Texas continues to be the top oil producing state in the US.
But now, there’s a race for second place.
North Dakota has been second – but New Mexico is giving the state a run for its money.
"More than likely, it's a toss-up," said North Dakota Mineral Resources Director Lynn Helms, in his monthly "Director's Cut" report. The report reflects April production numbers.
North Dakota’s April oil production was just over 1.2 million barrels a day – an increase of 1.1 percent over March.
"It's a horse race right now," Helms said.
