Английская Википедия:Gullfaks oil field
Gullfaks is an oil and gas field in the Norwegian sector of the North Sea operated by Equinor. It was discovered in 1978, in block 34/10, at a water depth of 130-230 meters.[1] The initial recoverable reserve is Шаблон:Convert, and the remaining recoverable reserve in 2004 is Шаблон:Convert. This oil field reached peak production in 2001 at Шаблон:Convert. It has satellite fields Gullfaks South, Rimfaks, Skinfaks and Gullveig.[2]
Platforms
The project consists of three production platforms Gullfaks A (1986), Gullfaks B (1988), and Gullfaks C (1989).[1] Gullfaks C sits Шаблон:Convert below the waterline and the height of the total structure measured from the sea floor Шаблон:Convert,[3] making it taller than the Eiffel Tower. Gullfaks C holds the record [4] of the heaviest object that has ever been moved to another position, relative to the surface of the Earth with a total displacement between 1.4 and 1.5 million tons.[5] The platform produces Шаблон:Convert of oil. The Tordis field, which is located Шаблон:Convert south east of Gullfaks C, has a subsea separation manifold installed in 2007 which is tied-back to the existing Gullfaks infrastructure.[6][2]

Incidents
Between November 2009 and May 2010 a well being drilled from Gullfaks C experienced multiple well control incidents which were investigated by Petroleum Safety Authority Norway and summarized in a report released on 19 November 2010. The report stated that only chance prevented the final and most serious incident on 19 May 2010 from becoming a full-scale disaster.[8]
Geology
The reservoir consists of delta sandstones from the Middle Jurassic Brent Group, shallow-marine Lower Jurassic Cook Formation sandstones, and the fluvial-channel and delta-plain Lower Jurassic Statfjord Formation.[1]
