<span class="mw-page-title-main">Brent oilfield</span> Former oilfield in the North Sea

The Brent field was an oil and gas field located in the East Shetland Basin of the North Sea, 186 kilometres (116 mi) north-east of Lerwick in the Shetland Islands, Scotland, at a water depth of 140 metres (460 ft). The field operated by Shell UK Limited was discovered in 1971 and was once one of the most productive parts of the UK's offshore assets but has reached the stage where production is no longer economically viable. Decommissioning of the Brent field is complete with the exception of Brent C, which is producing from another field. The discovery well 211/26-1 was drilled in 1971 by the semi-submersible drilling rig "Staflo". This was a major surprise at the time as the nearest land in Scotland and Norway is composed of granite and other non reservoir metamorphic rocks.

The Ninian Central Platform is an oil platform in the North Sea. When constructed in Loch Kishorn, Scotland in 1978 the 600,000 tonne platform was the world's largest man-made movable object before being towed to its current position and sunk to the sea floor.

<span class="mw-page-title-main">Oil and gas industry in the United Kingdom</span>

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.

Brage is an offshore oil field in the North Sea located 120 km (75 mi) northwest of the city of Bergen on the western coast of Norway and 13 km (8.1 mi) east of Oseberg Field Center. The field also contains gas. The water depth at the location is 140 metres (460 ft). The field was developed with a fixed integrated production, drilling and accommodation facility The oil from the field is pumped through a pipeline to Oseberg A facility from where it is transported to Sture terminal via Oseberg Transport System. The gas from the field is exported through Statpipe system to Kårstø. It is estimated that Brage may hold up to 20,000,000 barrels (3,200,000 m3) to 25,000,000 barrels (4,000,000 m3) of recoverable oil.

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.
