The Organization of Petroleum Exporting Countries,or OPEC, weighed a push by some members Monday to modestly boost its production quota, in the face of stubbornly high oil prices.

On the eve of Tuesday's OPEC meeting in Vienna, Austria, half a dozen key members, including Iran, Kuwait, Nigeria and Venezuela-say they believe the markets are well supplied.

They suggest the official output quota of 25.8 million barrels per day should stand. But oil analysts say some Gulf states are pressing for a small but symbolic increase of 500,000 barrels a day to reassure jittery markets.
