DICKINSON, N.D. (AP) -- A Dickinson man has died in an incident in the western North Dakota oil patch.
The Dunn County Sheriff's Office says 25-year-old Ryan Provancher was working on pipes at an oil pumping site northwest of Killdeer on Oct. 9 when he was exposed to hydrogen sulfide gas.
A man working with Provancher was able to escape the gas unharmed.
The co-worker and emergency officials unsuccessfully tried to revive Provancher at the scene. He died at a Dickinson hospital two days later.
