Big world oil companies returning to Iran market

The Royal Dutch/Shell group, one of the biggest Western oil multinationals, is to buy about 100,000 barrels per day of crude from Iran under an accord that takes it back to the Iranian market after a nine-month absence, oil industry sources said. Another European oil major, British Petroleum, which also stopped buying from Iran last April after a Western embargo was imposed, confirmed that it was having talks in T ehran.
