BISMARCK, N.D. (AP) -- Iraqi and U.S. Energy Department officials toured western North Dakota this week to look at technologies the state is using to curb the wasteful burning of natural gas that's a byproduct of oil production.
The Energy Department's Julio Friedmann says Iraq and North Dakota have had the same problem dealing with excess natural gas with the rapid development of oil. But he says the North Dakota has made big strides to cut down on flaring.
North Dakota officials say the industry has invested more than $11 billion in infrastructure to capture and process natural gas in the past eight years.
Friedmann says Iraqis were impressed by North Dakota's gas-capturing efforts and hope to use them in that country.
