It is transported through a network of more than 45,000 kilometres of pipeline to terminals onshore.1
The oil then enters the globally traded crude market and some of it comes back to the UK as refined products. These include the petrol we put in our cars; aviation and marine fuel; lubricants such as engine oils; a whole range of chemicals and plastics; and bitumen for road surfaces.
Gas is either processed on the platforms offshore or transported through pipelines to one of our three plants. Together Shell’s gas plants at St Fergus, Mossmoran and Bacton can process up to 35% of UK gas demand.
There are a large number of pipeline networks across the North Sea. One of the most important is the SEGAL (Shell Esso Gas and Associated Liquids) system that was built in 1982. This was originally built to handle gas production from the Brent field and is now used by a range of operators. This gas is piped to the St. Fergus gas terminal.
The gas we produce comes in two forms, wet and dry gas. Dry gas does not need much processing but wet gas contains a range of other liquids which can be processed and used in a range of chemicals. Much of this wet gas comes through another important pipeline system known as FLAGS (Far North Liquids and Associated Gas system). The liquids are extracted from the gas at the St Fergus terminal and then transported to our plant at Mossmorran, where they are then processed further so they can be used in chemical products.
