BISMARCK, N.D. (AP) - Authorities say a man died and three others were injured in an oil well explosion in western North Dakota.

The McKenzie County Sheriff's Department says 52-year-old Johnny Stassinos of Rock Springs, Wyoming, died Saturday afternoon from injuries suffered that morning at a well site operated by XTO Energy Inc. near Watford City.

Officials say 28-year-old Daniel Montes of Fruita, Colorado, and 27-year-old Richard Maheu of Rock Springs, Wyoming, were airlifted to the Regions Burn Center in St. Paul, Minnesota, where they were listed in critical condition. Authorities say 40-year-old Justin Pyle of Grand Junction, Colorado, was treated for minor injuries at a Watford City hospital and later released.

XTO Energy is a subsidiary of ExxonMobil. A spokeswoman says the men were contractors working for companies that do maintenance on oil wells.
