Oil prices have climbed 6.7 percent this week as refinery shutdowns in Texas, Louisiana and Venezuela threatened to curb fuel supplies. U.S. gasoline inventories are down 5.7 percent since the end of February, more than double the five-year average, boosting demand for crude to fill gaps in fuel output.

A gasoline-making unit at a Lake Charles, Louisiana, refinery owned by ConocoPhillips, the largest U.S. refiner, yesterday failed to start after maintenance, Reuters reported, without naming its source. Conoco spokeswoman Laura Hopkins declined to comment.
San Antonio-based Valero, the third-largest U.S. refiner, on April 18 said a coker at its St. Charles, Louisiana, plant will be shut until at least April 26, halting 336,000 gallons of daily gasoline output and 1.05 million gallons of daily distillate production. Distillates include diesel and heating oil.
Petroleos de Venezuela SA, South America's largest oil producer, last week stopped gasoline and diesel production at its Puerto La Cruz refinery after one of the plant's units was shut, El Nacional reported today, citing unidentified industry officials.
``It looks like problems with refineries in the U.S. are making people nervous about not getting enough gasoline for the summer season,'' said Anette Einarsen, an oil analyst in Oslo for Nordea Bank AB. ``The market is also jumpy because of the uncertainty of how much demand will actually grow compared to production from refineries.''
