Extract from chart in London Times (print edition), 14 Jan 2003

"Forties, the largest oilfield discovered in the UK North Sea, is to be sold by BP in a deal that marks a watershed in Britain’s declining offshore oil industry... Discovered in October 1970 by the Sea Quest drilling platform, production was inaugurated five years later by the Queen. The field rapidly came to symbolise Britain’s North Sea oil boom. Within three years, Forties was pumping 500,000 barrels per day down a 170-kilometre pipeline to the company’s refinery at Grangemouth in Scotland. Forties has delivered 2.5 billion barrels of oil over three decades but today its produces little more than 45,000 bpd"
