西得克萨斯中间基原油West Texas Intermediate 简称WTI的价格是国际石油市场的一种基准价格，也是纽约商品交易所石油期货合同的标的物。所有在美国生产或销往美国的原油，在计价时都以轻质低硫的WTI作为基准油。

在新闻报道里，和北海布伦特原油价格一样，WTI的价格常常被做为反映当前世界石油市场的参考价格。其他重要的世界石油市场价格还包括迪拜原油价格和石油输出国组织（OPEC）的一揽子参考价格。

[编辑] 特性

西得克萨斯中间基原油是一种轻质原油，比布伦特原油要轻，含硫量只有0.24%。它的产地和特性决定了绝大部分的西得克萨斯中间基原油的精炼都是由美国中西部和墨西哥湾地区的炼油厂所完成。

WTI的API重力值为大约39.6。

[编辑] 价格

Historical price data for WTI can be found at a website maintained by Energy Information Administration, Department of Energy of the US government. It is listed as WTI, Cushing, Oklahoma [1].

Typical price difference per barrel is about $1 more than Brent, and $2 more than OPEC Basket.

[编辑] 2007

Although WTI is supposed to gain a higher price than that of Brent crude, on May 24, it was priced at $63.58 per barrel as against $71.39 per barrel for Brent (Bloomberg). There seem to be other factors leading to the change in price differential. On April 13, 2007, WTI Crude at Cushing may have temporarily lost its status as a gauge of world oil prices^[1]. A large stockpile of oil at the Cushing, Oklahoma storage and pricing facility (mainly due to a refinery shutdown^[2]) has caused prices to be artificially depressed at the Cushing pricing point. While stockpiles remain high, refiners are coming back to full capacity to meet early demands for summer gasoline consumption, which could help return storage to reasonable levels again. ^[3]
