US oil reserves surpass those of Saudi Arabia and Russia
美国石油储量首次超过沙特、俄罗斯
广州石油翻译公司：咨询公司Rystad Energy的最新研究显示，美国石油储量总计2640亿桶，其中一半以上是非常规的页岩油。
The US holds more oil reserves than Saudi Arabia and Russia, the first time it has surpassed those held by the world’s biggest exporting nations, according to a new study.
一项新研究显示，美国石油储量已高于沙特阿拉伯、俄罗斯，这是美国石油储量首次超越世界最大的石油输出国。广州石油翻译公司。
Rystad Energy estimates recoverable oil in the US from existing fields, discoveries and yet undiscovered areas amounts to 264bn barrels. The figure surpasses Saudi Arabia’s 212bn and Russia’s 256bn in reserves.
咨询公司Rystad Energy估计，美国既有油田、已发现和尚未发现的可采石油总计2640亿桶。这一数字超过了沙特和俄罗斯的石油储量，后两者的储量分别为2120亿桶和2560亿桶。
The analysis of 60,000 fields worldwide,shows total global oil reserves at 2.1tn barrels. This is 70 times the current production rate of about 30bn barrels of crude oil a year, Rystad Energy said on Monday.
这项对全球范围内6万处油田的分析显示，全球石油总储量为2.1万亿桶。Rystad Energy周一表示，这一数字70倍于当前的原油年产量，后者约为300亿桶。
Conventional oil producers, such as Saudi Arabia, have traditionally used their huge resource riches to wield power globally, particularly among big consumer countries such as the US.
沙特等常规石油生产国一直利用其巨大的资源财富在全球发挥影响力，尤其是对美国等石油消费大国施加影响。广州石油翻译公司。
This relationship has been disrupted in recent years by hydraulic fracturing and other new technologies that have helped the US unlock vast reserves and enabled it to become more energy independent.
近些年来，这种关系已被水力压裂等新技术颠覆，这些新技术帮助美国“解锁”了巨大的储量，令其在能源方面能够更加独立。
More than half of the US’s remaining oil reserves are in unconventional shale oil, Rystad Energy data show.
Rystad Energy数据显示，美国剩余的石油储量中，一半以上是非常规的页岩油。
Other global oil reserves data, like the closely watched BP Statistical Review that is based on official reporting from national authorities, show the US still ranks behind countries such as Saudi Arabia, Russia, Canada, Iraq, Venezuela and Kuwait.
其他全球性石油储量数据——比如根据各国政府部门的官方报告汇编而成的、受到密切关注的《BP世界能源统计年鉴》(BP Statistical Review)——显示，美国的石油储量仍落后于沙特、俄罗斯、加拿大、伊拉克、委内瑞拉和科威特。广州石油翻译公司。
While the reserves numbers are crucial, the cost of production is just as vital, said Richard Mallinson at London-based consultancy Energy Aspects.
伦敦咨询公司Energy Aspects的查德•马林森(Richard Mallinson)表示，尽管石油储量数据很关键，但生产成本同样重要。
Although US shale oil has become more economical to produce — costs have halved over the past two years to below $40 a barrel in some instances — Saudi Arabia and other Middle Eastern producers still pump oil for less than $10 a barrel.
虽然美国页岩油生产的经济性已经提高——一些例子显示，生产成本在过去两年里已经减半、降至每桶40美元以下——但沙特和其他中东产油国的石油开采成本依然不到每桶10美元。
