I keep waiting for news that the Chinese state oil company, CNOOC, has come to the Bakken. But it looks like another Asian company may have gotten here first (yes, I know Chinese ceramics are all over the Bakken, but I am not aware of a Chinese company actually operating in the Bakken, but I could be wrong). But I digress.
Matheson Tri-Gas is in the process of establishing a facility just outside Dickinson's city limits to provide pure nitrogen for use during the casing aspect of the hydraulic fracturing process.
MTG is headquartered in New Jersey. It is a subsidiary of Taiyo Nippon Sanso, a large Japanese corporation.
See link at the Dickinson Press/InsideClimate News.
Matheson Tri-Gas has quite a history; very interesting; as is its parent company.
