The Organisation of the Petroleum Exporting Countries said in a statement that a meeting would take place on the sidelines of the International Energy Forum in Algeria from September 26 to 28, ahead of a planned meeting due at the end of November.
Analysts said markets were reacting to rumours that global producers were mulling a deal to freeze oil output levels.
"News that OPEC would be having a September meeting with certain members keen to push for supply cuts again served as the impetus for oil prices to rally," said Angus Nicholson, a strategist at IG Markets Ltd. In Melbourne.
But in Asian trade, prices fell back as investors weighed whether the meeting would bring about any tightening of supply, according to Bloomberg.
At around 0430 GMT, West Texas Intermediate was down 36 cents to USD 42.66 while Brent lost 41 cents to $44.98.
Prices have been fluctuating since entering a "bear" market last week, falling more than 20 percent and closing below USD 40 a barrel for the first time since April.
If accurate, this would be a vindication of its strategy since 2014 of squeezing non-OPEC suppliers by keeping production at high levels despite low prices.
"Nobody seriously thinks that OPEC will come up with anything that will tighten supply," Michael McCarthy, a chief strategist at CMC Markets in Sydney told Bloomberg News.
"Having bounced off the support near USD 40, and without any further supply coming online, we're moving toward the middle of the trading range of about USD 44 to USD 45 for West Texas.
