This, from Steven Kinzer's essay on TomDispatch:
BPs roots lie in the early years of the twentieth century when a wealthy bon vivant named William Knox D'Arcy decided, with encouragement from the British government, to begin looking for oil in Iran. He struck a concession agreement with the dissolute Iranian monarchy, using the proven expedient of bribing the three Iranians negotiating with him.
Under this contract, which he designed, D'Arcy was to own whatever oil he found in Iran and pay the government just 16% of any profits he made -- never allowing any Iranian to review his accounting. After his first strike in 1908, he became sole owner of the entire ocean of oil that lies beneath Iran's soil. No one else was allowed to drill for, refine, extract, or sell “Iranian” oil.
”Fortune brought us a prize from fairyland beyond our wildest dreams,” Winston Churchill, who became First Lord of the Admiralty in 1911, wrote later. “Mastery itself was the prize of the venture.”
Soon afterward, the British government bought the D'Arcy concession, which it named the Anglo-Persian Oil Company. It then built the world's biggest refinery at the port of Abadan on the Persian Gulf. From the 1920s into the 1940s, Britain's standard of living was supported by oil from Iran. British cars, trucks, and buses ran on cheap Iranian oil. Factories throughout Britain were fueled by oil from Iran. The Royal Navy, which projected British power all over the world, powered its ships with Iranian oil.
The oil company re-branded itself as British Petroleum, BP Amoco, and then, in 2000, BP. During its decades in Iran, it had operated as it pleased, with little regard for the interests of local people. This corporate tradition has evidently remained strong.
Deep in the recesses of the BP headquarters in St James's, City of Westminster, London, there is a small, secret chapel dedicated to William Knox D'Arcy, where aspiring executives of the company perform strange private rituals before advancing another stage in their careers.
