West Texas Sour oil weakened to the cheapest versus benchmark West Texas Intermediate in almost seven weeks because of decreased demand during refinery maintenance and growing production.
Work on a shut crude unit and reformer at Western Refining Inc. (WNR:US)’s El Paso, Texas, refinery is expected to last about two weeks or less, Gary Hanson, a company spokesman, said yesterday. Eagle Ford production of oil and condensate has grown to average between 550,000 and 600,000 barrels a day, Phani Gadde, a senior analyst with Wood Mackenzie, a research and consulting firm in Houston, said in a telephone interview.
