North Sea oil is a mixture of hydrocarbons, comprising liquid petroleum and natural gas, produced from petroleum reservoirs beneath the North Sea.
A floating production storage and offloading (FPSO) unit is a floating vessel used by the offshore oil and gas industry for the production and processing of hydrocarbons, and for the storage of oil. An FPSO vessel is designed to receive hydrocarbons produced by itself or from nearby platforms or subsea template, process them, and store oil until it can be offloaded onto a tanker or, less frequently, transported through a pipeline. FPSOs are preferred in frontier offshore regions as they are easy to install, and do not require a local pipeline infrastructure to export oil. FPSOs can be a conversion of an oil tanker or can be a vessel built specially for the application. A vessel used only to store oil is referred to as a floating storage and offloading (FSO) vessel.
Wytch Farm is an oil field and processing facility in the Purbeck district of Dorset, England. It is the largest onshore oil field in western Europe. The facility, taken over by Perenco in 2011, was previously operated by BP. It is located in a coniferous forest on Wytch Heath on the southern shore of Poole Harbour, two miles (3.2 km) north of Corfe Castle. Oil and natural gas (methane) are both exported by pipeline; liquefied petroleum gas is exported by road tanker.
Ekofisk is an oil field in block 2/4 of the Norwegian sector of the North Sea about 320 km (200 mi) southwest of Stavanger. Discovered in 1969 by Phillips Petroleum Company, it remains one of the most important oil fields in the North Sea. This was the first discovery of oil after the drilling of over 200 exploration wells in the North Sea "triggered" by the Groningen gas field discovery. In 1971, Phillips started producing directly to tankers from four subsea wells. Oil production is planned to continue until at least 2050.
A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations.
The Dunlin oilfield is situated 195 km northeast of Lerwick, Shetland, Scotland, in block number 211/23a and 211/24a. It was originally operated by Shell but was sold in 2008 and is now operated by Fairfield Energy and partners MCX.
Kashagan Field is an offshore oil field in Kazakhstan's zone of the Caspian Sea. The field, discovered in 2000, is located in the northern part of the Caspian Sea close to Atyrau and is considered the world's largest discovery in the last 30 years, combined with the Tengiz Field. When discovered, it was the second largest oil field in the world.
The Clair oilfield is an offshore oil field in Scottish territorial waters 75 kilometres (47 mi) west of Shetland in water depths of up to 140 metres (460 ft). It extends over an area of some 220 square kilometres (85 sq mi), covering five licence blocks.
Azeri–Chirag–Gunashli or Azeri–Chirag–Deepwater Gunashli is a complex of oil fields in the Caspian Sea, about 120 kilometres (75 mi) off the coast of Azerbaijan. It consist of Azeri and Chirag oil fields, and the deepwater portion of the Gunashli oil field. An overall estimated area of the development is 432.4 square kilometres (167.0 sq mi). It is developed by the Azerbaijan International Operating Company, a consortium of international oil companies, and operated by BP on behalf of the consortium. The ACG fields have estimated recoverable reserves of about 5 to 6 billion barrels of petroleum. As of the end of 2005, the production rate from eight pre-drilled wells at the platform was approximately 240,000 barrels per day (38,000 m3/d).
This is a list of oil and gas fields operated by BP.
The Forties Oil Field is the largest oil field in the North Sea, 110 miles east of Aberdeen. It was discovered in 1970 and first produced oil in 1975 under ownership of British Petroleum, now called BP.
The Miller oilfield is a deep reservoir under the North Sea, 240 kilometres north-east of Peterhead in UKCS Blocks 16/7b and 16/8b. It was discovered in 1983 by BP in a water depth of 100 metres. Production from Miller field started in June 1992, and plateau production was from late 1992 to 1997 at rates of up to 150,000 barrels (24,000 m3) of oil and 255 million cu ft (7.2 million m3) of gas per day at standard conditions. Miller produced some 345 million barrels (54,900,000 m3) of oil during its lifetime. The field is named after Hugh Miller who contributed to Scottish geology in the early nineteenth century.
Grane is an offshore oil field in the North Sea located 185 km (115 mi) west of the city of Haugesund on the western coast of Norway. It is Norway's first heavy crude oil production field and Statoil's largest heavy oil field in the Norwegian continental shelf. The oil from the field, located in Block 25/11 is transported to Sture terminal via Grane oil pipeline. The injection gas is imported to Grane oil field from the Heimdal, located just north the field.
Skirne which also includes the Byggve deposit is an offshore gas field in the North Sea located 24 kilometres (15 mi) east of the Heimdal gas field and 140 kilometres (87 mi) from Stavanger, Norway. The depth of the water in the field area is 120 metres (390 ft). Both Skirne and Byggve are considered satellites to Heimdal field and are connected to it by subsea pipelines. TotalFinaElf which is the operator had received the approval from Norwegian Ministry of Petroleum and Energy for development of the fields in 2002. The company holds 40% interest in the project. Other stakeholders are Petoro and Centrica. Both Skirne and Byggve have an estimated 230 billion cubic feet of natural gas and about 10 million barrels of condensate, combined.
Oselvar is a since April 2018 abandoned subsea oil field located 250 km (160 mi) southwest of Stavanger in the southern Norwegian section of the North Sea, close to the British border. Oselvar was discovered in 1991. The field is located at 23 kilometres (14 mi) distance from the Ula field to which it was tied back. The original estimated reserves at Oselvar were 38 million barrels of oil and 4 billion cubic metres of natural gas. The water depth at location is 72 metres (236 ft). The Oselvar field installations shall be decommissioned by the end of 2022.
Gyda is an offshore oil field located in the southern Norwegian section of North Sea along with Ula, Tambar and Tambar East fields making up the UGT area, usually attributed to DONG Energy's main areas of exploration and production activity. The Gyda field was discovered in 1980 and started producing on June 21, 1990. The field contains confirmed 39.6 million m3 of oil and 6.6 billion cubic meter of natural gas.
Tambar is an offshore oil field located in the southern Norwegian section of North Sea along with Ula and Gyda fields making up the UGT area, usually attributed to DONG Energy's main areas of exploration and production activity. The Ula field was discovered in 1983 and came online in 2001. Tambar was discovered in 1983 and became operational in July 2001. It contains confirmed 46.9 million m3 of oil.
Blane is an offshore oil field located in the southern Norwegian and northern British sectors of North Sea. The Blane facilities are located on the British continental shelf and are tied to the Ula field which is located 34 km (21 mi) to the northeast via subsea pipeline. The field was discovered in 1989 and produces high quality oil.
The Johan Sverdrup oil field is an oil field in the North Sea, about 140 kilometres (87 mi) west of Stavanger, Norway. The field lies in two different production licenses and consists of two different discoveries called Avaldsnes and Aldous Major South. When it was revealed that these discoveries constituted one single field, it was renamed Johan Sverdrup after the father of Norwegian parliamentarism. The field has not yet been unitized between production licenses 501, 501B, and 265. Johan Sverdrup is expected to hold 1.9–3.0 billion barrels of oil. According to Statoil, the field is in 110 to 120 metres water depth, and the reservoir is at 1900 meters depth.
