BISMARCK, N.D. (AP) -- A University of North Dakota researcher says that about 270 oil wells are responsible for 60 percent of all the natural gas flaring in the state. Chad Wocken is a senior research manager at UND's Energy and Environmental Research Center. Wocken says there is no ``silver bullet'' to cut the amount of natural gas that oil drilling companies are burning and wasting instead of capturing.
He says the center is exploring the efficiency of different methods to capture gas in remote sites. North Dakota wells currently flare more than 30 percent of the gas because development of pipelines and processing facilities to capture it hasn't kept pace with oil development.
Around 1 percent of natural gas is flared from oil fields nationwide.
Wocken on Tuesday spoke at the Williston Basin Petroleum Conference and Expo.
