The Williston Basin is known for its oil and gas reserves.
"We know that there's helium there in the Basin," said state geologist Ed Murphy. "That's from what little records we have on that."
Murphy said the Canadians have much more information on this.
"They've got economic quantities of helium, produced in the 1960s and 1970s," Murphy said. "They're back in now with a big drilling program."
Murphy said that program is centered on southern Saskatchewan.
"And we're saying, 'Let's take a look at North Dakota,'" Murphy said.
