中国石化新闻网 据普氏能源资讯6月12日报道，英国石油公司（BP）最新估计，沙特阿拉伯已探明的石油储量比此前预估的近3000亿桶高出11%。此前，这个全球最大的石油出口国提供了其庞大的石油和天然气储量构成的新细节。
BP在其最新的年度统计报告中称，截止2018年底，已探明原油和液化天然气2977亿桶，储量比前一年增加了17亿桶。
但BP首席经济学家斯宾塞•戴尔（Spencer Dale）表示，沙特的储量数据比去年高出约300亿桶，反映了沙特石油巨头沙特阿美石油公司（Saudi Aramco）对其天然气液体（或称“含油气”）分类的新细节。
沙特阿美最新的年度报告估计，截至2017年底，该国的天然气凝析油储量为351亿桶。
戴尔在伦敦对记者表示：“我们使用了沙特阿美的数据，他们已经开始公布他们的天然气储量。之前，我们认为这些天然气凝析油大部分都在天然气储量中。”他指出，沙特阿美最近报告的天然气储量有所下降。
根据阿美石油公司的最新数据，2017年，沙特阿拉伯已探明的天然气储量为369.3亿桶石油当量，低于2016年的527.9亿桶石油当量。
BP最新的统计评估显示，2018年底，沙特阿拉伯已探明的天然气储量为5.9万亿立方米，低于2017年的8万亿立方米。

Saudi Arabia's oil reserves jump 30 billion barrels after data review: BP
Saudi Arabia's proved oil reserves are 11% higher than previously thought at close to 300 billion barrels, according to the latest estimates by BP, after the world's top oil exporter provided new details on the make-up of its giant oil and gas reserves.
Saudi Arabia held 297.7 billion barrels of proved crude and natural gas liquids at the end of 2018, with reserves climbing by 1.7 billion barrels on the year before, BP said in its latest annual Statistical Review.
But the Saudi reserve figures are some 30 billion barrels higher than year-ago levels, reflecting new detail from state-oil giant Saudi Aramco on the classification of its natural gas liquids, or "wet gas" as liquid oil, BP's chief economist Spencer Dale said.
Aramco's latest annual report estimates that the country's reserves of NGLs -- light hydrocarbon liquids separated from raw natural gas flows -- stood at 35.1 billion barrels at the end of 2017.
"We use Saudi Aramco data and they have started to break out their NGLs," Dale told reporters in London. "Before, we think most of those NGLs were in their gas reserves," he said, noting that Aramco's latest reported gas reserves have recently fallen.
According to Aramco's latest figures, Saudi Arabia's proven gas reserves stood at 36.93 billion barrels of oil equivalent in 2017, down from a previously reported oil equivalent figure of 52.79 billion for 2016.
Reflecting the fall, BP's latest Statistical Review now pegs Saudi Arabia proven gas reserves at 5.9 Tcm for the end of 2018, down from 8 Tcm in 2017.
