LONDON, April 22 (Reuters) - Oil fell below $83 per barrel on Thursday after higher U.S. inventories signalled demand in the world's top oil consumer was sluggish despite the global economic recovery.
Crude stocks in the United States rose unexpectedly last week, government statistics showed, and fuel supplies climbed more than forecast. [
]European oil industry data added to the bearish tone with figures from industry monitor Euroilstock showing oil refinery output in 16 European countries fell by 10.1 percent in March from the same month last year. [
]U.S. benchmark June light crude oil futures, also known as West Texas Intermediate (WTI), <CLc1> dropped more than $1 per barrel to a low of $82.30 before recovering slightly to trade around $82.50 by 1310 GMT. The front-month contract reached an 18-month high above $87 on April 6.
U.S. prices came under pressure from figures on Wednesday showing a 1.8-million-barrel rise to over 34 million barrels last week in crude oil inventories at Cushing, Oklahoma, the landlocked pricing point for NYMEX crude futures.
The Energy Information Administration (EIA), said the increase at Cushing was responsible for most of a national U.S. crude oil stocks rise of 1.9 million barrels.
But ICE Brent crude futures <LCOc1> held up better than U.S. futures and June Brent was trading around $2 higher than WTI on Thursday, down 87 cents at $84.83 a barrel.
North Sea crude supplies will tighten over the next month due to offshore maintenance work and Brent is also responding to evidence of more Chinese demand, analysts say. [

Carsten Fritsch, energy analyst at Commerzbank, said the EIA report was still weighing heavily on the oil market.
"Our view is that oil prices are somewhat decoupled from fundamentals at the moment and do not yet reflect the high level of stocks," Fritsch said.
"AHEAD OF FUNDAMENTALS"
Edward Meir, analyst at brokers MF Global, highlighted what he saw as the potentially negative influence of the dollar on oil as the euro remained under pressure after dropping against the dollar for a fifth day in a row on Wednesday.
The dollar was up around 0.45 percent against a basket of currencies on Thursday. [
] <EUR=>"We would suggest that prices have gotten somewhat ahead of the fundamentals," Meir said. "We are consequently looking for a modest pullback over the short-term, particularly if the dollar continues to strengthen on the back of the Greek debt crisis."
China's apparent oil demand in March rose 12.3 percent from a year earlier, the seventh double-digit increase in a row, according to Reuters calculations from official data released on Wednesday. [
]Rising consumption in China, the world's second-largest oil user, has helped support crude prices as demand from developed economies struggles to rebound from the recession.
The market received some support from news of an explosion early on Thursday on the Iraq-Turkey oil pipeline which carries a quarter of Iraq's crude exports. [
]The pipeline blast in the northern Iraqi province of Nineveh is likely to affect oil exports via the Kirkuk to Ceyhan pipeline for as much as a week, Iraqi officials said. (Additional reporting by Alejandro Barbajosa in Singapore; editing by William Hardy)
