  • Country: United Kingdom
  • Location: North Sea
  • Production start: 1975
  • Partners:
  • Type: Oil
  • Estimated Reserves: At year-end 2010, Apache had total estimated proved reserves of 155 million barrels of crude oil

  • Forties is one of the oldest and largest oil fields in the UK
  • The field consists of a complex of platforms
    • The FA, FB, FC & FD Platforms are all Large Steel Manned Platforms
    • The FE & Unity Riser Platforms are small steel unmanned platforms
  • Oil is transported onshore by the Forties Pipeline System, which was the UK's first offshore pipeline
  • A number of satellite fields are tied into Forties, including the Bacchus Oil Field and the Maule Oil Field
  • The field is being redeveloped with the addition of the Forties Alpha Satellite Platform (FASP)


  • Laing Offshore: Forties FA & FB Platforms
  • Highlands Fabricators: Forties FC & FD Platforms
  • Brown & Root: Forties Bravo Accommodation block
  • William Press/Penn Baudwin: Construction of Modules
  • AMEC: Project management, engineering and procurement for the design and implementation of brownfield modifications to the Forties Alpha platform

  • 1970 - The Forties Oil Field is discovered by BP
  • 1975 - UK government approval granted
  • 1975 - First oil was produced
  • 1979 - Production form the Forties Field, peaked at 500,000 barrels a day - representing about 25% of UK oil demand at the time
  • 2003 - Apache acquired an approximate 97-percent working interest in the Forties field.
  • 2010 - AMEC chosen to undertake project management, engineering and procurement for the design and implementation of brownfield modifications to the Forties Alpha platform
  • 2012 - Apache announced that the jacket for the Forties Alpha Satellite Platform (FASP) had arrived at the Forties Field


  • The field originally held well over 500 billion litres of oil in its sandy reservoir rock. This rock was deposited as a submarine fan sediment 55 million years ago (F37 and 38).
  • At Forties Field, these sandy layers have draped and sagged across a 'hump' in the underlying rocks. The Main Sand reservoir is composed mostly of sandy sediment deposited as a submarine fan, while much of the separate Charlie Sand accumulated within feeder channels of sand flowing across the sea floor.
  • Oil has migrated upwards from Kimmeridge Clay source rock within the buried rift valley, and has then travelled along the sand layers. Some of the migrating oil has then been trapped within the dome-shaped beds of sandstone above the underlying hump.
