 The majority of the largest oil fields in the UK sector of the North Sea were found in the waters to the north and east of the Scottish mainland, with the more northerly fields found to the east of the Orkney and Shetland islands.Aberdeen became the centre of Britain's North Sea oil industry, with many oil terminals such as that of Sullom Voe in Shetland and Flotta in Orkney and at Cruden Bay and St Fergus on the north east coast of Scotland, being built to support the North Sea oil industry.In the early 1970s, there was a great deal of economic turbulence with the 1973 oil price shock caused by the Yom Kippur War, resulting in rising inflation coupled with high unemployment, recession (also known as stagflation) in Scotland and the rest of the United Kingdom.
