The slump in oil prices, which had been driven by a glut in global supplies, has mostly passed, OPEC Secretary General Abdallah Salem el-Badri said.
"The oil market is rallying, the price is increasing, I think that bad times, the bad period has been put behind," Sputnik cited him as saying.
The OPEC oil ministers may discuss oil production quotas at Thursday's meeting in Vienna, Badri added.
