Williston, N.D. (AP) Authorities say workers are attempting to contain an out-of-control oil well in North Dakota.
North Dakota regulators announced Friday that a well near Watford City in the western part of the state has been leaking oil, gas and water since Thursday. But they say there's no immediate health risk.
The well is owned by XTO Energy Incorporated. Regulators say a mechanical problem at the wellhead is being blamed for the problem.
Officials say inspectors were at the site Friday. They were working with the company to control the leak.
Authorities say about 300 barrels of oil and water have been contained and recovered at the well location.
Regulators say an undetermined amount of mist left the well location. Inspectors are working to determine where it went.
