美国原油库存一周骤降855.7万桶至4.156亿桶，为2月以来最大降幅；分析师原预期增加10万桶
华盛顿——美国能源信息署（EIA）10月15日发布的周度数据显示，截至10月9日的一周，美国商业原油库存（不含战略石油储备）减少855.7万桶，降至4.156亿桶，较上年同期时点的五年平均水平低约3%。据《华尔街日报》报道，其调查的分析师原预期库存增加10万桶。据彭博社报道，这是今年2月以来最大单周降幅，部分原因是飓风「以赛亚斯」（Isaias）导致墨西哥湾海上平台停产。
战略石油储备库存当周持平于2.83亿桶。纽约商品交易所交割地库欣的原油库存增加190万桶，至2660万桶。
产量与进出口方面，EIA估计当周美国原油产量为日均1370万桶，环比减少日均30万桶。飓风「以赛亚斯」期间，美国墨西哥湾产油商撤离平台，至上周五海上石油产量逾七成停产，本周三前大部分已经恢复。原油进口降至日均600万桶，环比减少日均79.1万桶；出口降至日均460万桶，减少日均19.5万桶。
炼厂方面，开工率由前一周的92.7%升至93.5%，原油加工量为日均1660万桶，环比减少日均13.5万桶。成品油库存方面，汽油库存增加350万桶至2.083亿桶，低于五年平均水平约4%；馏分油（含柴油与取暖油）库存减少250万桶，低于五年平均水平约12%。商业石油总库存当周减少1340万桶。
数据公布后，纽约市场原油期货周四上涨：西德克萨斯中质原油（WTI）11月合约结算价涨3.03%至每桶97.97美元，布伦特12月合约结算价跌0.13%至每桶105.92美元。
US Crude Inventories Plunge 8.557 Million Barrels to 415.6 Million, the Biggest Drop Since February; Analysts Had Expected a 100,000-Barrel Build
Washington — U.S. commercial crude oil inventories, excluding the Strategic Petroleum Reserve, fell by 8.557 million barrels in the week ended October 9 to 415.6 million barrels, about 3% below the five-year average for the time of year, the Energy Information Administration reported on October 15. Analysts surveyed by The Wall Street Journal had expected an increase of 100,000 barrels. Bloomberg described it as the biggest weekly decline since February, in part because Hurricane Isaias shut in offshore production in the Gulf.
Oil in the Strategic Petroleum Reserve was unchanged at 283 million barrels. Stocks at Cushing, Oklahoma, the delivery point for the New York Mercantile Exchange, rose by 1.9 million barrels to 26.6 million.
The EIA estimated U.S. crude production at 13.7 million barrels a day, down 300,000 barrels a day from the previous week. Producers evacuated platforms ahead of Hurricane Isaias, with more than 70% of offshore oil output shut in by Friday of that week; most of the production had been restored by Wednesday of this week. Crude imports fell by 791,000 barrels a day to 6.0 million barrels a day, and exports fell by 195,000 barrels a day to 4.6 million barrels a day.
Refinery capacity use rose to 93.5% from 92.7%, with crude inputs averaging 16.6 million barrels a day, down 135,000 barrels a day from the previous week. Gasoline inventories increased by 3.5 million barrels to 208.3 million barrels, about 4% below the five-year average, while distillate stocks fell by 2.5 million barrels, about 12% below the five-year average. Total commercial petroleum inventories fell by 13.4 million barrels on the week.
After the data, crude futures rose in New York on Thursday: the November West Texas Intermediate contract settled up 3.03% at $97.97 a barrel, while the December Brent contract settled down 0.13% at $105.92.
