（彭博社）“严寒席卷美国，导致北达科他州一半以上的石油生产关闭，德克萨斯州的炼油厂运营受到限制。

美国第二大页岩盆地的停电短暂提振了西德克萨斯中质原油期货。由于中西部炼油商寻求北达科他州巴肯石油的替代品，墨西哥湾沿岸的实物石油价格也上涨。

北达科他州管道管理局局长贾斯汀·克林斯塔德 (Justin Kringstad) 表示，目前的产量已达 65 万桶/日，高于周一的 42.5 万桶/日。10 月份该州总产量达到 1.2 MMbpd。

寒冷的气温也阻碍了该国石油加工中心德克萨斯州的炼油厂的发展。埃克森美孚的贝敦炼油厂被迫降低两个装置的产量，而弗林特山炼油厂则削减了科珀斯克里斯蒂一个装置的运营。

休斯敦现货柴油交易相对于 Nymex 期货的折扣收窄至两个多月以来的最低水平，而汽油价格每加仑比期货价格低 9 美分，为约三个月以来最强劲的相对价格。

(Bloomberg) – Freezing temperatures sweeping the U.S. shut in more than half of North Dakota’s oil production and curbed refinery operations in Texas.

The outage in the second-largest U.S. shale basin briefly lifted West Texas Intermediate futures. Physical oil prices also rose on the Gulf Coast as Midwest refiners seek alternatives to North Dakota’s Bakken oil.

As much as 650,000 bpd is offline, up from 425,000 bpd on Monday, according to Justin Kringstad, director of the North Dakota Pipeline Authority. The state’s total production reached 1.2 MMbpd in October.

Freezing temperatures also hobbled refiners in Texas, the country’s oil processing hub. Exxon Mobil’s Baytown refinery was forced to reduce rates at two units, while Flint Hills cut operations at a unit in Corpus Christi.

Spot diesel trading in Houston firmed to its narrowest discount to Nymex futures in more than two months, while gasoline fetched 9 cents a gallon below futures, its strongest relative value in about three months.
