Crude oil rebounded slightly on the New York Mercantile Exchange Thursday, climbing above $86 per barrel with traders recalibrating positions based on supply data. Reduced tensions in the Middle East have erased expectations of supply shortages. It was forecast this week that suppliers who increased production to make up for lost supplies have now flooded the market by as much as 630,000 barrels per day. After a sharp drop earlier in the week, December delivery West Texas Intermediate crude oil added 65 cents to $86.38 per barrel in New York. Natural gas prices lost 3.8 cents to $3.412 per million British thermal units. Home heating oil added 2.67 cents to $3.0531 per gallon. Reformulated blendstock gasoline gained 3.2 cents to $2.6233 per gallon. At the pump, the average price for a gallon of regular unleaded gasoline was $3.599 per gallon, down from Wednesday\'s $3.625, AAA reported.
