NEW YORK, April 21 (Reuters) - Oil prices rose slightly on Wednesday, as the resumption of European flights and strong Chinese demand outweighed a bearish rise in U.S. crude and refined product inventories.
U.S. heating oil futures, the benchmark to trade jet fuel, led the oil complex higher. Flight bans, related to an ash cloud caused by an Icelandic volcanic eruption, were lifted on Tuesday, alleviating concerns some investors had over the impact the disruptions would have on fuel demand. [
]"The only token support I can see on this heating-oil led rise in crude futures is some fundamental support developing as European airports have reopened after being disrupted for days by the spread of the Icelandic volcanic ash," said Tim Evans, analyst at City Futures Perspective in New York.
"And that is restoring some jet fuel demand that had been absent recently," Evans added.
U.S. crude futures <CLc1> traded up 26 cents to $84.11 a barrel by 2:03 p.m. EDT (1803 GMT), after dropping to a session low of $82.92 in the wake of the EIA inventory report. ICE Brent crude <LCOc1> gained $1.10 to $85.90 a barrel.
U.S. crude oil inventories rose 1.9 million barrels last week, against the forecast for a slight drop, the Energy Information Administration (EIA) oil inventory data showed. [
]Distillate and gasoline stockpiles increased more than expected. Analysts said the inventories builds raised concerns about recovery of U.S. fuel demand, which was hit hard by the recession.
"Crude futures are up, but this shouldn't be the case here, looking at inventories, particularly product stocks, being up. The fundamental picture shows there is no strong case for prices going up," said Gene McGillian, analyst at Tradition Energy in Stamford, Connecticut.
"Also, the equities market is down and the dollar is up. However, prices appear to have underlying support from China where oil imports remain bubbly," he added.
Further support came from data showing China's implied oil demand in March rose 12.3 percent from a year earlier, the seventh month of double-digit growth in a row, as warming weather boosted dormant farming activities.
The world's second-largest oil user consumed 8.25 million barrels of oil per day last month, 4.6 percent or 400,000 bpd less than February, according to Reuters calculations based on official data. [
]A strong dollar has also held down any gains for crude. The euro fell for the fifth day against the greenback due to ongoing uncertainty about Greek's debt crisis. [
