Crude oil prices held near $93 per barrel Tuesday but found support from a supply glitch in oil from the North Sea. An equipment failure in the Buzzard North Sea oil field disrupted production temporarily, which helped give prices a boost. That was offset by mixed economic data released Monday. On the New York Mercantile Exchange, West Texas Intermediate crude shed 11 cents to $92.81 per barrel. Reformulated blendstock gasoline lost 1.76 cents to $2.7895 per gallon. Heating oil added 1.13 cents to reach $2.8303 per gallon. Natural gas prices added 2.5 cents $4.007 per million British thermal units. At the pump, the average price of a gallon of regular unleaded gasoline was $3.619 Tuesday, down from Monday\'s $3.623, the AAA Fuel Gauge Report said.
