For those too young to remember, the Bakken Shale was once an up-and-coming oil and gas behemoth, the darling of the North, a key component of U.S. energy security.

That was prior to the downcycle, prior to the mandate that all energy-related articles make reverent mention of the Permian Basin. But now the Bakken, the second-largest unconventional play in the U.S., is growing again, propped up by oil prices that are comfortably above $60 per barrel (bbl).
