Post Carbon Fellow David Hughes was quoted in this article on the downturn in shale oil production in North Dakota.

From the article:

Although some shale oil analysts see production ramping up once oil prices begin rising again, David Hughes, a fellow at the California-based Post Carbon Institute, takes a more cautious view.

“When prices go up, a lot of the best locations have already been drilled off,” Hughes told AMI Newswire.

About one-third of the oil in North Dakota’s Bakken Formation has already been removed, he said, and even though the fields will continue to produce oil for a couple more decades, well productivity will inevitably drop.
