输油管道已满，铁路运输成不二选择

据美国彭博新闻社卡尔加里报道，由于预计铁路运输的原油发货量将会增加，加拿大重质原油价格相对于美国基准原油期货价格的跌幅降到了4月份以来的最低水平。

彭博社汇编的数据显示，油砂基准西加拿大精选原油价格(Western Canada Select)周二比西德克萨斯中质原油价格每桶下跌了1.30美元至9.20美元。加拿大太平洋铁路公司表示，加拿大第三季度铁路原油日运输量预计比第二季度的大约16万桶增加20%，而加拿大重质原油价格将因此会飙升。

由于输油管道已满，通过铁路运输原油已成为原油生产商将过剩原油运出艾伯塔省的唯一真正选择。自今年1月以来，该地区最大的几家油砂生产商一直处于强制性生产限制之下。此前，产量的不断上升将西德克萨斯中质原油价格压低至每桶50美元。

包括Cenovus能源公司和森科尔能源公司在内的加拿大石油公司的负责人提出，他们将提高铁路运输的原油数量来换取更高的产量限制。

Canadian heavy crude surges as rail shipments increase

Heavy Canadian crude prices narrowed to the smallest discount against U.S. benchmark futures since April as crude-by-rail shipments were forecast to increase.

Western Canadian Select, an oil sands benchmark, shrank $1.30 to $9.20/bbl below West Texas Intermediate crude Tuesday, data compiled by Bloomberg show. Prices surged after Canadian Pacific Railway said crude-by-rail volumes were expected to rise 20% in the third quarter from about 160,000 bpd in the second quarter.

With pipelines full, crude shipped by rail has become the only real alternative left for producers to send excess oil out of the province. The region’s largest producers have been under mandatory production limits since January after rising production drove WCS prices as low as $50/bbl below WTI.

The heads of Canadian oil companies including Cenovus Energy and Suncor Energy are offering to boost crude-by-rail shipments in exchange for higher production limits.
