Norpipe is a subsea oil and natural gas pipelines system in the North Sea. It supplies oil from the Norwegian Ekofisk and associated fields in the North Sea to the United Kingdom and natural gas to Germany.
The Forties pipeline system (FPS) is a major pipeline transport network in the North Sea. It is owned and operated by Ineos and carries 30% of the UK's oil, or about 550 thousand barrels per day of oil per day, to shore. It carries liquids production from 85 fields in the North Sea and several Norwegian fields on behalf of around 40 companies. The system has a capacity of 575,000 barrels of oil a day.
The oil and gas industry plays a central role in the economy of the United Kingdom. Oil and gas account for more than three-quarters of the UK's total primary energy needs. Oil provides 97 per cent of the fuel for transport, and gas is a key fuel for heating and electricity generation. Transport, heating and electricity each account for about one-third of the UK's primary energy needs. Oil and gas are also major feedstocks for the petrochemicals industries producing pharmaceuticals, plastics, cosmetics and domestic appliances.
The Hutton oil field, located on the UK continental shelf, was the location for the first ever production Tension Leg Platform (TLP).
Gorm is a natural gas and oilfield in the Danish Sector of North Sea. It was discovered in 1971 and is the largest oilfield exploited by Denmark. The production infrastructure consists of five bridge-linked platforms and is operated by BlueNord. The facilities include two wellhead platforms and several processing platforms. The Rolf and Dagmar fields are satellites to Gorm.
Gannet is an oil and gas field located in the United Kingdom's continental shelf in the North Sea. It is 180 km (110 mi) east of Aberdeen, and the water depth at the Gannet offshore installation is 95 m (312 ft). The field is located in Blocks 22/21, 22/25, 22/26 and 21/30. It is half-owned by Royal Dutch Shell (50%) and partly by ExxonMobil (50%) and has been operated by Shell UK Ltd since ‘first oil’ in November 1993. The Gannet A installation is the host platform for subsea tiebacks designated Gannet B to G. Like most Shell fields in the central and northern North Sea the field is named after a sea bird the gannet.
The Murchison oil field is located in the northern North Sea in the East Shetland Basin on the UK Continental Shelf. The field is situated 150 km north-east of Shetland and straddles the UK/Norwegian median line. It lies in UK Block 211/19 and extends into Norwegian Block 33/9. The field is named after the Scottish geologist Sir Roderick Impey Murchison (1792–1871). Recoverable reserves were estimated to be 340 million barrels of oil out of a total oil-in-place of 790 million barrels. The field was developed through a large steel jacket platform standing in 156 m of water. The peak production rate was 150,383 barrels of oil per day in December 1982. Oil production was supported by gas and water injection. Production ceased in 2014 and the platform was removed in 2017.
The L4-L7 gas fields are significant natural gas producing fields in the Netherlands sectors L4 and L7 of the North Sea. They are operationally one complex which started producing gas from the L7 main platform hub in 1977 and was still partly operational in 2021.
The Beryl oil field is a major crude oil production field in the UK sector of the northern North Sea, 335 km north east of Aberdeen. Production of oil started in 1976 and the field is still producing oil and gas (2021).
The K13 gas fields were major natural gas producing fields in the Netherlands sector of the North Sea, about 130 km west of Den Helder. The fields started producing gas in 1975 but are no longer operational except for one installation used as a riser platform.
The Clipper gas field is a major natural gas reservoir and gas production facility in the UK sector of the southern North Sea. The field is located about 73 km north-north-east of Bacton, Norfolk; the Clipper production facility has operated since 1990.
Halfdan is a significant oil and gas field in the south-western part of the Danish sector of the southern North Sea. The field has been in production since 1999. The Sif and Igor fields are satellites to Hallfdan.
The Edda oil and gas field was a crude oil and associated gas production field in the Norwegian sector of the central North Sea. Production of oil and gas started in 1979, peak oil and gas was achieved in 1980. Production ceased in 1998 and the installation and field infrastructure were dismantled in 2012.
The Cod oil gas and condensate field was a gas and associated natural gas liquids (NGL) production field in the Norwegian sector of the central North Sea. Production of oil and gas started in 1977, peak gas and NGL was achieved in 1980. Production ceased in 1998 and the field installation was dismantled in 2013.
The Odin gas field was a gas producing field in the Norwegian sector of the central North Sea. Production of gas started in October 1984, the peak gas production of 360 mmcfd was achieved in 1985. Production ceased in 1994 and the field installation was dismantled in 1997.
The Eldfisk oil and gas field is a crude oil and gas producing field in the Norwegian sector of the central North Sea. Production of oil and gas started in 1979 and peak oil and gas production was achieved in 1980. The facilities have been extended and are still operational.
The Embla oil and gas field is a high-pressure high-temperature (HPHT) crude oil and associated gas producing field in the Norwegian sector of the central North Sea. Production of oil and gas started in 1993, peak oil and gas was achieved in 1994, and the field is still operational.
The Tor oil field is a crude oil and associated gas producing field in the Norwegian sector of the central North Sea. Production of oil and gas started in 1978 and peak oil and gas was achieved in 1979. The field was shut down in 2015 and, following the completion of new wells, started up again in 2020.
