The Argyll oil field is located in Blocks 30/24 and 30/25 of the UK North Sea continental shelf.

[1] The geology of the Duncan field (discovered in 1980) is similar to Argyll comprising two Jurassic reservoirs.

[3] The Argyll field was initially developed by Hamilton Brothers using a converted semisubmersible production and accommodation vessel (Transworld 58).

[1] The first oil from the field was loaded into the tanker Theogennitor and offloaded at the BP refinery at the Isle of Grain Kent.

[5] They renamed the field Ardmore and redeveloped it with the Rowan Gorilla VII mobile drilling and production jack-up unit.

[7] Oil was sent to two single anchor leg mooring buoys located 1.5 km from Ardmore and was loaded into the two shuttle tankers.

[2] Tuscan Energy and Acorn Oil and Gas produced 5.2 million bbl (830 thousand m3) between October 2003 and June 2005.

[3] After Ardmore ceased production in June 2005 the wells were plugged and the jack-up and loading facilities were removed from the field.

Both of the fields were redeveloped as a joint facility based on the EnQuest Producer (formerly Uisge Gorm) Floating Production, Storage and Offloading (FPSO) vessel.

From the latter oil flowed to the electrostatic dehydrator prior to cooling and transfer to the vessel's storage tanks.
