Likewise, international oil companies sell most of their oil in dollars, but they operate in various countries and pay some of their costs in local currencies. Any change in the value of the dollar therefore affects their cost structure and profitability.
同样的，虽然国际石油公司卖出的大部分石油都是以美元计价的，但是他们在不同的国家经营并且用当地货币支付一些支出。任何美元价格的变动都会影响到他们的成本结构和盈利能力，从而进一步影响他们在勘探、研发和维护方面的再投资，
