Crude oil prices rebounded Wednesday morning, closing in on $100 per barrel as stocks markets showed gains in Asia and Europe. A weekly U.S. inventory report is issued late Wednesdays. A rise before the report, like the tail wagging the dog, can indicate that traders believe supplies are down. Light, sweet crude oil on the New York Mercantile Exchange added $1.31 overnight to reach $99.62 per barrel. Home heating oil gained 0.33 cents to $3.1942 per gallon. Reformulated blendstock gasoline gained 1.04 cents to $2.9379 per gallon. Natural gas prices gained 0.2 cents to $2.474 per million British thermal units. At the pump, the national average price of unleaded gasoline rose to $3.483 per gallon Wednesday from Tuesday\'s $3.48, AAA said.
