An equipment failure caused about 163 barrels, or 6,846 gallons, of crude oil to spill Saturday at a well pad in Dunn County, according to a report released by the North Dakota Department of Health on Tuesday, Dec. 11.
The spill occurred about 11 miles north of Killdeer at a site owned by Burlington Resources Oil & Gas Co. About 150 barrels, or 6,300 gallons, were recovered, but the rest of the oil migrated through a stormwater gate in the berm and contaminated rangeland, the department said.
The spill was caused by a failed wellhead valve.
Health department staff are inspecting the site and will monitor the investigation.
