LONDON, Oct 7 (Reuters) - Oil prices rose for the third straight day on Wednesday, edging above $71 a barrel after an industry report showed a drawdown in U.S. crude inventories, boosting the view demand is recovering.
U.S. crude for November delivery <CLc1> rose 26 cents to $71.14 a barrel by 0937 GMT, adding to Tuesday's gains of 47 cents. London Brent crude <LCOc1> rose 32 cents to $68.88.
Oil's gains followed a report by the American Petroleum Institute saying crude stocks fell 254,000 barrels in the week to Oct. 2, defying forecasts in a Reuters poll of analysts for a 2.2-million-barrel increase. [

The API report is seen as a precursor to the more authoritative data issued by the U.S. Energy Information Administration (EIA), which will be released at 10:30 a.m. EDT (1430 GMT) on Wednesday.
The EIA also raised its global oil demand estimate by 170,000 barrels a day for the fourth quarter and said it expected consumption to rise by 1.1 million bpd next year, versus earlier expectations of a 910,000 bpd rise. [
]The second day of gains for Asian and European shares, on growing confidence that a global economic recovery is underway, gave oil prices an extra lift.
Oil has rebounded from an 11-week low of around $66 in late September back above the $70 level, but some analysts caution it could slip back in the near term.
"Oil looks like it's on shaky ground as we approach the U.S. third quarter (corporate) reporting season. A lot of near term price gains have been won off a rebounding equity market," said Mark Pervan, a commodities analyst at the Australia & New Zealand Bank.
"I suspect the third-quarter reporting card will struggle to match the impressive second-quarter results, which were mainly driven by one-off aggressive cost cutting."
After having jumped by around 40 percent in the second quarter, oil prices have squeezed out a gain of only 1 percent in the last quarter, trading in a band of between $65-$75.
While the global economy is healing from the financial crisis, the recovery, along with energy demand, remains fragile.
A U.S. Federal Reserve official said on Tuesday that while the world's largest economy was clearly rebounding, it was too soon to begin to withdraw the Federal Reserve's massive support. [
]Weakness in the U.S. dollar is also supporting commodities priced in the greenback as they become cheaper for holders of other currencies. [
]Gold <XAU=> has risen to a series of record highs over the past two days, with the precious metal touching $1,048.20 an ounce on Wednesday.
The Australian dollar has been buoyed to 14-month highs due to higher interest rates and stronger commodity prices. [
