Iran Monday warned OPEC's current excess oil production could increase oil-inventory levels and said the organization hasn't yet reached a consensus on its next secretary general, Iran's oil ministry website Shana said.

The remarks highlight key points of contention for the Organization of Petroleum Exporting Countries to discuss when the group meets Wednesday in Vienna for the first time since June.

Iran's envoy to OPEC, Mohammad Ali Khatibi, said the organization is producing one million barrels per day more than the market needs, according to the Shana website.

Mr. Khatibi joined other voices in the group who have cautioned that OPEC is producing too much oil for its own good.

In October, OPEC produced about 30.9 million barrels a day, according its latest monthly report.

By contrast, OPEC says markets will need on average 29.7 million barrels a day of its crude next year.

Mr. Khatibi said the excess supply could boost oil inventories--a situation that would tend to exert downward pressure on oil prices.

Last week, the U.S. Energy Information Administration reported a bigger-than-expected increase in U.S. gasoline supplies, up by 7.9 million barrels compared with the previous week.

Mr. Khatibi also said OPEC has yet to reach a consensus on which candidate will replace the organization's current Secretary General Abdalla Salem el-Badri, who is set to leave his position at the end of the month.

Mr. Khatibi called on OPEC to devise strict criteria for choosing its secretary general in order to avoid future squabbling over the leadership appointments.
