BP is one of Britain’s biggest companies and one of the world’s largest oil and petrochemicals (石油化工产品) groups.BP owes its origin to one man, William Knox D’Arey, who, shortly after the turn of the twentieth century, invested time, money and labour in the belief that worthwhile deposits of oil could be found in Persia.In the company’s first six decades, its prime focus lay in the Middle East. But from the late 1960s the centre of gravity shifted westwards, towards the USA and Britain itself.However, the BP of today is an international company, having operations in over 70 countries.
