List of oil and gas fields of the North Sea



This list of oil and gas fields of the North Sea contains links to oil and natural gas reservoirs beneath the North Sea. In terms of the oil industry, "North Sea oil" often refers to a larger geographical set, including areas such as the Norwegian Sea and the UK "Atlantic Margin" (west of Shetland) which are not, strictly speaking, part of the North Sea. The UK list includes facilities in the Irish Sea.

Offshore
The UK continental shelf (UKCS) comprises six geographical and geological oil, gas and condensate regions: Southern North Sea (principally gas fields); Central North Sea (oil, condensate and gas fields); Moray Firth (oil and associated gas fields); Northern North Sea (oil and associated gas fields); West of Shetland (oil and associated gas); and the Irish Sea/Liverpool Bay (oil and gas). The fields and installations in the following list are allocated to regions corresponding to the Oil and Gas Authority's listings.

Installation Identification

Oil and gas field names follow themes chosen by the companies who originally developed them. An offshore installation on the UK Continental Shelf may comprise a single integrated platform or two or more bridge-linked platforms. Installations are identified by a large black-on-yellow sign on the installation. This may give the name of the original or current owner or operator, the field name, and a set of numbers and letters, e.g. Shell/Esso Leman 49/26A. The numbers identify the Quadrant and Block where the installation is located, e.g. 49/26 is in Quadrant 49 Block 26. The first letter is a sequential letter (A, B, C, D, etc.) identifying each installation within a field. For installations in the Southern North Sea the second and subsequent letters may designate a platform's function, e.g. the Leman 49/26A complex comprises four bridge-linked platforms 49/26AP (Production), 49/26AD1 (Drilling 1), 49/26AD2 (Drilling 2), and 49/26AK (Compression). Common designations are: Note: Drilling refers to the original function of the platform to support well drilling operations. No Southern North Sea installation has permanent drilling facilities.

On some installations the letters simply provide a unique two letter identity, e.g.Tethys TN, Viscount VO.

Southern North Sea gas fields
The Southern North Sea (SNS) comprises gas (plus associated condensate) fields. Themed field names comprise groups of fields that are geographically, operationally or commercially linked. Names are based on: A full listing of UK Southern North Sea gas fields is given in the table below.
 * Geographical location (Leman, Sole Pit, etc.)
 * Personal names (e.g. Audrey, Sean)
 * ‘Lost’ east coast villages (Ravenspurn, Newsham, etc.)
 * Arthurian legend (e.g. Camelot, Excalibur, Guinevere)
 * Planets and moons (Jupiter, Ganymede, etc.)
 * Gemstones (Amethyst, Topaz)
 * Scientists and inventors (e.g. Murdoch, Davy)
 * Rivers (Tyne, Waveney, etc.)
 * Sailing vessels (e.g. Ketch, schooner)
 * Aircraft (Vulcan, Valiant, Victor, etc.)

Offshore

 * Nothing published, but the idea is not inconceivable on the ridges extending towards Iceland from the Faroes and the East Greenland Coast

Onshore

 * No prospects reported, though sediments analogous to the Mesozoic and Caenozoic deposits of the North Sea are known, so there is appreciable interest. Development would be formidably difficult, technically, logistically and politically.

Offshore

 * A recent conference on hydrocarbon prospects in arctic Russia (Geological Society, London; February 2006) had several speakers mention major gas prospectivity on the East Greenland coast, but they cited no sources. A conference volume was due towards the end of 2006, which may elaborate.

Onshore

 * No significant prospects or potential

Offshore
