The growing eruptions at Mount Redoubt in Alaska have forced energy company Chevron to suspend production from its Cook Inlet oil operations and indefinitely shutdown a tank farm it uses for storage.
The companys normal production was around 7,500 barrels a day from the 10 offshore platforms it operates in Cook Inlet. Redoubts nineteenth explosion finally led the company to suspend operations on 5 April.
The most recent explosion interrupted a tanker-loading operation at the Drift River Oil Terminal that had been intended to free up some storage capacity.
The Drift River terminal, on the western shore of Cook Inlet, is operated by Cook Inlet Pipe Line, which is owned by Chevron and Pacific Energy Resources.
The terminal had been closed since 22 March, when Redoubt began erupting. Chevron, which operates the offshore Granite Point, Trading Bay and McArthur River oil fields, has since struggled with storage space.
The company cut production at the mature fields in response to the volcano problems, and a week ago shut down two of its platforms.
Unlike Chevron, Pacific Energy Resources has not reduced Cook Inlet oil production because it has adequate alternative storage.
