Daily oil production in North Dakota dropped slightly in December, compared with November.
"We saw a 1.4 percent drop," said state Mineral Resources director Lynn Helms at his monthly "Director's Cut" briefing. "We lost about 16,000 barrels a day statewide."
The numbers: December production was 1,181,319 barrels a day. In November, the number was 1,196,976.
Helms said the weather had a lot to do with the drop.
