North Dakota's oil production hit a five-month high and climbed back over 1 million barrels per day in October, after falling below that yardstick for two consecutive months.
The state pumped out 1.043 million barrels per day in October — up 7 percent over September — as oil prices rose, according to data released Tuesday by the North Dakota Department of Mineral Resources. The state hit its all-time high production mark of 1.23 million barrels per day in December 2014.
Lynn Helms, director of the mineral resources department, called October's production increase a "surprise."
In August, North Dakota's oil output dipped below 1 million barrels per day for the first time since March 2014, and repeated that performance in September. It was a trend expected to continue.
Still, Helms said in a web conference with reporters Tuesday that he "wouldn't expect a repeat of October in these winter weather months." With the cold descending on North Dakota, fracking for oil becomes more expensive and more complicated.
North Dakota, the nation's second largest oil producing state, has been hammered by falling prices over the past two years — along with the entire U.S. petroleum industry. There are some signs for optimism, though.
"Oil prices are up, activity is up, production is up," Helms said.
Oil prices Monday hit a one-year high. West Texas Intermediate (WTI) — a benchmark crude — traded down a bit Tuesday, but still closed at nearly $53 a barrel. For much of last winter, WTI traded below $35 a barrel.
