North Dakota's daily oil production fell 2 percent in September as slipping crude prices again weighed on the state's energy industry and forced cuts in the use of drilling rigs and fracking crews.

The state produced 1,162,253 barrels of oil per day (bpd) in September, compared with 1,187,631 bpd in August, according to the Department of Mineral Resources, which reports on a two-month lag.

Natural gas output fell 3 percent to 1,603,785 million cubic feet per day.

The number of producing wells fell by six to 13,025, though state officials permitted one more well in September than in August.

The count of drilled-but-uncompleted wells jumped by 95 to 1,091, eclipsing 1,000, which had been seen as an inevitable milestone across the state's oil patch as oil producers delay fracking new wells in hopes that oil prices will rise.
