據管道&天然氣雜志網6月22日報道，美國俄克拉荷馬州庫欣儲存中心的原油庫存已升至兩年來的最高水平，因為美國中西部煉油廠的停產抑制了需求，而來自加拿大的原油流量增加了供應。

美國原油期貨交割點庫欣的庫存在今年早些時候下跌后，已連續八周攀升。據分析師表示，海外對美國原油的需求和煉油廠停產的結束應該會扭轉這種局面。

價格期貨集團（Price Futures Group）分析師菲爾·弗林表示，“我們將向海外出口更多(石油)。從整體來看，供應方面仍然緊張”。

根據EIA的數據顯示，中西部地區一連串意外的煉油廠停產增加了庫存。6月9日當周，庫存增至4210萬桶，為2021年6月以來的最高水平。

分析機構IIR Energy高級主管希拉里·史蒂文森(Hillary Stevenson)表示，該公司5月份在美國中部追蹤到57.9萬桶/天的原油停產量，是去年同期25.6萬桶/天停產量的兩倍。

Stevenson補充道，bp和Cenovus Energy Inc.位于俄亥俄州托萊多的日產16萬桶煉油廠以及Phillips 66位于得克薩斯州Borger的日產14.9萬桶煉油廠相繼停產可能導致庫欣庫存增加。

伍德麥肯茲北美原油市場首席分析師約翰·科爾曼（John Coleman）表示，來自加拿大的稍高流量也增加了供應量，恩橋公司Flanagan South管道5月和6月至今的流量也有所增加。

數據分析機構Kpler美洲首席石油分析師Matt Smith表示，加拿大原油可能已被送往庫欣，作為去年發生過火災的托萊多煉廠用以重啟的原料。

US Oil Stocks at Cushing Delivery Hub Hit 2-Year Peak

U.S. crude oil inventories at the Cushing, Oklahoma, storage hub have risen to their highest in two years, as outages at Midwestern refiners crimp demand and higher flows from Canada add to supply.

Stockpiles at Cushing, the delivery point for U.S. crude oil futures, have climbed for eight consecutive weeks after falling earlier this year. Overseas demand for U.S. crude and an end to refinery outages should reverse the build, analysts said.

"We're going to be sending more (oil exported) abroad," said Phil Flynn, an analyst at Price Futures Group. "The supply side continues to remain tight if you look at the big picture."

A spate of unexpected refinery outages in the Midwest have added to the inventories, which rose to 42.1 million barrels in the week to June 9, the highest since June 2021, Energy Information Administration data showed.

IIR Energy was tracking 579,000 barrels per day (bbl/d) of oil offline in May in the central U.S., double the 256,000 bbl/d offline the same month a year ago, said Hillary Stevenson, a senior director at the company.

Outages at BP Plc's and Cenovus Energy Inc.'s 160,000-bbl/d Toledo, Ohio refinery and Phillips 66's 149,000-bbl/d Borger, Texas refinery likely have contributed to higher Cushing stockpiles, Stevenson added.

Slightly higher flows from Canada also added to the supplies, with Enbridge Inc.'s 702,000-bbl/d Flanagan South pipeline showing elevated flows in May and so far in June, said John Coleman, principal analyst for North American crude markets at Wood Mackenzie.

Canadian crude may have been sent toward Cushing as feedstock for a restart of the Toledo refinery, which had a fire last year, said Matt Smith, lead oil analyst for the Americas at Kpler.
