(Updates prices)

LONDON, June 11 (Reuters) - Oil jumped more than $3 to near $135 a barrel on Wednesday after oil major BP <BP.L> said the world's proven oil reserves were mostly unchanged last year, a further indication of tightening global oil supplies.
Prices also rose ahead of U.S. weekly oil data, which is forecast to show a drop in crude inventories later in the day.
U.S. crude <CLc1> leapt $3.59 to $134.90 a barrel and was trading at $134.63 by 1340 GMT. In the past two days, it had fallen by more than $7.
London Brent crude <LCOc1> was trading $2.79 higher at $133.81.
The world's proven oil reserves were essentially flat in 2007 while production fell by 0.2 percent, the first decline since 2002, BP reported on Wednesday, when it launched its 2008 Statistical Review of World Energy. [
]On Tuesday, the International Energy Agency, the energy adviser for the world's industrialised countries, sharply lowered its projection for supply outside the Organization of the Petroleum Exporting Countries. [
]Concern over long-term oil supplies has driven the recent spike in oil prices and prompted Wall Street banks to raise their price forecast to about $150 and $200.
"For sure, banks tend to focus on supply. It is easy for them to make assumptions of $200," Olivier Jakob with Petromatrix said. "On the other side, we have to look at price impact on demand. That's why the market is so volatile."
Oil's six-year rally has accelerated this year, with around a 40 percent increase in prices since the start of 2008. It hit a record high of nearly $140 a barrel last Friday.
The U.S. Energy Information Administration (EIA) will release weekly oil stocks data at 1435 GMT on Wednesday.
Analysts polled by Reuters forecast a 1.1 million barrel drop in crude inventories, the fourth straight week of draws.
Gasoline stocks are forecast to rise 1.2 million barrels, the second straight weekly increase, because production rose and demand has been hurt by high pump prices. [
]In contrast, China, where oil demand is growing the most rapidly, imported 25 percent more crude in May than a year earlier. [
]Saudi Arabia will host a meeting of oil producers and consumers on June 22 to discuss the high prices, OPEC Secretary-General Abdullah al-Badri told Reuters on Tuesday. [
]Traders were sceptical that could help tame prices.
"There seems to be a feeling that a meeting in Saudi and even an increase in production would not halt price rise in oil," one broker said.
