The release started at approximately 10:15 p.m. on August 14, 2012. The oil shot over 9.1 meters (fifty feet) into the air. The uncontrolled release continued until it was contained by Boots and Coots well control nine hours later. The employee was directing activities to control the release. He was 0.8 kilometers (0.5 miles) west of the intersection of 125th Street and 48th Street NW in Williston ND. He was struck by a pickup truck that was being moved.
