Bakken (Montana and North Dakota)

The Bakken play is smaller than the Eagle Ford play. It produces about 1 million barrels of oil per day. The gas production is significantly less than most of the others, only getting about 1 billion cubic feet of natural gas per day. This has long been known as a great shale play, but until recently the technology was not available to properly drill here. It has been considered one of the best and biggest oil discoveries in recent history.
