EIA Petroleum Status Report
Highlight
Crude oil inventories fell 3.0 million barrels in the September 30 week to 502.7 million barrels. Though it was the fifth weekly decline in a row and whittled the year-on-year gain down 1.4 percentage points to 8.4 percent, some market participants had anticipated a bigger drop after the American Petroleum Institute said Tuesday the weekly drawdown would be 7.6 million barrels. Product inventories were mixed but also down on a net basis, with gasoline up 0.2 million barrels to 227.4 million barrels for a 1.6 percent annual gain, while distillate fuels were down 2.4 million barrels to 160.7 million, 7.8 percent higher than a year ago.
Refineries operated at 88.3 percent capacity last week, down from 90.1 percent in the prior week, but production increased, averaging 10.0 million barrels per day for gasoline and 4.7 million barrels per day for distillate fuel.
On the demand side, total product supplied over the last four weeks averaged 19.9 million barrels per day, up by 3.0 percent from the same period a year ago. Supplied gasoline averaged 9.3 million barrels daily, up 3.2 percent from the year ago level, while supplied distillate fuel averaged 3.6 million barrels, down by 8.9 percent.
WTI, which had risen to the highest level since June in recent sessions on news that OPEC would cut production and maintain it between 32.5 million to 33.0 million barrels per day, fell about 25 cents to $49.25 per barrel immediately after the release of the EIA report, but quickly recovered and rose to new highs for the day at around $49.87 per barrel.
原油庫存在9月30日下跌300萬桶，達到50270萬桶。雖然這是連續第五個週下跌，削減了1.4個百分點的8.4％，但有些市場參與者預計在美國石油協會星期二公布每週將減產760萬桶後會有一波跌勢。產品庫存混合，但也基於淨額，汽油增加20萬桶至2.274億桶，年增長1.6％，而餾出燃料則下降240萬桶至1.670億，比去年同期高出7.8個百分點。
煉油廠上週的產能為88.3％，低於前一周的90.1％，但產量增加，平均每天汽油為1,000萬桶，餾分燃料為每日470萬桶。
在需求方面，過去四個星期的總產量平均為每天1990萬桶，比去年同期增長3.0％。供應汽油平均每天930萬桶，比上年同期增長3.2％，而供應的餾分燃料平均為360萬桶，下降8.9％。
WTI上升至6月以來的最高水平，原因是近期因OPEC將進行減產，並保持每日出3250萬至3300萬桶，當一發布的EIA報告時石油價格下降約25美分至每桶49.25美元，但迅速恢復併升至新高，為 當日49.87美元左右。
Definition
The Energy Information Administration (EIA) provides weekly information on petroleum inventories in the U.S., whether. produced here or abroad. The level of inventories helps determine prices for petroleum products.
能源資料管理局（EIA）提供關於每周美國或國際石油庫存的訊息。存貨的水平有助於確定石油產品的價格。
EIA原油庫存（不含石油戰略儲備）由美國能源信息署【（能源情報署）簡稱EIA，隸屬美國能源部，屬官方機構】統計公佈（該數據不包括戰略石油儲備）。現貨原油市場的交易員和國際權威的能源諮詢機構都是採用EIA的庫存數據[1]。該數據每週公佈一次【週三22時三十（冬令時23點30分）公佈】，此數據主要顯示了美國當週原油庫存數量，對於瀝青及原油提煉品（燃油，柴油等）有較大影響。油市，匯市以及貴金屬市場都會造成一定的影響，投資者需密切關注。
公佈時間 : 週三晚間10:30（冬令時11:30）
Why Investors Care
Petroleum product prices are determined by supply and demand - just like any other good and service. During periods of strong economic growth, one would expect demand to be robust. If inventories are low, this will lead to increases in crude oil prices - or price increases for a wide variety of petroleum products such as gasoline or heating oil. If inventories are high and rising in a period of strong demand, prices may not need to increase at all, or as much. During a period of sluggish economic activity, demand for crude oil may not be as strong. If inventories are rising, this may push down oil prices.
Crude oil is an important commodity in the global market. Prices fluctuate depending on supply and demand conditions in the world. Since oil is such an important part of the economy, it can also help determine the direction of inflation. In the U.S., consumer prices have moderated whenever oil prices have fallen, but have accelerated when oil prices have risen.
石油產品價格由供需決定。在經濟增長強勁期間，人們將預期需求是強勁的。如果庫存量低，這將導致原油價格上漲 - 或者對於各種石油產品如汽油或加熱油的價格上漲。如果庫存量高並且在需求旺盛的時期上升，價格可能根本不需要增加或增加。在經濟活動不振的時期，原油需求可能不會那麼強勁。如果庫存增加，這可能推低石油價格。
原油是全球市場的重要商品。價格波動取決於世界的供需情況。由於石油是經濟的重要組成部分，它也有助於確定通貨膨脹的方向。在美國，當石油價格下跌時，消費價格緩和，但是當石油價格上漲時，消費價格加速。
