The flow of crude oil from North Dakota's fields is backing up at a terminal in Clearbrook, Minnesota. The Canadian company that owns the terminal says the outgoing pipeline is operating at capacity and needs an upgrade. But a North Dakota competitor suspects the company is favoring tar sands oil from north of the border.

Wisconsin Public Radio reports a vehicle crash in Illinois has disrupted pipelines that carry crude oil from the Alberta tar sands to refineries in the Midwest. The Enbridge pipeline moves 318,000 barrels of oil a day. A spokeswoman could not say how the disruption might affect refineries in the region.

The new study by Bentek Energy LLC of Colorado shows North Dakota's oil production could jump to more than two million barrels a day by 2025, the Associated Press reports. Natural gas production could also more than quintuple. Unfortunately, about a third of the natural gas produced in North Dakota is wasted because there's a lack of pipelines.

The number of oil drilling rigs at work in North Dakota is leveling off, and a state regulator says that's a good thing because the pause "will allow infrastructure and various other things to catch up."

North Dakota's oil boom is fueling demand for more air travel. Delta Air Lines is adding two nonstop daily flights between the Minneapolis-St. Paul International Airport and Williston, N.D., starting in November, the Fargo Forum reports.

An oil boom has brought great prosperity – but also great amounts of waste – to North Dakota, investigative reporting by ProPublica reveals. Data obtained by ProPublica show oil companies are spilling and dumping drilling waste onto North Dakota's land and into its waterways with increasing regularity. Many dumpings along roads and in pits go unreported, state regulators acknowledge.
