TOKYO, Nov 19 (Reuters) - Oil erased early gains to below $82 a barrel on Friday, as Asian stocks pared gains and technicals indicated weakness ahead of the weekend, after sharp rises on an improved outlook for Ireland's debt crisis.
U.S. crude for December delivery <CLc1>, which expires after Friday's settlement, was trading down 41 cents at $81.44 a barrel by 0509 GMT, after rising as high as $82.50 earlier.
Oil, which settled up $1.75 on Thursday, still remains well below a 25-month high of $88.63 hit on Nov. 11, but recovered after hitting a four-week low of $80.06 on Wednesday amid concerns about the euro zone's fiscal health.
Oil could drop back to $80.06 per barrel as its rebound could have fizzled, Wang Tao, Reuters technical analyst, said on Friday.
London Brent crude <LCOc1> was trading 44 cents lower at $84.61 a barrel.
"Precious metals such as silver and palladium are climbing and so are stocks, boosting market sentiment," said Shuji Sugata, a manager at Mitsubishi Corp Futures. "There are slight signs of risk-taking, but new position taking is difficult because volatility is high at the end of the week."
Prices received support earlier from a 7.3 million-barrel drawdown in crude stocks in government data reported on Wednesday, the biggest weekly fall in 14 months.
The euro held on to its recent gains on Friday on budding hopes that Ireland is near a deal to shore up its banks and budget deficit, although the currency stopped short of breaking above major resistance.
Ireland's central bank chief said he expected the country to receive tens of billions of euros in loans from European partners and the IMF to help shore up its troubled banks and stabilise the economy. [
