truck deliveries, and rail—to move crude oil out of the area is being affected by constraints due to growth in crude oil production from the Bakken formation"
