Until a few years ago it was unprofitable to produce oil from shale in the United States. The steep slide in costs could encourage more U.S. shale output if OPEC members cut supplies, undermining the producer group's ability to boost prices. OPEC ministers meet Wednesday to weigh output cuts to end a two-year glut that has pressured global oil prices.
In shale fields from Texas to North Dakota, production costs have roughly halved since 2014, when Saudi Arabia signaled an output free-for-all in an attempt to drive higher-cost shale producers out of the market.
In Dunn County, North Dakota, there are around 2,000 square miles where the cost to produce Bakken shale is $15 a barrel and falling, according to Lynn Helms, head of the state's Department of Mineral Resources.
"The success in Dunn County has been fantastic," said Ron Ness, president of the North Dakota Petroleum Council.
Dunn County's cost is about the same as Iran's, and a little higher than Iraq's. Dunn County produces about 200,000 barrels of oil a day, about a fifth of daily production in the state.
It is North Dakota's sweet spot because it boasts the lowest costs in the state, yet improved technology and drilling techniques have boosted efficiency for the whole state and the entire U.S. oil industry.
The breakeven cost per barrel, on average, to produce Bakken shale at the wellhead has fallen to $29.44 in 2016 from $59.03 in 2014, according to consultancy Rystad Energy. It added that in terms of wellhead prices, Bakken is the most competitive of major U.S. shale plays.
Wood Mackenzie said technology advances should further reduce breakeven points.
Landlocked Bakken producers still need a substantially higher international price than their breakeven cost to make a profit, since they pay more to transport crude to market than producers in most other U.S. regions.
International oil prices of $45 a barrel are enough for some Bakken producers to profit, Ness said, and $55 would encourage production growth.
For OPEC ministers meeting in Vienna on Wednesday, a major concern is that an output cut would encourage a quick response from U.S. shale producers, who have slashed costs and have been steadily adding drilling rigs.
"Right now, OPEC understands we're in a push-and-pull experiment with the United States," said Michael Tran, director of energy strategy at RBC Capital Markets in New York.
"Two years ago, we thought prices hovering around $50 to $60 meant that non-OPEC production growth would end. But U.S. production came back stronger."

"Everybody is drilling wells faster and completing them better," said Mike Breard, an energy stock analyst at Hodges Capital Management in Dallas. "It's not just a Bakken phenomenon."
Breard said he prefers shale stocks in the Permian basin in Texas, where he is expecting more big gains in production next year. He is eyeing firms such as Parsley Energy Inc

"Simply put, we can deliver more production with fewer wells," Vicki Hollub, the company's president and chief executive, told analysts on a recent call.
