Ula (Norwegian : Ulafeltet) is an offshore oil field located in the southern Norwegian section of North Sea along with Gyda, Tambar and Tambar East fields making up the UGT area, usually attributed to DONG Energy's main areas of exploration and production activity. [2]

Contents

The Ula field was discovered in 1976 and came online in October 1986. [3] It contains confirmed 69.98 million m3 of oil and 2.5 million of NGL. [1]

Ownership

AkerBP is the operator of the field with 80% of interest in the project. AkerBP's partner DONG Energy holds 20% of interest. [3] DONG Energy increased its initial share of 5% to 20% by acquiring Svenska Petroleum's complete share of 15% for US$130 million in 2008. [2]

Production

Ula is located in approximately 70 m (230 ft) of water. The main reservoir stands at 3,345 m (10,974 ft) in the Upper Jurassic Ula Formation. [1] The field has three conventional steel facilities with production, drilling, living quarters. It has 7 production and 2 water injection wells. Current production at Ula field is 10,000 bbl/d. The existing gas process plant was recently extended with a new module, turbine and compressor and has been operative since 2008. The gas from Blane field is injected into the Ula reservoir for production. The gas produced at Ula field is re-injected into the field for increased recovery as well. The field is expected to be abandoned in 2028. [3] The produced oil is then transported by a pipeline to Ekofisk oil field and on to Teesside for refining. [1] In 2009, Aker Solutions was awarded a contract to tieback Ula field to Oselvar field. The work is expected to commence in 2011. [4] Once complete, the oil from DONG-operated Oselvar field which is 24 kilometres (15 mi) from Ula will be pumped to facilities at Ula for processing. [5]

North Sea oil

North Sea oil is a mixture of hydrocarbons, comprising liquid petroleum and natural gas, produced from petroleum reservoirs beneath the North Sea.

Ormen Lange (gas field)

Ormen Lange is a natural gas field on the Norwegian continental shelf. It is situated 120 kilometres (75 mi) northwest of Kristiansund, where seabed depths vary between 800 and 1,100 metres. The field is named after the famous longship Ormen Lange of Olaf Tryggvason, a 10th-century Viking king of Norway.

Wytch Farm

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.

Petroleum reservoir Subsurface pool of hydrocarbons

A petroleum reservoir or oil and gas reservoir is a subsurface pool of hydrocarbons contained in porous or fractured rock formations. Petroleum reservoirs are broadly classified as conventional and unconventional reservoirs. In conventional reservoirs, the naturally occurring hydrocarbons, such as crude oil or natural gas, are trapped by overlying rock formations with lower permeability, while in unconventional reservoirs, the rocks have high porosity and low permeability, which keeps the hydrocarbons trapped in place, therefore not requiring a cap rock. Reservoirs are found using hydrocarbon exploration methods.

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 Offshore oil field in Kazakhstans zone of the Caspian Sea

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

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).

Valhall oil field

Valhall is an oil field in the Norwegian sector of the North Sea. Discovered in 1975, production began in 1982 and is expected to continue until 2050. Valhall is located in 70 metres of water. It produces from chalk in the Tor and Hod Formations of Late Cretaceous age. The reservoir depth is approximately 2 400 metres.

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.
