DENVER – Towering flames atop oil wells break the inky darkness in the badlands on North Dakota's Fort Berthold Indian Reservation. The flares of natural gas set grass fires on the prairie where Theodora Bird Bear's ancestors hunted buffalo and create a driving hazard on rural roads.
"At nighttime, clouds of gravel dust from semis are lit up with flaring lights," said Bird Bear, 62, who can see flames shooting from a well behind land where she grows red beans, corn and squash. "It's a hellish scene."
Twice as much natural gas is wasted through flaring than in 2012 amid an energy boom that's propelled North Dakota's torrid economic growth. The state's employment expansion has been the fastest in the U.S. for four years. In the rush to exploit the Bakken shale formation, which holds the nation's second-largest oil supply, companies from Statoil ASA to Whiting Petroleum are stepping in to try to capture more of what's being lost.
Natural gas that's burned in flaring is a byproduct of crude oil. Without enough pipelines to transport the gas, or the refinery capacity to process it, about a third of what's released each day, worth $1.4 million, goes up in smoke. Tribal members say as much as 70 percent of gas from wells on the reservation is flared.
"We're confessing that we are flaring a tremendous amount of gas right now," Gov. Jack Dalrymple said at a February conference in Washington. "Everybody feels it's a huge waste, to say nothing of the environmental impact."
The energy business has been fueling an economic bonanza in North Dakota, with jobs growth of 3.7 percent last year.
As a polar vortex weather pattern caused a nationwide propane shortage this winter, energy companies in the Bakken flared gas rich in propane. More gas is flared in the state than in any other domestic oil field and at a level equal to Russia and twice that in Nigeria.
Black carbon emitted by flares and trucks affects health and contributes to climate change, according to a study by Colorado State University and the National Park Service.
