PETROLEUM prices firmed yesterday as the market took the view that

Iraq's resumption of oil sales would be delayed.

That would give a divided Opec (the Organisation of the Petroleum

Exporting Countries) a breathing space to try to agree on how it would

prevent a glut.

London September futures for the benchmark Brent Blend of crude oil

traded up to $16.84 per barrel. This was up 15 cents on the day and

almost a dollar stronger than a week ago.

Last Monday prices tumbled on a belief that the United Nations would

soon ease the embargo on Iraqi oil which it imposed when Iraq invaded

Kuwait in 1990.

Prices recovered when Opec announced it would hold an emergency

meeting but this later had to be put off as Saudi Arabia and Iran feuded

publicly.

Iran said Saudi Arabia's quota was too high. The Saudis blamed weak

prices on quota violation by Iran. Neither wants to concede market share

before Iraq returns to the market.

Opec president Jean Ping of Gabon flew home from a tour of the Gulf

yesterday after trying to find ''a minimum consensus'' that would enable

him to set a new date for Opec talks.

The next scheduled session is on September 25. Opec delegates said

this meeting could, if judged necessary, be advanced to late August or

early September.

Diplomats suggest that there may be no quick result in Iraq's talks on

the oil embargo with the United Nations. They say Iraq may stall on

current negotiations to sell a small volume under supervision in the

hope that the embargo might soon be lifted entirely, if it complies with

UN weapons inspectors.

The Middle East Economic Survey (Mees), an authoritative oil

newsletter, said yesterday that current Opec production was around

24,600,000 barrels daily. This is already one million above the current

official ceiling.

Mees saw a danger that prices might collapse if Iraq sells oil and the

rest of Opec still cannot agree quotas that all the members accept.

Besides Iran and Saudi Arabia being at loggerheads, Kuwait is refusing

to accept an assigned quota which it calls unfair.
