Everest gasfield
Encyclopedia
The Everest gasfield is located in the Central North Sea
, 233 kilometres (144.8 mi) east of Aberdeen
, Scotland
. It lies in the United Kingdom Continental Shelf blocks 22/9, 22/10a and 22/14a. The gasfield was discovered by Amoco
in 1982 with first gas
produced in 1993. Until 2009, the field was operated by BP
(formerly Amoco). As a result of assets' swap between BP and BG Group
in 2009, BG Group became the largest stakeholder of field with 80.46% interest and it took over operatorship of the field. Other partners beside of BG Group are Amerada Hess, and Total
. The 1.0134% interest, which was owned by ConocoPhillips
, was acquired by BG Group in 2007.
The field is named after George Everest
. There is a permanent production installation
in the Northern area of the field (located 57.75°N 1.801°W: 288 ft (87.8 m) water depth), containing 11 surface wells
and a flowline connecting to two subsea wells in the Southern area. The North Everest platform, built by Highland Fabricators, is also the location for the starting point of the CATS pipeline
, which relays gas from Everest and a number of others including Lomond and Armada
, to the CATS terminal at Teesside
. The North Everest platform is linked with the unmanned CATS riser platform by a 90 metres (295.3 ft) metal bridge. Condensates and liquids are routed via Forties oilfield
.
Everest contains two main reservoirs: the Palaeocene Forties sandstone and the deeper Paleocene Andrew sandstone. The structure is a 3 way dip closure with a stratigraphic pinchout to the east.
