The Brent field is situated 186km (116 miles) offshore, north-east of Lerwick, Scotland, at a water depth of 140m (460ft), and has four large platforms; Alpha, Bravo, Charlie and Delta.
The Brent field was discovered in 1971. Oil production began in 1975. Then following a £1.2 billion Long-Term Field Development (LTFD) project in the mid 1990s, Brent became predominantly a gas field.
The Brent field has been in service for the UK for more than 35 years. Formerly Shell’s flagship asset in the UK Continental Shelf (UKCS), it is a household name in the North East of Scotland and much of the UK, as well as providing a benchmark for crude oil pricing around the world. Brent has provided employment for thousands of people as well as a wealth of learning for the rest of the North Sea oil and gas industry.
The field supplies oil via the Brent System pipeline to the terminal at Sullom Voe, while gas is piped through the FLAGS (Far North Liquids and Associated Gas System) to St. Fergus on the North East coast of Scotland. The Penguins field is connected to the Brent Charlie platform via a sub-sea pipeline.
Brent has led the way in many technological advances, such as:
- The LTFD project, which is the largest and most comprehensive field redevelopment ever undertaken in the North Sea.
- Process controls methods that ensure Brent Alpha can operate with a small number of personnel.
- Using the latest sub-sea technology to develop the challenging, northern Penguins field.
As Brent continues to produce, it naturally depletes and, over many years of production, has moved from providing some 10% of the UK’s gas consumption to less than 2% today. The flow of oil and gas from Brent has now reached a point at which it is no longer viable to run the Brent Delta platform.
The rest of the field (platforms Brent Alpha, Bravo and Charlie) continues to produce oil and gas although these platforms too will shortly reach their cessation of production.
