An oil spill that occurred Friday at an Enerplus-operated wellsite in North Dakota has been contained and recovered.
The 250-barrel release happened at the Bait wellsite about seven miles southwest of Mandaree, which lies within the Fort Berthold Indian Reservation.
The spill occurred when a valve failed and a caused a tank to overflow, said officials at Enerplus.
A state inspector has been to the site, said officials at the state’s Oil and Gas Conservation Division.
While North Dakota is a leader in terms of fracking and producing oil and gas, in the year ending on May 1, the state’s oil and gas industry reported 745 involved oil spills — on average, a spill every 11 hours and 45 minutes, according to the state’s Department of Health.
