KEENE, N.D. (AP) — North Dakota officials say more than 10,000 gallons of a mixture of oil and produced water have spilled at a well site in McKenzie County.
The state’s Oil and Gas Division says the incident happened Tuesday at a site about 10 miles southeast of Keene. Officials say the incident was caused by a “piping connection leak.”
The division says more than 9,500 gallons of the mixture have been recovered. Clean-up efforts are ongoing. A state inspector visited the site Wednesday.
Produced water is a mixture of saltwater and oil and can contain drilling chemicals.
Hess Bakken Investments II operates the site. A company spokeswoman did not immediately return a call seeking comment Wednesday.
