据管道&天然气杂志网6月22日报道，美国俄克拉荷马州库欣储存中心的原油库存已升至两年来的最高水平，因为美国中西部炼油厂的停产抑制了需求，而来自加拿大的原油流量增加了供应。

美国原油期货交割点库欣的库存在今年早些时候下跌后，已连续八周攀升。据分析师表示，海外对美国原油的需求和炼油厂停产的结束应该会扭转这种局面。

价格期货集团（Price Futures Group）分析师菲尔·弗林表示，“我们将向海外出口更多(石油)。从整体来看，供应方面仍然紧张”。

根据EIA的数据显示，中西部地区一连串意外的炼油厂停产增加了库存。6月9日当周，库存增至4210万桶，为2021年6月以来的最高水平。

分析机构IIR Energy高级主管希拉里·史蒂文森(Hillary Stevenson)表示，该公司5月份在美国中部追踪到57.9万桶/天的原油停产量，是去年同期25.6万桶/天停产量的两倍。

Stevenson补充道，bp和Cenovus Energy Inc.位于俄亥俄州托莱多的日产16万桶炼油厂以及Phillips 66位于得克萨斯州Borger的日产14.9万桶炼油厂相继停产可能导致库欣库存增加。

伍德麦肯兹北美原油市场首席分析师约翰·科尔曼（John Coleman）表示，来自加拿大的稍高流量也增加了供应量，恩桥公司Flanagan South管道5月和6月至今的流量也有所增加。

数据分析机构Kpler美洲首席石油分析师Matt Smith表示，加拿大原油可能已被送往库欣，作为去年发生过火灾的托莱多炼厂用以重启的原料。

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.
