Perdido is the world’s deepest offshore oil drilling and production platform. Moored in 2,450 metres (8,000 feet) of water in the Gulf of Mexico, this spar gathers, processes and exports produced hydrocarbons within a 48-kilometre (30-mile) radius.
At peak production, Perdido processes 100,000 barrels of oil equivalent a day, and 200 million cubic feet of gas.
The 170-metre (555-foot) cylindrical spar was secured to the sea floor and Shell completed the installation of the drilling and production platform on top of it. Around 270 staff living on the platform and an adjacent floating hotel, or flotel, completed the commissioning and hook-up required to produce first oil.
There are 22 direct vertical access wells from the spar, with an additional 13 tiebacks from subsea completions. The Perdido hull is nearly as tall as the Eiffel Tower and weighs the same as 10,000 large family cars.
The Noble Clyde Boudreaux platform drilled the production wells. In November 2011, FMC Technologies, Inc. announced that its enhanced vertical deepwater tree (EVDT) system set a new world deepwater completion record of 9,627 feet at the Shell-operated Tobago Field.
